I have seen a couple of? Graduated 3D printed dials over on
Thingverse or some of the other hosting sites & I believe ya
can change the program o enlarge or shrink the hole to fit a lot
of applications . Could ya? please share a couple of pic's of the
Rose lathe ?

I have the cross slide from a mini lathe mounted on my small
woodturning Rose Engine lathe. As this cross-slide is metric
and the current graduations on the compound hand-wheel are
only 0-39 rather than 0-10 with intermediate graduations I
decided to look for an alternative that allowed the resetting
of the graduated dial. I found this one on
At the time I bought it the cost was ?17 but I see that it
has since increased slightly in price. As the 8mm hole in the
centre of the new hand-wheel had a keyway slot in it and it
wasn't deep enough to used the mounting threads on the lead
screw I mounted it on my metal lathe and bored and reamed the
centre hole to 14mm. I then turned a T shaped steel spacer
with a M10 thread in the centre that I press fitted into the
14mm hole and used Loctite to keep it in place. I then used a
1mm thick brass washer to separate? the hand-wheel from the
mounting and used the conventional second nut to reduce the
backlash in the compound and to lock the hand-wheel in place.
The graduated dial is slightly larger than fixed base but for
my use I don't think that this will be an issue.
The cross-slide has a similar problem with the graduations
and I happened to have a larger ring with suitable graduations
on it but the centre bore was too large to fit. As a result I
left the existing small graduated ring in place and 3D printed
a spacer that grips the small ring tightly and has just enough
friction to retain the outer ring but to allow it to be moved
if necessary.
