Unraveling the Art and Science of Machine Screw Thread Design - Technology Org

The screw threads are a fundamental component of various household devices and industrial machinery. Their production is a result of a precision machining process, where a thread is imprinted using a pair of stationary and rolling dies.

However, before the actual manufacturing begins, the screw follows a critical design process. This article uncovers all aspects of screw thread design, from thread profile and material selection to its stress analysis and production.

Thread Profile Selection

The initial step of machine thread design is the selection of a profile i.e. the cross-sectional shape of the thread. For different applications, you’ll need different thread profiles. Typically, machine screw threads are designed in three shapes, V-shape, Square, and ACME.

V-shaped threads are the common ones, used for general purposes. These threads adhere to the ISO and Unified Thread Standard (UTS). Their V-shaped symmetrical makes them ideal for fastening applications as they provide a high frictional force. This design also ensures a firm grip, which is crucial for sturdy connections.

Square threads are recognized from their square-shaped profile. This design offers the least friction, which makes them ideal for high-load and power transmission applications. You’ll see such threads in presses, screw jacks, and clamping devices. However, square threads come with challenges. They’re tough to machine because the tools used can’t have optimal rake and relief angles. Additionally, they cannot bear as much load as trapezoidal threads due to their smaller root.

Acme threads were introduced in the late 1800s as a better version of square threads. Square threads were sound for power applications but had structural vulnerabilities due to their sharp angles. Acme threads have a 29-degree thread angle, which provides a sturdier profile compared to conventional V-shaped and square threads.

The design makes them suitable for applications where torque or power transmission is required. For instance, in lathes, presses, or milling machines. They do excel in dirty environments, thanks to their engineered design and thickness

The acme threads are prevalent in the United States. While in Europe, there’s an upgraded version, with a 30-degree angle, called trapezoidal thread which is known to have superior load-bearing abilities.

Thread Tolerances and Fit

After profile selection, tolerance is what makes the screw compatible for mating. It ensures perfectly aligns and binds the machine components. A fully functional design also defines the tolerance which is the deviation from its specified dimensions.

Since the manufacturing process isn’t 100% precise, there’s always a probability that the designed thread would slightly deviate from its dimensions. The manufacturer specifies this tolerance on the thread. The theoretical design also keeps in view the tolerance factor to make sure everything fits in perfectly despite slight variations.

If you’ve tried to read a machine screw thread (an ISO standard one), it has something like M12 x 1 – 5g6g written on it. Here, 12mm is the nominal diameter, 1mm is the pitch, and 5g6g is the tolerance.

If we break it down further, the numerical value (in 5g) is the tolerance grade. The lower the number, the tighter the tolerance. For instance, Grade 6 signifies a medium tolerance quality. It is suitable for standard thread engagement lengths. Lower grades like 4 or 5 indicate fine tolerances for short thread engagements, while higher grades like 7 or 8 denote coarser tolerances for longer engagements.

The letters indicate the tolerance position. h is for zero deviation and g is for positive deviation. A positive deviation means the thread element size will be larger than the basic size, while a negative one indicates it will be smaller.

Thread Material Considerations

Material is always a primary factor in machine screw thread design. Because it’s after all the material whose inherent properties will reflect and dictate the use of screws.

Material selection is influenced by multiple factors like material hardness i.e. how much will the screw will resist stripping over time. For instance, steel is one of the hardest materials and a common choice for making machine screws.

Another property is thermal expansion. It determines how a material expands and contracts with temperature changes. While making a material choice, you’ve to make sure the screw and its mating components have somewhat similar expansion coefficients. For example, aluminum has a higher coefficient of thermal expansion than steel. If an aluminum screw is used with a steel component, and they are subjected to temperature variations, there would be issues with fit and stability over time.

Corrosion is a natural process, and material decays in a corrosive environment. You need materials that have high corrosion resistance. For those coastal areas or applications where water exposure is inevitable, copper is a choice due to its exceptional corrosion resistance. Moreover, it’s also used as a coating on other screws along with zinc (another great coating material for screws).

Apart from steel and copper, aluminum and titanium are also good candidates for machine screws. Aluminum may not be as hard as steel yet it lightweight making it great for aerospace applications. Titanium is a combination of both lightness and high strength, but it’s a costly option.

Thread Stress Analysis

Stress analysis is the final nail in the coffin. Consider it as a checkpoint, which passes or fails your theoretical design and material. Once it was a tough job; one had to sketch all the mechanical stresses and strains (Tensile, compressive, shear) on paper. And then calculate the screw failure, based screw design standards and equations. However, with tech evolution, numerous software solutions have emerged.

With multiple computational stress analysis tools (like ANSYS, CATIA, and SolidWorks), you can check the feasibility of your design; and how it will perform in physical settings. You can configure materials, operating conditions, and the loads a machine screw would ideally bear during its working. All this can be simulated and precise results can be obtained within minutes.

