Dovetail cutter???

I should have said "quill".

Everything on this mill/lathe is crudely [Chinese] machined. One graduation of the 'quill' handwheel dial should be .040" according to the chart. But my dial indicator says .037".

But it's not the mill/quill I'm talking about. It's the dial calipers. The digital calipers is consistently .010" off in measurements under .100", compared to the mechanical calipers . Zeroing doesn't help. And I can't get consistent readings with the mechanical dial calipers. Starrett calipers.

Can't pin down the problem. The dial indicator method works pretty well for measuring the depth of cut, but trying to get a consistent measurement of say a front sight base is fairly unlikely.
