Rotary Table / Chuck Adaptor.

(1/4) > >>

Stilldrillin:
I want to fit my 80mm chuck onto my 100mm r/table.

The plan is to locate the chuck onto a 100mm x 3/8" adaptor disc, as on the lathe backplate, held by 3off c/sk 6mm screws.
The disc will be held onto r/table by 4off 6mm capheads & t nuts.




Friction drive, topping a piece of 4" square..... Knocking me little lathe about, making it all slack & sloppy........  ::)




All tightened up again, starting facing operations......  :thumbup:
This is as far as I`ve got today.




The problem, is that the disc is too large dia for my chuck to grip......

Do I drill & ream (no boring bar) & mount on a mandrel, before proceeding further?

Do I rough out the chuck locating spigot now, as set?

The r/table has 9/16" location recess between segments.
Or I could drill into the centre for a shallow, smaller dia location hole, for setting up purposes.




Any ideas or suggestions greatly appreciated......  :wave:

Hi Dave

Have you got a face plate ?. If yes drill the holes in RT adaptor plate where they will go to clamp the RT chuck.
Use these to clamp to the face plate, face it up and turn the chuck spigot, turn it round on the face plate clean the back face up, Job done.

John mounts his in the MT2 taper in the RT, wouls that be poss with yours?

Double sided tape might help when holding against the lathe jaws, still need the tailstock support though  :thumbup:

Stew,

No faceplate.........  :scratch:


Darren,

No morse taper hole in r/table.  :scratch:

Using insulation tape on jaws for friction drive,  that part of the process is working ok......  :thumbup:

The problem is, the o/d is too large, how to hold it for the next ops.......  :bang:

Darren:
David, not insulation tape, double sided  :thumbup:

Umm, can you do the holes on the mill?
