2) I really like the ability of a digital mic to be set to the desired dimension and zeroed out. That way, I can check a diameter on the lathe and read the ammount of material left directly. This really helps avoid silly math errors, especialy when trying to hit a metric diameter using inch dials.
I hope this helps
Reading this point was a DUH! moment for me! Makes all the sense in the world. Why didn't think of that?????