Conclusion

After these careful design steps, right from the thread profile selection to the stress analysis, next comes the physical phase, the manufacturing. Normally, a cold heading process is performed to make the screw head, and then the screw passes through roller dies, one stationary and another rotary. They print threads onto it. The process is fully automated with large screw machines that produce hundreds of threaded screws in minutes.

Iceman, Slider, Cougar, and Goose wear rings that show they are graduates of the United States Naval Academy, supported by their dialogue in the film and the ornate rings they wear throughout the film. I know Goose is married, but that ring is far too large to be just a wedding band. (I promise this isn't an info dump... not like my others anyway)

The USNA is an undergraduate college that is a combination of academics and military development programs. Based on the current list of majors available at the United States Naval Academy, I think that Iceman, Slider, Cougar, and Goose likely would have chosen one of the following majors: Aerospace Engineering, Electrical Engineering, General Engineering, Mechanical Engineering, Physics, Chemistry, or Mathematics, but they could have gotten a degree in something like English, Foreign Area Studies, Political Studies, History, etc. Again, these are based on the list of current majors offered, so take that with a grain of salt, but I still feel like it’s possible that a majority of these were offered in the late 1970s and early 1980s.

In my mind, I can see Iceman being a bit of an overachiever. He would major in Aerospace Engineering with a minor in Political Science while playing on some Varsity sports team (he’s too cool not to be in). Maybe something like Lacrosse or Swimming and Diving, but regardless I can totally see Ice and Slider meeting by being in the same sport. And swimming definitely fits their vibes ngl. But also Slider could def be a true American football player and if Ice plays lacrosse (which is a spring sport) they could go to each other's games. I’m not sure if they had Men’s Club Volleyball when they would have attended like they do now, but I’m sure they would have made time to play when able. A lot of people headcanon Ice as being Russian, which makes sense because his last name is Russian in origin, but regardless of that fact I feel like he would have participated in the Naval Academy Foreign Affairs Conference. An excellent resume builder and an asset for an aspiring admiral, the NAFAC is a conference hosted by the USNA in which students from around the US come together to discuss a theme from current global affairs.

I want this fanfic so bad man

It's eating my brain!! I can't stop world building!

Like, they go to different colleges maybe but in the same city? Probably have an apartment instead of dorms for that reason.

Matthew goes to a college more famous for sports than academics obviously. Studies something like bio or forestry or journalism, whatever. I kinda like forestry? He's really there for the hockey. Scholarship, obviously. Plays lacrosse in the spring, but it's more just to keep in shape for hockey. Tino, Berwald, Mathias, and Ivan are on his team. Katya goes to the same school but is an upperclassman. Ivan goes there because his sister does, and also has a hockey scholarship but he moonlights aerospace engineering classes at the other college.

Matt was the quiet kid in high school who you were shocked to find out went to underage drinking parties and got arrested for smoking pot and setting things on fire.

Alfred got an academic scholarship to some big time tech school - engineering, physics, aerospace, computer programming, etc. Would play baseball except he's too focused on his studies but he and Kiku go to every game. Gilbert probably goes there. Eduard, Kiku, and Ludwig definitely do.

In high school, he did Mathlettes and baseball, as well as played the violin, and figure skating. You know, that kid with way too many hobbies who you wanted to hate because he excelled at everything but he was too damn friendly.

Obviously in highschool everyone knew them but now that they're in (different) college and their teachers and classmates don't know about the identical twin thing, which is about to save Matt's ass with the drug test thing.

Or, at least, that's their one braincell-ed plan.

Please send help.

Overview

Proposed as part of Project BIG CAT for the Magistracy of Canopus, the Yaguara was designed by Majesty Metals and Manufacturing in 3146 as a fast moving, hard-hitting heavy 'Mech.

This custom variant, built for Inanna Allard-Liao, possesses an extremely dangerous close combat weapon - a 'Mech vibroblade, mounted on a 'Mech-scale myomer tail, in addition to most of the weaponry of the base configuration.

Capabilities

The Yaguara was built from the ground up with speed and long-ranged engagement in mind. Built around a supercharged Vlar 300 XL engine, the 'Mech can sprint over 86 kph, allowing it to keep up with lances comprised of much lighter 'Mechs than itself. It complements this ground speed with four Rawlings Model 60 jump jets, granting it a jumping distance of 120 meters for an extra mobility boost. Its armament is built around a pair of Clan-spec ER Large Lasers, uncommon in the region, and a Class-2 Rotary Autocannon, with a pair of SRM 6s and medium pulse lasers as close-engagement backups. All of this, unfortunately, comes at the cost of heat - the Yaguara was designed with bracket fire in mind, and MechWarriors are advised not to alpha strike without due cause. This custom variant was built for Inanna Allard-Liao. It is a hybrid Clantech refit, using many experimental technologies, as well as the removal of the previously-mounted SRM 6s, to allow for the addition of a custom myomer armored tail, with a 'Mech scale vibroblade mounted to the end. Complimenting this weapon are Triple-Strength Myomer and a Supercharger, to allow the 'Mech to reach truly incredible speeds for its weight.

