Re: Lathe Spindle sizes
I agree with Leo and the OP on this one - belatedly. This thread has gone off subject and seems now to be more about whether a given diameter of shaft will put up with certain loads. That's not what the OP raised. The issue is whether, as purchasers of lathes, we accept that a manufacturer can claim that the spindle size is 1.25" when, in fact, only the threaded part is that diameter. Those who are arguing that this is acceptable seem to be basing that on the fact that the 1" shaft will be fine for the purpose to which the lathe will be put. That was not the original point of the thread. I am not an engineer, but I'm assuming all those on here who have stated categorically that the 1" shaft will not flex are engineers. Good on them. However, to repeat, that was not the question put to us. If the engineers believe that it is acceptable to mislead or lie about the specs of a machine, I can only hope that I never need to use a machine that they designed.
