Definitely. Thank you for the link. And I thought I'd seen all of the YouTube vids on the subject.
I'd already considered a scale along the toolrest, but hadn't thought of using a guide clamped to the scale or a depth gauge attached to the tool shaft.
I'll have to think about how to incorporate his tricks into my method. Wish I had a welder to make a custom toolrest.
It crossed my mind that it'd be easy with a compound slide, too, but sort of cheating.
Edit: Trust the Germans. They have engineering on the brain from the moment they're born. All of the best engineers I've ever known have been German.
