Re: Will Myford Gears fit the 10F
That's an interesting question. There are two issues, DP of the gears and
the bore and keyways of the gears.
The simple answer is you can't mix the 20 DP Myfords with the 16 DP Atlas
gears where the drive is through the gear teeth. The part of the drive which
creates the biggest problem is the spindle gear and the gears on the tumbler
reverse mechanism. If you could replace all of these with 20 DP gears the rest
of the drive would pretty much be a straight swap. Alternatively, if you were
to keep the 32 tooth gear on the tumbler reverse and all the gears above it
but alter the 32 / 16 stud so that the 16 could be replaced by any 20 DP
gear, then all gears from the stud down could be Myfords.
Finally, you can mix different DPs in a gear train as long as the drive
doesn't require meshing the teeth of different DPs. So you could have the
original Atlas 32 on the tumbler drive an Atlas 48 on the compound bushing, then put
a Myford 60 on the compound bushing driving a Myford 80 on the leadscrew.
With an 8 TPI leadscrew this would cut a 16 TPI thread. (This isn't a
particularly useful setup, there are better ways to do it, it merely illustrates the
method by which incompatible gears can still be assembled into useful gear

Picked my 10F up yesterday and although I've got a load of tooling and
parts with it there are some gears missing. Being in the UK, Atlas
parts are a bit thin on the ground but there is plenty of Myford
stuff. Does anyone know if Myford gears will fit/work on the 10F lathe ?

- Thanks Jean-Claude
Should have guessed that that would have been too easy.
Have to keep an eye out for the odd one that may come up at car boot
Is there an easy way to identify if a gear would be suitable ?
