I have figured out that the spindle on my lathe Standard Modern is L-1, but none of the charts I have found dimension the inside taper.
I have a 5MT live center laying around that is way to small.
The open end of the spindle measures 2.34". Can I safely assume that is a 6MT that is a little small so that it projects through the dog plate?
6MT tooling is starting to get expensive, so I don't want to buy the wrong center if there is some other odd taper.
