Heavy 10 and 10L compatibility

[PHDesigns]

What parts of these two machines are compatible? Specifically looking at the reverse tumbler.

The 10L is the designation for the Heavy 10. They are the same machine.

Heavy 10 refers to same lathe as 10L. however...

10L is the Heavy Ten lathe w/ Large spindle bore (5C capable). Could be 2-1/4 X 8 TPI threaded, D1-4 camlock, or L-type spindle.

10R is the Heavy Ten lathe w/ Regular spindle bore (not 5C capable), that is 1-7/8 X 8 TPI spindle thread.

All parts are interchangeable, depending.... and that is open ended, depends on unit code, older or recent build. However spindle bearings between 10R & 10L and associated parts w/ those various spindles may not be interchangeable. And various parts between single & double tumbler, are not either.

The reverse tumbler is the same across the board.

Thanks for the info. Mine is the large bore with the 2 1/4-8 spindle nose.

"Spindle Assemblies", are interchangeable between 10L & 10R.

I have a 10R w/ 1-7/8 thrd nose. I did transplant a 10L 2.25 thrd nose spindle assy to make it a 10L, so I could use 5C's.

If you're already replacing your reversing tumbler, have a look at PM member Zahnrad Kopf, aka American Machine and Gear Co. on the outside. He makes a really nice set of "silent" reversing gears for the Heavy 10 that run on needle roller bearings. Good stuff.

Yeah, I looked at those and would be nice, but pricey at the moment and my tumbler is not worthy of such Just bought a tumbler assembly off ebay so hopefully will be able to go from there! Thanks.

Jeez!, what a coincidence. I was just wondering about that. Morsetaper2 in a subsequent post further clarified things.
