Bent shaft

<< < (2/2)

John Rudd:
I was thinking, chamfer at 45 degrees, drill both ends, insert suitable joining piece and weld up..Then machine weld to finish dia...
Yup, Andrew tis my armature shaft... :lol:

awemawson:
Concentricity is your problem welding. It might be absolutely fine when you set it up, but it won't be when it cools.

I think I had sufficient length spare to make a male & female thread meeting conically. Or I might have drilled and tapped both ends female and run a stud between them - don't remember. I do remember debating long and hard over the cross pin - stops unscrewing but makes a weak point. Anyway I did and it hasn't broken (famous last words!)

mattinker:
This is only 5/16 shaft, why not try straightening it?

John Rudd:
Think I'm going to have to strip the armature and remove the stack, down to the bare shaft and see how it is... :scratch:

mattinker:
John,

Do you have a way to set it up on V or other blocks to find out exactly where it's bent, you might find it's bent next to a bearing seat. It might well be possible to straighten it without stripping it!

Cheers, Matthew
