I have a 10 Rockwell-Delta 10" metal lathe in my garage.
It has a non-standard taper (I think) in the spindle. Not morse, in any case.
Anybody able to tell me what the taper should be? I had thought that I had read it to be a B&S 9 taper, but tthe measurments dont jive. Larger than an MT3, smaller than an MT4, and looks too shallow a taper to be B&S.
I have measured as best I could, the taper on the very rough looking adapter that came with it, and it looks to be 2.5 degrees included angle, or around .48" per foot, based on the inch that I was able to measure. This does not seem to match any of the tapers in Machinery's Handbook.
Anyone got a reference that gives the taper? It's not given in the factory book that came with the lathe.
My intent is to grind down a MT4 to MT2 taper sleeve so that the outside matches the machine spindle, using the T&C grinder at work. This should allow the future owner to utilise MT2 centers and tooling in the spindle.
I plan on selling it when it's ready to go.
