When buying a Threaded Chuck Adapter

To help you get the right threaded backplate lathe chuck adapter, we have a chart that correlates lathe spindle threads to lathe chuck adapters and a chart that provides dimensions of threaded lathe chuck adapters.

The first rule of buying a threaded adapter is to measure the threads on your spindle. There are simply too may variants of every kind of lathe to trust any chart. Here is a Paper Thread Gage to help measure.
