Does this quote seem reasonable?

It is easy to get a depth stop that you require.
Doing something like I have shown in the sketch will get you within a couple of thou tolerance for each one.
You don't have to use the bit of wood, as long as you touch on the tailstock chuck, then back off a couple of thou before tightening your lathe chuck. Otherwise if you use the thin bit of wood, pull it out before starting the cut. That will stop it jamming up at the very end the cut off.
