Product Information
Description
This is a semi-machined adapter plate. The side that attaches to the lathe flange is fully machined. The side on which the lathe chuck mounts is not finished.
Mount the backplate adapter on your lathe and complete machining of the chuck-mounting side. This ensures two things; that it will fit your chuck, and that it is concentric on your lathe.
Chris's Tips
Too many adapters?
See our chart that correlates lathe spindle threads to lathe chuck adapters
Here is a 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.
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.
