If you had a largish lathe (18"x72") but didnt know the MT # of the
tailstock, how would you go about figuring out what it is? I need to get a
new live center, want to get the right MT.

Thanks for any info.

Table on page 906 of Machinery Handbook has the specs. If you don't have
this, give us the diameter at the small end of the taper, diameter at large
end, and distance between the two diameters.

Hey Greg,

Scott Logan has some good stuff at

and in particular

or closer at

The following is an excerpt from that last site

I would measure just the diameter of the visible opening of the
tailstock quill, and pick the closest one form the column "Large End".

18" lathe is at least a MT-4, and probably an MT-5

Take care.

Its a #4 of course.
