I too have a good body clock, excepting for a few weeks every Spring and Autumn, when the Politicos tell us that time must alter by an hour.

I have an irritatingly accurate body clock. It's not getting a lot of use as the puppy is running 45 minutes fast

> I don't have a lathe DRO but do you set the cross slide one to show zero at centre and do the maths or do you zero it on the current diameter so you can 'dial in' a particular depth of a shoulder?

It surprises me how few people do this, especially with digital callipers.

I set my digital calipers to the final dimension I want, then zero the display. Then I take a skim of the work piece with the cross slide dial set to zero and measure the resulting actual diameter of the work with the calipers. The indicated distance tells me directly how much more diameter I need to remove. When the work piece is reduced to the point that the calipers display zero, I'm there.

My Bantam cross slide dial measures directly in mm diameter increments, so I can now dial in the required additional cut directly. If I'm feeling paranoid, I can take several cuts and confirm that I am approaching the final diameter from above by using the calipers after each cut.

I normally work in mm but if the diameter is imperial, I set the required imperial diameter on the calipers, zero it and then swap over to metric display.

If I had a "radius" indicating dial, I'd have to take my chances at halving the number between the caliper display and the cross slide dial. Halving numbers is something I can still usually manage but it doesn't arise with the Bantam.
