Sounds like exactly the thing to make the parts I want to mill much easier to get into computer land than painstakingly measuring and CADding. Put the original on a scanner, scan at crazy high resolution then use Photoshop to edit the image to feed to potrace. Then use that outline to loft into 3D. The original item is 3/4" thick with a thin extension on one end, with a rounded fillet for strength. The back side of the original is hollowed out with some webs, die cast, breaks often. I've been making spin cast Zamak copies but they also break, wasn't things like FEA in the 1940's. I figure solid CNC milled aluminum or steel should make the part indestructible, also much safer. ------------------------------------------------------------------------------ Everyone hates slow websites.
