crank, I am not disputing your math in regards to total force, but the assumption that the clamp is only providing 1050 pounds of force. The clamp is providing 1050 pounds of force per square inch. Lets say you have 3 12 inch wide boards pressed together. The clamp optimum is in the center which is providing 1050 pounds per square inch of force. Wouldn’t you now have 37,800 (edited due to poor math) pounds of force applied?
