A toggle clamp for a jig, part 1 of 6: The four parts

A toggle clamp for a jig: the whole project

A toggle clamp for a jig, from a blank drawing to two working clamps and a plate ready to cut. The four parts are drawn from the side as rectangles and slots with typed sizes and welded where two shapes make one part. Four clicks pin them into a four-bar linkage that is pulled by hand; stops on the link make the lock, and a spring under the pad shows it: short of center the clamp springs open, past center it holds. A fence in the handle's way is found with Check for hits and moved with the Clearance tool, the pad's path is traced, the spindle is stretched for thicker work with its dimension following, and the whole clamp is copied, joints and all, onto a second plate. The plate is drawn from above with mirrored holes and checked for cutting.
