I need to clamp a 3/4" square x 1/4" thick insert into a tool. The insert will have to be clamped by it's edge. It's supported on thebottom and on one side and the clamp will be on the third side. Picture the insert standing up on it's 1/4" side. My question is how much interference should the clamp be squeezing the insert? I'm thinking about 0.005". It's easy to increase the interference by grinding the holder back but a bitch to make it longer. The insert will be subject to a LOT of force and can't move! (Yep, it cuts flat wire like a guillotine.) I designed the cutter arm with the kind advice of people here...regardless of politics!
