quill/way tube separation and way tube spacing.
The real problem is where the speed reducer clamps onto the quill housing. The clamping surface on the 10E/R is much too short, if memory serves. I didn't see any straightforward way to adapt it.
If I ever get serious about extending the speed range of a 10E/R, I'll probably mount 1-2 hp, 3-phase motor on the machine and power it from a VFD. I recently got a good deal on a 2 hp, three-phase dust collector. So I bought a 3hp TECO/Westinghouse VFD for it. That cost $200 retail, and so is pretty comparable to a used speed reducer. And now I have a variable speed/noise dust collector.
Around here, three-phase motors can be bought quite cheaply on CL. And since they don't have a starting circuit, they are considerably more reliable. The bearings and windings are the only parts that can go bad.
I did not dig out my speed reducer but I agree with you about the way tube bracket. The 10ER spindle is 3/8" closer to the way tubes than the MK V so it should be easy to fabricate a replacement bracket. As for the quill clamping I think that should work also. The clamping distance of the 10ER is 3/8" and the MK V is 9/16". That is only a 3/16" difference. Given there is vertical and horizontal support provided by the way tube clamp and horizontal support provided by the speed reducer being attached to the quill spindle I think it will work. I will dig out my speed reducer and do some checking in the next few days.
