I have a customer with an old SCM shaper that goofed and sent the spindle nut with another machine when it was sold. He is not a machine guy and I figured it would be an easy thing to figure out what he needed. He told me he called SCM and they couldn't tell him what he had and weren't any help. I have not called them myself, so just going off what he said.
I took my sae thread gauge over, should have dug out my metric as well, but didn't find it before I went to deliver parts. Anyway, the spindle is using 1.25" cutter heads and I measured with calipers it is 1.250-1.253" OD on the threads. The threads look to me to be normal 60 deg threads. None of the sae threads fit perfectly. A 13 tpi was very very close, but wasn't quite there. When I got back to the shop I found my metric gauge and I think the spindle is a 2.0 thread pitch. So, best guess is that it is a M32x2.0
My problem now is I am not 100% sure that is it and I am not finding any sources for any actual nuts in that size. So far I have only found a chart that shows the thread dimensions, none for sale.
So, could it be a M32x2.0, could it be a 1.25" x 2.0mm? Is the difference between the 1.250" OD and the 32mm (1.260") enough to think it is not a 32mm thread? I'd feel a little more confident about it if there was any nuts in that size.
Lastly, anyone know where to find a M32x2.0 nut?
Thanks,
Jason
