No, it's not another gun, I got one of those about a week ago. It's a DRO (Digital Read Out) for my lathe. I've been waiting a month and a half for it. It's an Igaging that I ordered from KMS Tools in Calgary. It gives my new lathe digital readout capability to a half thousand on an inch on both the X and Y axis. I didn't want the Chinese stuff, so I opted to wait it out for American gear. It doesn't make the lathe more accurate, that is a function of the lathe itself, but mine is wicked tight and accurate. It allows me to not have to squint my eyeballs to look at the thimble on the wheels, instead I get a nice accurate digital readout that I can switch from decimals, to fractions, or metric should I choose. Besides, relying on the wheel thimble means that you gotta deal with gear back lash. A DRO on the other hand provides an accurate measurement of the apron or cross-slide motion. My tail stock is already outfitted with such a digital readout accurate to a half thou also. I'm a big fan of precision, and this is gonna be a real treat. Tomorrow is mounting day on the lathe. If this set up works out to my satisfaction (no reason why it shouldn't as I've done my homework), my smaller lathe and milling head will be outfitted likewise.
