I'll be interested to see how this goes. For ages I've had the wish to make a batch of stainless steel Kant Twist clamps for use in my wire EDM machine, where the de-mineralised water electrolyte is too aggressive for mild steel.
They only need to be relatively small, and the clamping forces minimal as the cutting pressure is practically zero.
Got the plans, could order the stainless, but my get up and go seems to have got up and gone !