Controlled by Inanna using a salvaged Word of Blake Buffered VDNI system, the 'Mech moves with the same fluid grace as its pilot. Advances in Belter/Canopian hybrid medical science have extended Inanna's lifespan estimate from 15 years to 75, and are predicted to have significantly extended the initial onset period for the madness which often accompanies use of neural interface systems.

Chapter 12: Nonna's Special Sauce

Friday dawns with the expected breakfast racket. You groan as you wake up and roll over to burrow in Jake's chest, not ready to be up yet. Jake's arms reflexively wrap around you and he keeps sleeping. You enjoy the warmth and closeness for a while till Jake wakes up.

"I'm sorry that my parents are obscenely loud in the morning," he mumbles into my hair.

"I promise it's worth it, my mom makes some kind of potato omelet thingy with some of the leftovers from yesterday and it's delicious."

"Sounds interesting and I know there's coffee down there, so it's not too bad. Would probably prefer to be waking up to songbirds or some shit like that," you mumble back to his chest. You feel him laugh more than hear it.

You and Jake rally and get out of bed and head downstairs to coffee and the promised potato omelet thingy. Which as advertised is excellent. Jake and you migrate to the living room with your cups of coffee after breakfast and lounge on the couch.

"What's the plan for today?" you ask Jake.

"Nothing until the Lucarelli get together later this afternoon. Probably see if my mom needs help cooking anything. So as much Netflix and chill as we want," he says wagging his eyebrows without a trace of subtlety.

He earns a laugh from you,

"You don't need any encouragement.

The day turns out as expected. You laze about, putter around getting ready, helping Sharon with any cooking tasks, and just hanging out.

Around 3 pm, it's officially go time for the Lucarelli get together and soon you are loading the car with an obscene amount of food and wine.

Soon you pull up to another gorgeous ranch house. The driveway is filled with vehicles. Jake and you help Sharon with the food she's made and the wine. Tom grabs another bag that he has deemed his gin and tonic kit and you all approach the front door. Tom doesn't bother to knock and just as soon as he opens the door you can hear the sound of a family party spilling out. There's the sound of kids running, playing, and shrieking with delight, lots of conversations, laughing and the general hum of people eating and drinking. Tom and Sharon step in first and are greeted warmly with hugs and kisses on each cheek. The items they are holding are quickly offloaded and presumably on their way to the kitchen.

Jake's parents clear the door and Jake and you step in next. You expect them to hug Jake and give you a handshake or something you're used to with your extended family in Wisconsin. Jake holds out his arms to hug a lady about Sharon's age, and based on appearance you assume a sibling. You laugh when she completely bypasses Jake and engulfs you in a big smothering hug and kisses on each cheek. You see over her shoulder that Jake is pretending to be offended,

"So this is how it is now, Aunt Nancy, what am I chopped liver?" he says putting on his cute little mock pout.

"Jakey, you're old news, we all want to meet the girl that has captured your heart and got our wandering mustang to finally settle down," she replies, still looking at you.

"Elsa, it's so good to meet you. I'm Nancy, Sharon's sister. Sharon said you were beautiful, but you're a dream, and an aerospace engineer, with a PhD," she looks over at Jake, "You did good kiddo."

Jake steps over and takes your hand, "That I did, I'm going to introduce her around, we'll be back to chat, Nancy. I promise."

Tom has reappeared and hands you a gin and tonic, he leans in to say, "If you were anything like me, meeting all the Lucarellis all at once might be a bit overwhelming. This'll help."

You thank him before Jake leads you to the back of the living room where there is an older lady sitting in an armchair talking with a few people.

"Sorry to interrupt, but I thought Nonna would want to meet Elsa."

The older lady jumps up with surprising agility given her age. Jake has to lean down to speak to her, she is a little shorter than you,

"Nonna, this is Elsa, my girlfriend."

She wraps you in a warm hug and pulls back keeping her hands on your elbows,

"Nice to meet you dear, glad to have someone around here my size. It's like living in a forest of people."

"Nice to meet you too, Mrs. Lucarelli," you reply.

"None of this Mrs. Lucarelli nonsense, call me Nonna, everyone else here does."

"I've heard a lot about you from Jake, I'll have to thank you for Jake's cooking skills. He's made your pasta Bolognese recipe for me."

Her eyes go big and a large smile blooms on her face,

"Jakey, made you my Bolognese sauce, that's interesting, indeed."

She looks over your shoulder to Jake raising her eyebrows and continues,

"I was going let Jakey have it about making you an honest woman, but I see he's got that in hand. He's a good boy." She reaches up to pat Jake's cheek.

"We're working on it, Nonna, you'll be one of the first to know," he replies, before excusing us from the conversation.

"I'm going to go introduce Elsa around, we'll talk to you later."

