well, it’s been a while that I posted anything that I did up myself due to being busy. Lately, Ive been just working on my cnc machine parts slowly, and working on a foundry and melting down aluminum cans and such, which the cans take forever to actually melt enough to cast anything useful. I need to get the stuff welded up on my foundry so I can really cast some larger stuff, or get enough melted to do so, but for now, just testing my homemade refractory mix, Im just using two coffee cans, a stainless steel pipe from an old broom handle that was broken, and a computer fan/blower. It seems to work pretty decently after the lid is put on. I just use this charcoal that we found in the trash, and it seems to really work good after it gets started.
I wanted to get some of the soda cans and old computer heatsinks, and whatever else aluminum I run across into something that I could fit into my little crucible, and I hate doing the generic, so I designed alternative looking ingots instead of the generic gold bar, angle iron, or cupcake ingots that everyone else uses. Instead, I designed these wooden/plastic blocks that I just cast in the greensand, so I can get practice with casting stuff, and these are the ones that I came up with:
Giant metal Legos! They’re 3 1/2″ x 2 1/4″ x 1 1/4″ in size, and they stack pretty easily into a small space rather than old pipes and cans. After I get a few made, Ill work on casting the mounts and such for my cnc machine and other projects where strength and where there will be a bit of heat, and the plastic will melt or deform. For now tho, Ill probably just be making my ingots and saving them for a non rainy day 😛
