Question about boring on a nardini

kielbasavw · May 11, 2018

I was using my buddies lathe for the first time to bore out some spur gears. I believe it's a Nardini lathe.
What I noticed was when taking say... .010 on the cross slide, it cut .010 total ID. It was a 1:1 ratio.

Is this a common characteristic on some lathes?

not common but yes

I believe that is common in Europe. No idea about Asia lathes made for local use.

Harrison lathes used to offer a choice of apron handwheels on left or right. One side being more common in Europe the other way more USA.

It's called a direct reading dial, what you dial is what you get. The actual movement is 1/2 what the dial reads. My SB Heavy 10 is like that.

3 of my 4 lathe are depth of cut ie .010 = .020 on dia. My other machine is like your ie .010 on the dial =.010 on the dia. Not as common but not real rare either.

I believe the right or left hand apron wheel has more to do with whether it has a gap bed or not? With the gap the rack gear stops at the gap so the hand wheel is on the right.

Exactly. I've seen lots of lathes with both configurations. There is no standard--you just have to know how YOUR lathe reads...