One of the Aunts exits the conversation and she scampers over to where Sharon is sitting. She leans down to whisper something in her ear. She lights up with a big smile and you swear she is bouncing with joy at whatever she just heard.

Jake brings you around to meet some of his cousins, most of whom give him a hard time about finally bringing a girl round to meet the family, more aunts and uncles, and few more family members. It's a whirlwind of hugging, faces, and "nice to meet you's". Towards the end of the circuit people start to add on, bits of "he made you Nonna's Bolognese, interesting" or some variation on that theme. There's a few "Welcome to the family" remarks also. You finally make it through all the relatives and Jake pulls you aside into the hall where it is quieter and asks,

"How are you doing? The whole family thing can be a bit overwhelming with this clan if you didn't grow up in it."

"I'm good, I probably need a family tree with pictures and names on it to remember everyone, but everyone is so warm and welcoming."

"Good, just wanted to check in and see if you needed a break."

"Nope, I'm all good. What's with everyone making a thing of the fact you made me Nonna's sauce?"

There is a quick flash of something that could be described as embarrassment across his face.

"I'll tell you later, when we're alone." He drops his voice and leans in close to your ear causing you to shiver at the way he says the word "alone". Looking up with probably lust filled eyes, you just nod and walk out of the hallway.

You walk over to a pod of his cousins, and recognize one of them, Matt, who said he was a mechanical engineer.

"I'll leave you here with the other engineer while I go grab some drinks. The same, El?"

"Umm, no, I'll take a glass of red,"

you answer.

"Yes, Ma'am," he replies and heads off to wherever the drinks are in the house.

Matt and you chat about our respective engineering jobs while Jake gets the drinks. Soon he's back and the conversation keeps going and is lively and filled with laughter. People wander in and out of the group where you are standing, Jake's arm constantly around your waist.

You finally make your way to the kitchen when you feel your stomach growling. Every flat surface is covered in some kind of food, 80 percent of it Italian dishes. You count six crock pots on the counter, all plugged into an industrial looking power strip.

"Holy shit, your family doesn't mess around with the food," you tell Jake as you survey the scene.

He laughs,

"Yeah, no one's going to go hungry in an Italian kitchen, that's for sure."

"What's with the heavy duty hardware for the crock pots?"

"We blew a circuit breaker one year, so my Uncle Pat rigged up something sturdier, he's an electrician."

You are trying to not laugh,

"You realize that this isn't helping with any of my preconceptions of Italian families, right? Between the kissing on the cheeks, calling your grandma Nonna, and now this acre of food, wait, is that literally a pile of bread on the table?"

You giggle in glee.

Jake slightly rolls his eyes.

"Yes, that might be 10 loaves of bread from the Italian grocery in town, but it's what we do. Do not mock the bread. When you're done making fun of my heritage, I'll give you the inside scoop on what to eat out of this acre of food," he says in mock exasperation.

Grabbing a plate you follow him. Looking around to make sure no one can overhear him, he tells you in an almost whisper,

"Aunt Jilly's meatballs are the best," he points, "but I'll never admit that my mom's aren't the best. My mom does have a lock on the best lasagna, which is that pan."

You take a little bit of each.

"You can't miss Uncle Greg's pesto, he grows everything in his garden."

"Is that sauerkraut?"

You ask, its pungent smell coming through all the other aromas of tomatoes, garlic, and basil cloaking the table.

Jake sticks out his tongue in disgust, "Yeah, my Aunt Betty married a Polish guy, he insists on bringing it to every family gathering. It's homemade, which I give him credit for, but it's still sauerkraut."

"I like sauerkraut, so I will gladly have some," you reply, scooping a little onto my plate. Jake is aghast,

"I might be reconsidering this relationship at this very moment."

"Drama queen, it's the Wisconsin in my DNA, more German than Polish, it depends where the line was drawn when my mom's family left. You cannot beat a good bratwurst off the grill with German mustard and sauerkraut."

Now it's Jake's turn to laugh,

"That is so Wisconsin, can you say, 'You betcha or go Packers?'"

"You shush," you tell him with no malice behind it. You take a bite of the meatball, which is about the size of a baseball, on your plate. It is amazing.

"Okay, I concede this spread is way better than any brat grill out. These are so good."

He smiles,

"I have Aunt Jilly's recipe at home, if we want to cook it."

You find a place to eat and join the conversation. Ellie and Gigi come running through trying to steal goodies from the dessert table with a pack of their cousins. They give you and Jake a quick hug before joining their mission again. Finally, it seems that everyone has eaten and is chilling in the post dinner lull.

One of Jake's cousins, Paul maybe, calls out,

"Football time!"

A few groans come out of the crowd but most everyone in your generation gets up.

"What's going on, Jake?"

"We generally play some backyard football, to keep us from going into a food coma, you're welcome to join us."

"Sure, why not?"

