Out of curiosity sake, I looked up the parts schematic for the machine...machining would/might be a good option as I didn't look close enough at the pictures to see that the shaft separates from the end. Find a piece of tool steel and have it turned on a lathe, then machined for the profile on the end that is bent. At the quoted price, I would have it done as it seems cheap. Depending on where you are located in the states, machine shop prices can be astronomical for tooling up for just one part. That is the whole reason I put myself through school(s) to learn...because I didn't want to pay that high price. I would gladly make a few mistakes in my garage, then to pay some absorbent price! Keep us updated!

Cheers Chayse - Yes the shaft separates from the shuttle driver so its not too tricky to machine. I'm in the UK at the moment and there seem to be quite a few small time machinists offering relatively low prices for their services. I found quite a few on eBay offering CNC/Milling/turning services for a fixed hourly rate. Very convenient! We are soon to be moving the workshop and all our machinery back to Brisbane, Australia so i'm trying to get everything fixed up before we set off. Lots to do. Cheers.

Why not try and straighten it? You can hardly make it any worse. Any idea of how force was applied to the shaft to bend it in the first place?

Hi there - I'm not sure how it got into that state to begin with but the previous owner did hint that it "may have suffered a bit of a knock during its last move". I have tried straightening it but even with a bit of heat applied I couldnt make it budge. I could try more heat and pressure I suppose, as you say it cant get much worse..

I found a nice, straight original 91171 SIMANCO shaft with shuttle driver for Singer 45K in my parts drawers. $70 plus shipping.

Wrinkle alert!

I just noticed that the shuttle driver on my shaft is mirrored from yours. I've been wondering why my shuttle driver is marked "Left". I'm guessing it's for special "left handed" versions of Singer 45K machines where the arm points to the right.  That means you can't use my shaft+driver assembly as it is in your machine. You'd have to move your shuttle drivers to my shaft.

I may have a "right" shaft hiding in my drawers, too. I'll let you know if I come across one.

I have few of them,  I will check the part numbers when I get home tonight.

The shaft itself is the same, it's the hook driver that's different. We'll "just" swap hook drivers and all should be well.

I "Just" removed the shuttle driver from the broken shaft in preparation for the new part.. It took some work to get it free without damaging the eccentric portion just below the driver proper but its done now. All good fun.
