ER32 Collet Chuck for Proxxon PD 400

Thanks Dave, but expert I'm not and will not be.

I thought about how I should measure the register. My plan is to have the centre hole done after cleaning up the other side. From the hole, I'll face outwards and stop to measure with the caliper. Once I established where I'm on the 70mm dia recess, I can continue to open up the recess using the dial on the handwheel.

Is that the right way?
