Sounds like a bit of an over-reaction for what could be a very easily solved problem. one of the 1st things I would suggest, pics, pics and maybe a video. There are folks on this site who could get a straight stitch off of a paperclip and an electric toothbrush!

I am looking at you @Uwe, @Constabulary, @wiz ...

Give it time to happen, @charlesfalzon.

Hey Charlie, don´t give up on the old dear yet, i think it will be something you might have not seen or overlooked?? I have an old singer 45k1 from 1895 with a wobbly needle bar and it has seen better days, it feels very worn and it was left to rust, but believe it or not it does not miss a stitch now the parts are on it.( it still has the wobbly needle bar on it!) If you take out your shuttle out, there should be a small screw for applying tension to your spring? if you have thin thread in the spool then you will not get any tension as these machines are made for sewing with thick thread. Maybe #207 bonded nylon would be a good place to start. There should be a little tension to the thread when you pull it from the shuttle, if not then tighten it more. If the screw is all the way in then it could be that your shuttle spring is worn, your shuttle case is worn or your thread is too thin?You can find in this post how to thread your machine properly and don´t forget to go around the pulley wheel 1 1/2 times after you come out of the top disks like it says in the manual. Like Rockoboy said, best idea is to send some pictures, that way someone could spot the problem from the pictures. Here are a couple of pictures of some of the 45k machines and the thread path.

There should be a bit of resistance from the thread coming out of the shuttle. This machine is the same as your 45k92 Charlie with the exception it was called the 45kSV99 before it was called the 45k92. This model came with a foot not a roller. Ohppss! forgot to put the thread behind the wire on the needle clamp :whistle:

Here is a 92 like the one you have charlie, and the foot it comes with.

And here is the old dear that wobbles...

And this is a common 45k21 cylinder version.

They all thread up the same way. If you could send some pictures then we could try to find a solution. Jimi.

What shaft are you referring to? the one underneath?? Here is a fix i done on a 45k92 i bought for selling, the back leg was missing and it broke right in the middle of the thread.

After that breakage is the bushing loose and turning?? or is it still  fixed in its position?? if it is still fixed and not moving then could you send a picture of your thread path.

If the shaft is not wobbling or the bushing not moving and everything is the same as before, then i would leave it. if not then...

I am no expert and only suggesting what worked for me.

What i would do would be to drill some small holes in the casting, put some small rods in and JB weld it. The epoxy sets hard as a brick. Normally i don´t think you would need to touch that bushing unless it was worn or something. The clamp would be to stop it from turning with the shaft i suppose. The other option is to pour the epoxy all over the bushing leaving the oil hole free and just fixing it so it can´t move. i personally would try the first option.

Also in the pictures on the other thread it looks like you are sewing on some thin felt?? try a thick piece of leather if you have some around. I don´t think These machines are meant for sewing thin material.

What size of needle and thread are you using??

Well at least it looks like a clean break. I would give it a try charlie, it worked well on mine and i had to pass a tap to make the thread on the epoxy side also. You would need to clean well the both parts where the break is, no oil and stuff. I would drill the holes slightly bigger than the rods to help line up the parts, then fill up the holes with epoxy, insert the rods and the join the parts together and let it set. If that does not work then look for a good welder. In the picture i put an example of 2 holes, if you can get 4 each side then better. If you do do it with epoxy then remember to tighten a very little amount.

Guys

just joined and completely new to sewing machines never mind leather sewing machines.  Your pictures and explanations are just what this newbie needed to find my way around the old 45K58 that I just bought.  Constabulary is supplying me with the missing  tension assembly and college has supplied two new springs.  Hope you don’t mind me butting in to this discussion but just wanted to say thanks

 

Frank
