Adapter, 4" Lathe Chuck on 4" Rotary Table CLOSEOUT 3782  (Discontinued) 

This adapter attaches to the rotary table with some special tapered T-slot nuts that are tightened by the 4 cap screws around the outside.

You mount the adapter to the chuck with cap screws using the holes around the periphery. It will mount either 3-Jaw or 4-Jaw 4” (100 mm) chucks.

Remove the 4 cap screws around the outside. Slide the special T-slot nuts into the T-slots on the rotary table. Set the chuck and adapter over the T-slot nuts and reinsert the cap screws. The adapter is registered by the boss that extends from the bottom of the adapter. Tighten the 4 cap screws evenly.

This adapter will only mount a 4” (100 mm) lathe chuck on a model 1810 or 2420 rotary table. It will not fit any other rotary table.
