I don't know if they still have them , LMS used to have these
DRO's that mounted behind the handles on the compound &
Crossslide that were made for these small lathes . As far as the
carriage ya probably would need a linear scale , ya can go from a
Digital caliper all the way up to a Magnetic scale for that one .
Have ya looked at TouchDro ?

I've been looking at DROs again.? Seems I go through this
exercise every six months or so.
Wanted to bounce off the conclusion I always seem to come to and
see if you guys have a different opinion.
1) Tailstock.? This seems like one of the easiest (cheap caliper
modification) and cheapest.? I'm not sure the accuracy of
calipers is necessary, but it's so easy to do that maybe why
not.? The graduations on the tailstock are getting hard to read
and a magnetic dial indicator is easily bumped.
2) Carriage This seems the easiest to implement, and also the
most useless.? Even if I put a handle on my leadscrew, the feed
is awfully coarse.? Typically I use the carriage to get close,
lock it down, and then feed with the compound.? The only time it
might be useful is turning a diameter on a long enough piece
that the compound doesn't have the range on it's own - even
then, if I had to turn to a shoulder,? I'd still likely set a
carriage stop and advance the last few bits with the compound.?
Maybe I'm doing it wrong
3) Cross-slide.? I think this one has some merit.? Not too
difficult to implement and with the slop in the screw, having
absolute measurement would be useful.? Leaning heavily towards
this one.
4) Compound.? This one would be most useful, but it's also the
hardest to do especially without getting in the way, and it's
complicated if you angle the compound.? I'd like to do this one,
but I'm not sure if it's doable enough to make it worth it.

What do you guys think?
