It was a slow Saturday in the shop, so I decided to teach students a little about manufacturing processes. I started off by explaining why C-base isn’t actually traditional C-Channel. Basically the fact that regular C-Channel is extruded, and C-Base is lasered sheet metal formed in a press.
Then I shifted into strength of materials and how we are looking to plastically deform the aluminum, but not pass its ultimate strength. Basically a poor forming die design can become a shearing die design.
Then I decided to whip up a demonstration, so we gathered supplies from our empire of dirt, and we whipped up our very own forming die that fit into our horrible freight 12 ton press. It wasn’t the most skookum die made out of wood and aluminum, but it was a relative success for being a proof of concept.

I don’t think you will see us competing with andymark any time soon.
