I need to find a way to sand these parts with more efficiency. Automated solution preferred. Pictures labeled 1 are prior to sanding, picture labeled 2 is after sanding. So as you can tell the finish does not have to be perfect, I'm just trying to knock the corners off and round the edges. Currently I'm using a flap sander. With the size of the pieces, this is taking just too much manual effort. I need to sand about 50-100 pieces at a time. The pieces are 1/8" to 1/2" thick.

Any ideas?Attachment 384660Attachment 384662
