The Beast

Introducing the Beast. No beauty here! He is a 1923 Singer 96-10 industrial sewing machine. According to the manual I found online this machine was used for "cloaks, clothing and other work in cloth. Drop Feed. Speed 3200 R.P.M." Eventually he will get a new paint job as he has had a very hard but useful life.
I took him to the OSMG for a check up as I could not get him to stitch. Well, the OSMG said that the wrong bobbin was in the machine. But even with the correct bobbin the machine would not stitch. After a whole lot of trouble shooting the OSMG discovered the problem. The end of the rotating hook shaft (I think that is the name of the part) is bent, see last picture. It is very perplexing as to how that end could get bent, perhaps it was dropped when being re-mounted in it's table?? I need some ideas as to where to find another shaft. I believe the part number is 52308. Also, I loosened up the set screws that secure the shaft in the bushings. But it will not come out. I figured it would just slide out when the set screws were loosened. NOT. Any ideas on how to remove the shaft??? If I can remove the shaft I will try to have it straightened. |
Could a good metal mechanic repair it?

You might take it to an auto body shop, they might be able to bend the shaft back in place without removing the shaft. Or at least they may know how to remove it.

I wouldn't know a rotating hook shaft if it fell on my foot ... so which part is it??
Is it the long metal rod that runs from the far right of the machine, through the black part - and there is perhaps a 1/2" - 1" piece sticking out the other end of the black part (I know .. all these technical terms I'm using!). If so, that should be easy to find or make. I would remove it entirely and bring it to a machine shop - but make sure they know that it should be straight - not bent (or they may duplicate the problem). Without knowing what is on the other end, or the exact diameter - it looks like a piece that my husband machines for the machines that we make. We make sowing machines - not sEwing machines - sOwing machines :) |

Can we see how the other end attaches?? With all of us putting our heads together, I bet we can figure it out...

Found my answer. Duh! Had it all along with a copy of the manual. It was in the packet that came back from the OSMG. It is "Instructions for Adjusters and Machinists. I bet he has the original in his stuff. The instructions show how to replace the shaft with a new one. Problem is I don't have a replacement and OSMG says they are not available. More thinking to do.

DH says the great fellow that cast iron welded my treadle could put the part on a metal lathe and straighten it with pressure. He's an amazing gunsmith and a good friend of my DH. Did you get it out?
I'm thankful you posted the pdf. Makes a difference when trying to understand what we were doing wrong. Ain't information grand!?! |
He looks like his life has about run out. I hope you are able to fix it and use it.

It could probably be machined if worse comes to worse, after all it's only a rod that will need to be threaded, etc, but it won't be cheap!!
