Side view of a cam clamp. Note that the wood blank does not rest on the surface of the table. The two flat washers keep the clamp elevated off the table.
The finished product(s). The view of the right shows the hardware used to attach the clamp to the t-track on the DP table.
The hardware for one clamp includes:
1) 5/16 T-bolt
2) Two 5/16 flat washers
3) Two 1/4 flat washers with ID drilled to 5/16.
4) A short piece of hardwood dowel sanded...
One of the cam clamp blanks. I laid out the large and small circles on the ends of the blank using the OD and ID for a roll of pipe tape. High tech, I know.