Soon you're all assembled in the backyard and teams are being formed. Somehow Jake and you end up on opposite sides. The field boundaries are delineated with whatever the group can find to make a few corners. You look at your teammates and try to remember their faces. You all huddle and don't really make any strategy beyond score, before the huddle breaks you ask,

"Is this tackle or touch?"

"A bit of both, mostly tackle, but don't be an asshole about it," Mark, (you think) replies. You nod.

Your side has the ball first, one cousin hikes it to Mark and sees that you are open near the end zone and he sends a nice spiral your way that hits you right in the numbers if you were wearing a jersey and you run it in.

You stick your tongue out at Jake as you trot back to your team. He just gives you that trademark smirk and you know the next time he gets close enough he's going to say something that will leave you hot and bothered or flustered or both. Sure enough, just before the ball is hiked to the acting quarterback of his team, he leans over the line and says low enough for just you to hear,

"We both know what that tongue of yours can do, is that a promise for later?"

Before you can reply the ball is in play and Jake is running past you wide open to catch a pass. You catch up to him and attempt to tackle him around the waist. Your arms go around his torso as he catches the ball, but instead of falling down he just scoops an arm around your waist and pulls you upside down to him and runs the ball in for a touchdown. The rest of the cousins are dying laughing as you pretend to pout,

"Can you put me down now?" as you hang upside down with your legs bent at the knee over his shoulder. He laughs and holds his arm out and steady allowing you to rotate over it to your feet.

He leans over to try and kiss you, and you move your lips at the last minute to whisper in his ear,

"If you wanted to try some acrobatics in the bedroom, all you had to do was ask. I'm pretty sure I could suck your cock in that position."

You trot back to your team watching his face comprehend, imagine, and then try to clear the thought from his mind.

He looks directly at you with those piercing green eyes as the teams line up for the next play. You know he is coming for you on this play. Again you slip past the defensive line, or what counts as one for this game, and are open. Mark sends you another great pass and you catch it. Jake runs full out towards you, you lateral it over to one of your teammates and run towards Jake, causing a moment of confusion until you tuck and execute a perfect gymnastics tumble through his legs ending up on your feet with your hands in the air out of habit. Jake in his attempts to catch you slips and falls on the ground. Your teammates cheer the touchdown you assisted on. You walk over to Jake who is still on the ground.

"Are you okay, baby?" you ask leaning over him.

All you hear is a soft groan of what sounds like pain, you ask again,

"Are you okay, Jake? Say something."

He groans again and feebly raises his hand and crooks a finger for you to come closer and you lean farther down. Suddenly, Jake's arms snap up and grab you, pulling you down on top of him.

You squeal,

"No fair, I thought you were hurt."

"My pride is, it's not every day someone pulls out ninja gymnastics moves to evade a tackle while I end up on my ass."

"You liked it. If your ass is hurt I can massage it later."

"I'll hold to that promise later."

He lets you go and you help him stand up.

The football game breaks up as everyone filters into the house for more food and a drink. Jake and you are behind everyone else and you pull at Jake's sleeve to step out of the halo of the porch light. You wrap your arms around his neck and lean up for a kiss. He kisses back with just enough passion to not start something you can't finish till later.

"What was that for?" he asks, smirking, as he breaks the kiss.

"Can't I just kiss my boyfriend?"

"True, but you seem like you want to say something."

"I was just going to say, thank you for inviting me to Texas. It's been one of the best holidays I've ever experienced."

He runs his thumb across my check, "They're only going to get better from here on out."

"Promise?"

"I do," he mostly says inside the next kiss.

He starts to laugh,

"So, 100 percent chance that at least three of my aunts are staring out the window seeing what we're up to."

"Now I'm starting to feel embarrassed."

"Don't be, they're just a sucker for a good love story. Here's the brilliant part, is that if we turn around fast enough we'll catch them and they'll be more embarrassed."

You laugh and he says,

"On 3, I'll turn around and you can jump this way, 1,2,3!"

You execute Jake's plan and his aunts look like birds trying to escape a cage, two just give up and pretend that they were just casually talking by the window. Jake and you double over laughing, he takes your hand and leads you inside. The nosy aunts have scattered from the back door area by the time you enter the house.

The get together winds down pretty shortly after the football game breaks up. You help Sharon and Tom load up the car and say goodbye to everyone.

As you're saying goodbye to Nonna, she waves for Jake to lean down so she can tell him something,

"Next time I see you two, there better be a ring on her finger. Elsa, if he's hemming and hawing, give me a call and I'll set him straight."

You barely conceal your laughter and give Nonna a hug,

"Welcome to the family, Elsa. You can tell how much Jakey loves you and you love him."

The ride back to Jake's house is quiet and calm. All the good Italian food and wine is making you sleepy. It's about 10 pm when you get back and get everything unloaded. Tom and Sharon head off towards their bedroom and Jake and you climb the stairs to his room.

You walk in before Jake and flop on the bed, the day and the food making me very sleepy. The bed sags next to you and you roll over to face Jake.

