I've been thinking about mounting a dial indicator on my lathe cross slide for some time now, but just never got around to it. Well, I finally did it, and all I can say is, "Why didn't I do this earlier"! I makes it so much easier to determine how much metal you're taking off or how much you are increasing the bore. Cross slide movements of half a thou can be done done now.
The bit of metal that engages the anvil of the indicator is a clamp bar from one of my fixture plates. I can easily reposition it with a wide range of movement to bring the indicator to zero and/or accommodate different size turnings. The holder bar is made from 1/4" aluminum and is also slotted where it mounts to the carriage so some range of adjustment is available there, although I doubt I'll ever need it.
If you don't have one of these, make one quick. You won't be sorry!
