Welcome to Arduino
I have removed the gears and set the motor on top of the vertical tube. I am going to have to counterbalance the cross slide, probably with a gas spring in the tube.
If you can find one Montgomery Wards sold a saw with a 30,000 rpm aux spindle for routing. I have one I am planning on doing the same thing with. I am using the depth control screw for the Z axis.
When you quench copper it works best if you lower it into the water on edge.I don't know why but that is how we anneal copper head gaskets.
