Anybody familar with a Jacobs 2A taper? Based on the fat end
measurement, it might be a "2 Short", but I can't find any references
to 2A, and that's what is stamped on the chuck. Haven't figured out
how to measure the narrow end or the depth accurately yet.
It's a nice chuck, came free with the lathe, but the MT2-JT2A arbour
seems to be on permanent back order (or the vendor is pulling my leg).
Anybody know if I could use a MT2-JT2 arbour instead of "2 Short" or
