    I'm not CNC conversant, but why do you need the ER collet extension at all? Or the tiny end-mill. Couldn't you make the same tapered cut with a 1/2" endmill choked-up directly in your live tool...

    +1 to Tommy1010's suggestion of a tailstock DRO.

    Simple aluminum split-collar on the ram. Cheap 8" caliper with one jaw fixed to the split-collar and the other fixed to the tailstock housing.

    Some great early examples.

    I seem to recall an early(ish) American example of a Black and Decker that looked like similar vintage to Cyanidkids examples in the Baltimore museum of industry.

    Thanks both of you. I love the soft dowel idea. I’ve got pitch gauges, just couldn’t see them inside the bore. That’s a perfect solution.