"So what was the whole thing with Nonna's sauce?" you finally ask.

He laughs,

"It's a family tradition, maybe superstition. When I learned to make it Nonna said it was a very powerful recipe and to only make it to catch the person you want to marry. She said, 'It worked for me, your mom, and all her sisters and it'll work for you. This goes back generations of happy marriages.'"

"You made me your Italian grandma's magic marriage sauce on our third date?" you ask, incredulously. Jake's face blushes a little bit as he takes your hand.

"Yeah, I knew I was feeling something I hadn't felt before and you are a once in a lifetime kind of woman, to quote Maverick, so I thought if Nonna's special sauce could help why not try it."

"You are such a closet romantic"

"Only for you, babe, only for you."

"You are a once in a lifetime man, Jake Seresin. A once in a lifetime man that I would like to cuddle up with and go to sleep with."

"That sounds like an excellent idea."

The last thing I remember is the soft kiss Jake gives you on your forehead.

He really had no idea where things had gone wrong.

It should have been simple. He was eighteen, responsible, head of his class, and excelled in leadership challenges. He was a top-of-the-line Rescue Scout, he had all the badges. This should have been easy.

But it wasn’t.

It had been Virgil’s suggestion. Though more correctly a Gordon-suggested-Virgil suggestion. Scott would have much preferred a trip out to the local airstrip and John had made it very clear that he would have rather visited the local space centre.

But Virgil had pulled the ‘we always do aerospace, this is unfair to Gordon’ card. And the annoying thing was that Virgil was right. Gordon usually got the short straw in group activities because his interests lay in different areas to the vast majority of the family.

He did have a powerful advocate in Virgil, though. Fully capable of poking every button Scott had to get his way.

Younger brothers may be everything, but damn they could make life difficult.

Maybe the fates had sent this one as a learning experience.

He stared down at the chicken currently perched on his knee. It was one of the fancy breed types. Small, fluffy, barely able to see beyond the end of its beak, and exactly the perfect size to fit in Gordon’s pocket.

This wasn’t an empirically tested fact, but Scott could not work out how else his little brother had smuggled it out of the petting zoo. Perhaps he should be glad it hadn’t made it out of the actual zoo and onto public transport, or, god forbid, back to the hotel room…and Dad.

He was trying not to think about Dad too much right now, because explaining this was likely to get them all grounded until Scott had as much grey hair as his father.

Though at this rate, that might not be too far into the future.

“Scotty, can I have an ice cream?”

He turned to look at his tiniest brother and was assaulted by his big blue pleading eyes.

This was seriously not fair. His brothers had weapons like this that Scott had so much trouble denying. “No, I’m sorry, squirt, we have to stay here until the Zoo Manager comes back.”

“But I’m hungry.”

Gordon, still dripping wet, on the other side of Scott, poked his head around. “Told you, you should have eaten all your lunch.”

“Shuddup, Gordy.”

Hmm, maybe Scott had said that phrase a few to many times if Allie was picking it up. “Gordon, I wouldn’t be saying anything right now if I were you.”

“Hey, it wasn’t my fault.”

“Then whose, exactly?”

“I was saving Frilly! She can’t swim!” As if to emphasise that fact, the chicken on his knee fluffed up its feathers and flicked water in his face.

He closed his eyes and wiped a hand over his eyes. “And who exactly endangered Frilly in the first place?”

“She wasn’t in danger! I was protecting her!”

“By stealing her from her home?”

“Scott! We have a farm where she can play and be happy.” Gordon screwed up his face. “Not be trapped in that horrible cage.”

“Gordon, we have been through this. She is well cared for.”

But his little nine-year-old brother folded his arms over his chest, screwed up his face into a massive grump, and turned away from Scott, conversation ended.

Water dripped silently onto the wooden bench.

“I want an ice cream.”

Scott closed his eyes and sighed.

The chicken pooped on his jeans.

-o-o-o-

Perhaps it had been a bit much to ask of Virgil. His younger brother had spent most of the year eyebrow deep in his studies. It couldn’t be easy having John the genius waltzing through several subjects enough to catch up and then having to work alongside him to get final grades. There were three years between Virgil and John, but John was quick, and while Virgil was his own kind of smart, it didn’t equate academically to Johnny.

Virgil took it well, but Scott, while proud of both his brothers, knew it couldn’t be easy for the elder of the two.

So if Virgil had been distracted enough for this to happen…

No, that wasn’t fair. This was Scott’s responsibility and he trusted Virgil with everything.

When Alan had wandered off and disappeared, Scott had no issue with leaving his other two brothers under Virgil’s care while Scott tore through the zoo trying to find the missing three-year-old.

There had been announcements over the PA, staff alerted, and a hunt.

Apparently, while Scott panicked - yes, he would admit to himself that his response was a little haphazard and, if he was honest, frightened - Virgil had chosen to distract their two youngest brothers by taking them to the small aquarium.

