@open_erv This is a part of a larger project I'm working on involving commercial-scale recycling of waste electronics, so safety & environmental responsibility are an important aspect.
Most days at the Makerspace I’m hammering something out of steel. Today though I’m scrapping this pile of electronics to harvest all the bits with gold and precious metals. Once I have enough, I’ll be doing a big gold recovery project! Stay tuned!
@open_erv Some of these electronics were fairly old, so likely do contain some lead. I'm planning a wet chemical process for this project, so the lead and tin will be recoverable in addition to the PGMs.
Oh my gosh, someone donated a box full of MASSIVE bearings to the Makerspace! Look at the size of these rollers. 52100 is one of my favorite steels to work with, so I had to immediately bang out a quick slicer.
Today I’m taking a break from whacking stuff with a hammer and instead boiling stuff in acid!

Damascus billet progress:
1 - Layers test etch/preview
2 - Initial billet cut and restacked
3 - Tacked up and slathered in flux slurry
4 - Forged out and almost ready to twist
A friend gave me pieces of her canister Damascus experiments to work with. They were too thin to do much with on their own, so I added more material and am forging a new billet. This is 6 layers of canister Damascus, 3 layers of coil spring, and 10 double layers of bandsaw blade.
Hello friends, the Milwaukee Makerspace is holding an auction to raise funds for the wood shop!
If you're not in Wisconsin but want something here, get in touch with me once you've won your bid(s) and I'll ship it out to you.

@open_erv They typically make very tough knives, as they are usually 5160 steel (or an alloy in than neighborhood).
The grain structure was good and tight; it broke because I was trying to bend a warp out of the blade as it came out of the oil quench. ;_;
This was going to be a chef knife for a friend, I forged it out of an old leaf spring from a car. But I broke it after the quench.
Crap. Time to start again.
