There's a saying in boat building and in woodworking in general you can never have too many clamps. The truth is it's not the amount of clamps you have but the variety of clamps. Recently I was looking through a Wooden Boat series book on planking and in there there was a chapter on "Clamps in the Boat Shop" and a section about cam clamps. So, in this tool making episode of the Art of Boat Building I will build 8 cam clamps in the Klemmsia style.
