Depth measuring base for a caliper gauge

[xynudu]

Hi Paul,

I wondered how many would pick up on that - you're the first.

While it allows precision advancement of the carriage, it also has several other important benefits:

- It prevents the mill slide from canting back, as you apply all pressure at the centre spindle line of the lathe.

- It reduces chatter as the mill slide is braced at the back/centre line.

Advancing the saddle with the carriage hand wheel is not a good idea, for all of the above reasons.

Cheers Rob
