I recently bought a LeBlond Regal 13 x 30 lathe. It's a manual shift machine. It does not have a DRO. I've been just basically doing simple stuff on it like turning, facing & parting on aluminum. The cross slide is diameter reduction. My newbie question is: the various charts usually state how many thousands to cut depending on a bunch of factors but they are radius cut values (I think). So, on my cross slide dial, I should double the value?
