Hey Guys, I was wondering if any of you know what the thread on 9" jr spindle is. I'm at work right now so Im unable to measure it. I have a three jaw chuck that doesn't have an adaptor plate and I'd like to order one.

1.5x8, same as the later 9" workshop machines. However, the crests on the spindle threads are very sharp- you might have to open up the threads on a new backplate, just a touch.
