I didn’t think about the fact that my father has been retired for 16 yrs, the book I have is dated 1999. I guess I’m a little behind the time.
Cheers!
 
Mikey, I finally got the models. They are like nothing I've seen. Now on to keystock so I don't ruin my USA lathe bits.
I also have a dozen or so that a friend gave to me that are ground but need re-grinding and honing. I'll post a pic soon.
It;s great to see the real thing up close. I'll post images of what I've ground after some practice. These models are invaluable.

Glad to hear that you got the models.

Take your time, post pics when you can. If I can, then you can (grind them, I mean)! When you buy your lathe they will come in handy.

Emilio, glad to hear they got to you. They are pretty amazing.
I was just using the tool I made to turn some 6061 and was able to take .001 off a 16mm long 3mm diameter pin, I could never do that before.

Many thanks to Jeff and Mikey.
 
Which DTI model or models, are accurate to use in a lathe when taking small cuts? To gage travel?

You can use whatever you have that will directly read cross slide travel. Doesn't mean the tool will make the cut but you can try it. A 0.001" deep cut is no problem, and usually half that is easy, too. The tool can usually cut what you dial in but on a thin work piece that deflects you may have some variation with really fine cuts.
 
I taught machine shop classes for several years at a 2-year college. I made up some sample cutting tools out of wood blocks. I would make them out of 1" square wood strips in the wood shop. I could write on them with marking pens for the cutting edges, relieve angles ect. The students would then practice on wood blanks until they had the angles and clearance down. I always left several examples of wood cutting tools around the shop for reference. Of all things I taught, hand grinding a good HSS tool bit was the hardest concept for the students to grasp.
