I was inspired by Ecocandle’s planing board http://lumberjocks.com/projects/33258 The cam that functioned both as a stop and a clamp is very clever. I got thinking about using a pair of similar cams to hold smaller pieces for planing.
If you have 3/4” dog holes on your bench already then you should see some potential for having one or a pair of cams to hold pieces for planing. The best part is I can plane a side, grab the part with one hand, flip it over and plane the other side without having to loosen and tighten my vice. It makes for pretty fast work.
These are made with 7/16” plywood (so I can plane to 1/2” without digging them up) and 3/4” oak dowel. After I use these a bit more (to find any shortcomings) I will probably make a pair out of 1/4” plywood or hardboard so that I can use them while planing thinner stock.
Each cam has a stopping arm (that the end of the board runs into) and a clamping arm, that pushed the face against a dog, stop, or the other cam. The only major feature I found in my planning (using cardboard models) is that the pivot point needs to be closer to the stopping arm.
