Rod Clamps...

The Prusa Mendel has the simplist of rod clamps, a good improvement on the original Mendel design. But faced with which type of clamp I could make more easily with 'stuff' to hand, I reverted to mimic the original design.

I routed two 8mm slots, 8mm deep, in what was left of the oak floor board. It would have been better to use a round-nosed 8mm bit, but didn't have one to hand.

Back to the chop-saw to cut to length 35mm.

Rotate through 90Deg, push against the stop and cut again to square.

There you go! A hole in each corner to take a nut and bolt of choice and I have a set of clamps.
