Face Plate Clamps
I then chamfered it for aesthetics, and parted it off using the rear tool post with an inverted cut-off bit.
An off center screw is needed to level the clamp while in use. I simply scribed a mark with a compass on each of the 3 clamps and drilled a 2.5mm hole in each using the drilling pad in the tailstock. I tapped these holes with an M3 hand tap. To fit these, and I made several M3 set screws from 3mm O1 drill rod, and cutting a slot with a screwhead file. This seems like a good time to show the Cowells thread cutting setup. The die holder is bored to have a smooth fit the tailstock 'spindle,' and has a tommy bar for assistance in cranking the die. With a little 'TapMagic' the threading is done with little difficulty.
I machined some nuts from 3/8" - 360 brass rod so that they can fit into the faceplate slots. They are simply tapped M5x0.8.
