The MT2 wouldn't fit because its diameter is larger. If you put a MT1 into
a MT2 hole it would be very sloppy and fall out. Without knowing the easist
way to determine what you have would be by measuring the diameter at one end
and they are different enough that a ruler would do. Do a Google search for
"Morse Taper" and you'll likely find a table of the dimensions.

I have a lathe that takes MT-1 spur center and MT-1 live center. Seeing
that I don't know much about lathes, what would happen if I put a MT-2
spur
drive into the MT-1 spindle? Would it fit? Would it fall out? Is there
a
visual difference between the MT1 and the MT2? Can they be mistakenly
interchanged? I know they have different taper dimensions but how do you
know what you have without a mic or label?

Thanks.... Just trying to Learn!
