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!

You can't do that.
MT1 and MT2 are two different sizes of tooling. There are sleeves that can be interposed to use the two together, but usually you'd be trying to use a smaller MT male- shanked device with a larger MT female (inside) bore (headstock or tailstock). Since your lathe is MT1 on both ends (both bores), it would be extremely unusual to mount MT2 tooling on your lathe. It would be by what are termed extension sleeves--MT1 (male) external taper to MT2 internal (female) taper. These to exist, but their use on your lathe would make no sense--small capacity lathe doing large capacity lathe work. Frank Morrison
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. Billh
Billh.... Took your advice and checked out the dimensions and it appears that the MT1 is .475 at the large end while the MT2 is .700 at the large end.... so this is what you were talking about the MT2 won't fit "all the way into" the MT1 spindle.
Thanks to All for help... I didn't know that they were that visually different in size.
Morse Taper Sizes
Size Diameter Diameter Length (small end) (big end) #0 0.25" 0.37" 2-11/32" #1 0.37 0.47 2-9/16 #2 0.57 0.70 3-1/8 #3 0.78 0.94 3-7/8
MT sizes go up to #7, but this chart shows the common sizes. Small MT tapers can be adapted to larger spindles using Morse-taper sleeves. Having a Morse taper spindle on your lathe is a big advantage to fitting accessories. There are other taper standards other than Morse.
