Looking at the tech data sheet for 620 it looks like the goods for this application, can be used in shrink fit applications- heat the collar, apply to the pin and use high press rates (which I assume means assemble quickly).
The torque load on this shaft is only what I can apply with my wrist, is it not? I don't imagine the axial load is particularly high either?
I won't cut the shaft until after I have made the nut (hopefully second time lucky) which I hope to achieve early next week.
I have to confess to a stupid rookie mistake- I discovered the reason for my failed internal acme threading effort- I ground the tool with the clearance angles the wrong way, i.e. same profile as the tool I ground for the shaft. It was rubbing the back off the thread the whole time. Did I mention I haven't been doing this long?
