The headstock taper on my 10 inch Logan is a #2 Morse. I thought
that all American Made lathes used Morse tapers.

Brad,

I think you'll find that the taper in your headstock is actually a #3
Morse. The large end is 0.938" dia.  You might have an adapter stuck in
there.

Actually, many American machines do not use Morse tapers.  The larger
Logan's used a proprietary taper, and many South Bend's used a Jarno
Taper.  Many of these tapers are similar to a Morse, but slightly
different, so you need to be careful on what you get to go into the
spindle.
