Chris' Tips
Too many adapters? See our chart that correlates lathe spindle threads to lathe chuck adapters and our chart that provides dimensions of threaded lathe chuck adapters.
These adapters must be machined on your lathe to fit the chuck so that it is concentric on the lathe. In most cases you have to drill the chuck mounting holes also.
We provide complete instructions for mounting the adapter. Our transfer screw sets are the perfect tool for marking the chuck mounting holes on a lathe chuck adapter.
WOODWORKERS: Our threaded adapters are not suitable for use on wood turning lathes. Please do not purchase them for this application. These adapters require machining on the lathe on which they will be used, and this is impossible on a wood lathe.
