Soldering is hand sewing for electronics and hand sewing is soldering for cloth. The bandsaw is the sewing machine’s evil twin (rends instead of mends; but has almost the same user interface). In this essay I will
I’ve been a welder/machinist for 6 years now and I’ve listened to Les Mis at work since day one. If I’m not listening to some smutty fanfic, there’s a big chance I’m singing One Day More like I’m on broadway. This is the image it brings to mind. Super niche. I always picture the women in my shop with me. It makes more sense than it should
Learning about cowbutches. Incredible. 10/10. However I feel like there could be a related category. Machine shop butches. Every day I put on my safety glasses and steel toed boots to work with big machines. Are girls into this, I feel like they could be. (The machines can kill you btw.)
I just finished mounting this cute 80mm 3 jaw chuck on a W20 arbor for my lathe. The chuck is concentric to the arbor within 0.02mm which is not amazing but is better than the concentricity of the chuck itself so it’s fine.
Having it on an arbor is more convenient than a backplate and allows me to use it in my indexing head.
I also made the very badly finished chuck key pictured. I couldn’t be bothered to mill the square head so I just used a file.
Coming to you from inside the bottled parmesan factory, I bring you an exclusive look into how the powdered parmesan you know and love is made. In the video below, we can see a parmesan tube being shredded into much smaller and more manageable pieces. These pieces will then be further ground down into a fine powder, dispensed into bottles, and shipped to a store near you.
(Video description: A PVC tube getting coped in a tube coping machine. Small shreds of PVC are collecting in a tray below the end of the tube. The PVC shreds kind of look like shredded parmesan.)
I forgot to post these due to trying to keep it a surprise, but here’s the ka’rta beskar ornament I made for my riduur @withercrown for Christmas 😍
Steel alloy of some kind (pulled from the scrap bin hahaha) on a DMG50 5 axis mill. I drew it in CAD, pulled the geometric points, and wrote the program by hand. Took about four hours start to finish!
Filed and engraved a tiny d20 (specifically a fortuna dice). The 1 is the cosmosdex logo and the 20 is the fortuna chest. It’s around 6mm between flat faces and was absolutely a huge pain to make, but I’m quite proud of the result. Especially proud of all the numbers.
The tools clamp in there, and i have to clean the tapered part of the hole. Im so not normal about doing this every morning before starting the milling.
Mechanical systems in which moving parts come into regular contact are prone to damage due to the effects of friction. Researchers at Tohoku University have developed a contact control system, driven by artificial intelligence, to greatly reduce contact with damaged areas. Although currently tested only in lab experiments, they believe it could eventually help many types of machinery run more smoothly.
"This could shift the design strategy of mechanical systems away from the traditional approach of developing new and superior materials to developing surfaces that can actively adapt to reduce the damage," says Professor Motoyuki Murashima.
The work was a collaboration between Murashima at Tohoku University's Department of Mechanical Systems Engineering and colleagues at Nagoya University and the Korea Photonics Technology Institute in South Korea.
The research is focused on the potential of innovative materials possessing 'morphing surfaces', which can be changed depending on the environment they operate in. These materials are being developed by several research groups to mimic a common flexibility found in living systems, such as leaf surfaces that change in response to variations in humidity. One example in engineering, previously developed by Murashima and colleagues, is a surface composed of a diaphragm supported by hard substrate, with changes in stress pressure altering the surface morphologies.