After all, Gordon adored aquariums. Good decision. Excellent choice.

Perhaps not so much.

By the time Scott located Alan, who had somehow hitched a ride on a tour buggy that had disappeared into a jungle exhibit, both Gordon and Virgil were soaked to the bone, and John had been ‘arrested’ by zoo staff.

Hugging Allie to his chest, not sure he ever wanted to let him go again, Scott had walked into the aquarium to discover chaos - with his three brothers at the centre of it all.

John was the biggest surprise, really. His middle brother was the academic achiever, smart and more inclined to spend time with himself than hordes of friends.

But then they do say it is always the quiet ones.

John had dismantled a holographic sign, re-coded it and changed the display.

“What the hell? Why, John?”

Showing zero remorse and if anything, disgusted that he had had to go to the effort, his brother replied, “They were disseminating incorrect information. That was not a Leafy Sea Dragon, it was a Weedy Sea Dragon.”

Scott had stared at him for a full moment. “How the hell do you know that?”

John rolled his eyes. “He’s my brother, too, you know.”

And then he’d been mobbed by zoo staff demanding to know how to fix whatever it was he had done.

That left Virgil.

Who had fallen into the central aquarium itself while trying to get Gordon out of the water.

Did Scott love his fishy brother?

God, yes.

Did he want to throttle him?

There was a strong possibility.

Virgil could swim, of course, but it had been an aquarium with other denizens of the sea in there with him and while Gordon was quite happy chasing stingrays and sharks, Scott completely understood Virgil’s not so positive reaction to sharing marine real estate with them.

There may have been a little too much water swallowed and so much coughing afterwards that the zoo staff had called in their medical team.

Yes, Scott could feel a grey hair popping up through his scalp right about now.

Virgil’s apologies kept being cut off by his hacking cough.

So here Scott sat, a little brother either side of him, a chicken on his knee, one brother getting the third degree from the zoo technical staff, the other being given oxygen just in case he hadn’t finished drowning.

Scott’s brother radar was pinging in so many different directions he was at a complete loss how to respond. This was a new experience.

He always knew what to do.

But apparently not now.

So the sight of his grandmother walking through the door set off such a wave of relief he nearly went down under it all.

“Grandma!”

“Honey.” And he was wrapped in her arms, the chicken taking flight as he stood up, and two little brothers jumping in to make it a group hug.

She stroked his hair.

“Thank you for coming.”

“Always, honey.” She pulled away gently. “Now, get me up to speed. I need a sit rep.”

He stared at her.

Both the chicken and Allie were attempting to climb his legs.

So Scott Tracy straightened up, reported in detail…

And handed the situation off to his superior.

Grandma would know what to do.

The Importance of Aluminium Ingots in Various Industries

Aluminium is a lightweight and versatile metal that is widely used in many different industries, including construction, automotive, aerospace, and packaging. Aluminium ingots are an essential part of the manufacturing process for producing high-quality aluminium products. In this blog, we will discuss the importance of aluminium ingots and their use in various industries.

What are Aluminium Ingots?

Aluminium ingots are rectangular or trapezoidal blocks of pure aluminium metal that are used to produce various aluminium products. They are produced by smelting raw aluminium ore and then pouring the molten metal into a mould. Once the metal has cooled and solidified, it is removed from the mould and processed further to create a wide range of aluminium products.

Uses of Aluminium Ingots

Construction Industry: Aluminium is widely used in the construction industry due to its lightweight and corrosion-resistant properties. Aluminium ingots are used to produce various building materials such as window frames, roofing sheets, and structural components.

Automotive Industry: Aluminium is also extensively used in the automotive industry due to its lightweight, high strength, and durability. Aluminium ingots are used to produce car parts such as engine blocks, wheels, and chassis.

Aerospace Industry: Aluminium is a critical material in the aerospace industry due to its lightweight and high strength-to-weight ratio. Aluminium ingots are used to produce aircraft parts such as wings, fuselages, and landing gear.

Packaging Industry: Aluminium is widely used in the packaging industry due to its excellent barrier properties and ability to preserve the freshness and quality of food and beverages. Aluminium ingots are used to produce various types of packaging such as cans, foils, and containers.

Advantages of Using Aluminium Ingots

Lightweight: Aluminium is one-third the weight of steel, which makes it an ideal material for applications where weight reduction is crucial.

Corrosion Resistance: Aluminium is highly resistant to corrosion, which makes it ideal for outdoor applications and harsh environments.

High Strength-to-Weight Ratio: Aluminium has a high strength-to-weight ratio, which makes it suitable for applications where high strength and low weight are required.

Aluminium ingots are a critical component in the manufacturing process for producing high-quality aluminium products. They are widely used in various industries such as construction, automotive, aerospace, and packaging. Aluminium offers numerous advantages over other materials, such as its lightweight, corrosion resistance, and high strength-to-weight ratio, making it an ideal material for a wide range of applications.

