Shopmade cam clamps made from scrap 3/4 inch stock after a Fine Woodworking article, and several YouTube videos. The maple bodies are pinned to 1 inch by 1/8th inch aluminum bar from the hardware store on the fixed ends with 3/16th x 3/4 roll pins. Some designs do not fill the bottom slot but rely solely on roll pins to bear against the bar on the movable jaw, but I had a hard time placing the pins to tight tolerance and decided to infill the mortise. I added the decorative hardwood scales in walnut, jatoba, striped mahogany and lacewood to dress them up a bit. Jaw faces are just chunks of cork craft tile as used for bulletin boards etc. The movable jaw is retained with a Pop Rivet.
Finish is BLO/MS/Alykd varnish wiping oil.
I was able to make four sets; two long and two shorts from the 4 foot aluminum bar and a handful of roll pins, total outlay of about $15.00. They are light duty, but handy and quick to set.
