Adapter, 5" Lathe Chuck, Rotary Table 

5" Lathe chuck adapter. This adapter has a 95 mm diameter registration boss, and has 6 chuck mounting holes. The adapter is 6" in diameter.

This adapter lets you mount a 5" 3- or 4-jaw lathe chuck on LittleMachineShop.com PN 2326 6" rotary table. It can be used on other 6" rotary tables with some modifications. There is an alignment boss that projects into the tapered hole for quick alignment. It is clamped to the rotary table with T-slot nuts that are not included.

The locating boss on this adapter fits a 30 mm hole, so if the hole in your rotary table is 30 mm this adapter will work without modification. If the hole is smaller, you will need to turn down or remove the locating boss.