College Kim and Ron headcanons I have:

- They both attend the same college, Kim ends up pulling strings to get Ron in because it's a prestigious one in Upperton but because he's helped save the world all his lackluster performance in high school doesn't really matter too much in her eyes and she's able to convince the administration (she has no problem getting into there of course since she graduated with high marks)

- because of the above, Ron is much more motivated to do well academically since he's afraid of getting kicked out + Kim gives him an incentive to excel at his studies, he does falter at first a bit but is able to bounce back just fine

- I'd like to think Barkin ends up becoming a transient instructor at the college and this is initially a shock to Ron but he's able to get over it and even gets on his good side

- Kim double majors in aerospace engineering and biology so she has a little of both of her parents' careers under her belt, her professors are okay with her doing the saving the world thing unlike in high school but she's able to fit her studies in with all the traveling and finds some ways to tie it into coursework

- Ron also probably double majors in business and IT/fintech or whatever so he can take over Bueno Nacho and flex on Wade or something like that

- They room off campus, neither of them wants to deal with dorm life and just want to be together

- Of course they have their Friday nights together like back in high school but this time it usually ends with them cuddling/spooning on the couch, also occasional romantic dinner dates

- Ron doesn't join the football team in college, he just takes up running for a side activity and hits the treadmills at the gym from time to time, Kim also goes there to do some weight training/yoga and gets Ron in on it

- Maybe for a short while Kim goes back to Middleton High to coach the cheerleaders there since she kinda misses it + checks on the tweebs to see how they're doing academically

End Of An Era: A-10C Thunderbolt II Demo Team Announces Final Airshow Season

The A-10 Demo Team has just announced their farewell tour 2024.

David Cenciotti

A-10 Demo Team Farewell Tour 2024

The U.S. Air Force A-10C Thunderbolt II demonstration team is the unit in charge of highlighting the A-10C’s capabilities during airshows across the United States and to recruit, retain and inspire the next generation of Airmen. The team will perform its duty for one last season this year: in fact, as announced on social media, 2024 is going to mark the final airshow season for the Warthog demo.

The farewell tour does not come unexpected though: last month, the 355th Wing at Davis-Monthan AFB, Arizona, where the Demo team is based, begun divesting its fleet of A-10 aircraft after nearly 50 years.

The first model of the aircraft to arrive at Davis-Monthan was an A-10A on March 2, 1976. This model was assigned to the 355th Tactical Fighter Wing that arrived here in 1971 and replaced the Vought A-7D Corsair flown by the 355th TFW. The 355th TFW was later reclassified as the 355th Tactical Fighter Training Wing, prompting the 354th, 357th, and 358th Fighter squadrons to train U.S. Air Force Pilots on the A-10A aircraft.

A-10 Demo Team

The heritage paint scheme of the A-10C Demo Team, introduced for 2023 season.

The U.S. Air Force has plans to divest the entire fleet of A-10 aircraft within the next 3-5 years, when the iconic jet will be replaced by the F-35.

“The A-10 has been the symbol of Davis-Monthan Air Force Base for many years, and it will continue to be a symbol for the Airmen of DM, a symbol of their commitment, excellence and service,” said U.S. Air Force Col. Scott Mills, 355th Wing commander and A-10 pilot in a public statement. “For now, we’re divesting a single squadron during the summer-fall timeframe of 2024.”

Coinciding with the divestment, Davis-Monthan plans to expand its Rescue Footprint, which may lead to additional utility of the HC-130 aircraft and the HH-60W helicopter. Airframes expected to arrive from the Air Force Special Operations Command include the MC-130 and OA-1K.

A-10 Demo pilot

Capt Lindsay “MAD” Johnson, Demo Team Commander, poses in front of her aircraft.

“From an Ops personnel standpoint, this divestment arguably allows a more expeditious stand-up of the F-35, even as that program continues to struggle with a variety of delays,” said U.S. Air Force Col. Razvan Radoescu, 355th Operations Group commander.

The aircraft 82-648 was the first to be retired from service at Davis-Monthan on Feb. 6, 2024, and transited from the 354th Fighter Squadron to the 309th Aerospace Maintenance and Regeneration Group for final maintenance procedures and display preparation for the Davis-Monthan where hundreds of retired Aircraft are stored.

“There will always be a job for maintainers; it may not be on the A-10, but the Air Force needs maintainers to sustain airpower,” said U.S. Air Force Col. Clarence McRae, 355th Maintenance Group commander, “Perhaps the biggest draw of future maintainers will be in the F-35 community. Airplanes are still going to break, and we are still going to fix them.”

One of the memes that you could find online during the early days of the Ukrainian invasion by Russia.

Anyway, there’s still time to attend an airshow and watch the A-10 Demo Team, commanded by Capt Johnson, an Instructor Pilot and Flight Commander assigned to the 357th Fighter Squadron, Davis-Monthan AFB, Arizona and previously served also in Texas and Korea, at her second season as the commander of the team.

Here’s the schedule.
