Hand Screw Clamps

[Guy Gadois]

I needed some clamps able to clamp irregular shapes so I made these. This type of clamp requires both right and left hand threads. The most difficult part of the project was tapping and dieing (is this a word?) the left hand threads. I have seen other small clamps being made on youtube but they get around using left hand threads by using nuts or copying the machinists clamp.

Cheers, Guy
