I need a new PTO shaft and associated part machined to replace a broken one for a tractor; new ones are no longer made for this make and model. I took it to a local shop (central MD) and they said they couldn't do it because it's hardened. Looking around online (I'm not a machinist/metallurgist) I see that steel can be hardened after machining, and that this piece isn't hardened all the way through but just on the surface, given its use. Can someone point me in the right direction, either to a shop in MD/VA/PA area, and what to say over the phone to ask if they can handle this job?
Luckily I have a friend who is a mechanical engineering PhD who runs a university fabrication lab and could possibly design the piece in CAD for me, which I'm sure would cut costs minus all the beer I would buy him.
Photos here, it's under 10" long and 2" in diameter. The lip which keeps the circlip on sheared off (second photo).
