Fresh from my last triumph :-) My neighbour brought round part of drive train for the sawbench on his Nuffield today. The PTO coupling is (was) keyed onto the saw input-shaft and then locked with a bolt onto the key. By the looks of it the bolt dropped out year ago and the coupling has been fretting until today when it sheared the key and tore the keyway out of the shaft. I propose to clean up the shaft, build it up with weld, turn it true, and then machine a fresh keyway in the more or less undamaged part of the shaft. Comments on this proposal or offers of the parts most welcome. Trite banality unwelcome :-) ttfn

That's it ruin my banal Diatribe, reading this dictionary is great fun, I used to use it as a door stop but I've just realised how good a read it is. The plot is not a lot of cop though:-))
Cant fault your method except the welds may be a little tough to machine. How about making a collar with the keyway and then turn the shaft down to size and weld that on.

Normal practice, although I generally turn the shaft down before welding if the buildup is likely to be minimal..
