Thread: I Found It Over There

you could always build one Rezdog.

Or even better build a power hacksaw.

The power hacksaw is an arcane outdated and very simple tool. A motor drives a cam that pushes the blade forwards and backwards and the whole assembly is on a restricted dropping mechanism. You have a vice to hold the rock, and the whole unit can be immersed since all the drive is done on a belt and pulley system. You could almost scrap one together, provided you had a motor and a welder. As for the blades you just use the tungsten carbide 300mm ones and steal the puller from a hand hacksaw.
