For several years, I have built cars for Toys for Tots. Each year it seems I add another jig to do an operation. The bodies are shaped like a Volkswagon, so they are easy to sand on disk sander. Except the area where the windshield meets the hood. Last year I made a jig to hold bodies, while I sanded this area. When unpacking, I looked at jig and couldn't remember how it worked. It's just a couple of pieces of wood attached to a piece of plywood, and FOUR SCREWS, for what I couldn't remember:icon_scra. To sand bodies, I had to hold body in one hand, and sander in the other. In just a few moments both hands were numb:gar-Cr. Took a break, came back and did some more- repeatedly. On about car number 95 (out of 120), the STUPID LIGHT came on:BangHead:! The four screws hold a toggle clemp like is on a Kreg Jig. This way, plywood is clamped to bench, and car body is held in place by toggle clamp, while sanding. Gotta figure out how to get the delay function out of my stupid light- it comes on TOO LATE!
