Continuing the discussion from My first serious win with the Form1+:
I built this a while back from a couple of loaf pans, a makita palm sander and some 2-part expanding urethane foam, separating the foam chunks with saran wrap when casting. I drive it with a router speed control. Totally kicks ass and cleans the part completely in a couple minutes.
I do a quick rinse first in the static IPA container, then drop it in the loafinator, change up the vibes a bit for fun, and let it jiggle for a couple minutes. Then I take out the part, dry it off with my air compressor, and throw it in the UV box.
The base poured, saran over it, then hold the sander in place level until it kicks.
Front chunk poured.
Back chunk poured.
top chunks and sander removed from pan. the form got kinda hot and some saran wrap was really stuck to it.
Almost done in this pic. Now it's been epoxied to a slab of baltic birch plywood with rubber feet, but I still have to clamp it to the workbench
I'll try to post a video of it action next time I use it. It really screams!
