Ok guys, so I've cut a new twin start thread and machined off the original single start worm. I can confirm that the stitch length has doubled and the machine seems to be stitching really well! I'm only turning it over by hand at the moment. Under the top cover plate there is adjustment for the swing of the needle front to back. There's easily enough adjustment so that the needle doesn't have any strain or bending. Now I will go ahead and restore this machine, it is properly filthy! I needed to know that it would make a decent stitch length before I bothered to restore it. Have a good weekend guys.

Thanks Bob, I understand what you're saying. I suppose the leather thickness and hardness will play a part too? I'm having a play with what is possible with the machine from an engineering point of view really. I've got 7 industrial sewing machines now, so I can tinker on this one a bit. I've managed to make a new twin start worm gear for the feed mechanism before the gearbox, so that still allows me to keep 3 stitch lengths, as the original machine. The stitch lengths will have doubled though, now 2mm, 3mm and 4.4mm, which would make the machine much more useful to me. I would use it with 1.5mm chrome tan leather. Once I have reassembled the machine I'll let you know if it works at 4.4mm or 3mm stitch lengths. If it only works at 2mm then I guess I've not changed it from the previous maximum length, so I won't have gained or lost anything. Fingers crossed it might work.

Thank you for the info Constabulary, that is very kind of you. Looks like I'll have to make a custom gearbox. I'll let you know how it goes...

Sorry, I picked the same page from the manual, meant to pick the 2nd page. Here it is.

Here's some more photos. I've removed the gearbox cover plate and you can see the 3 pairs of gears. Any help would be great thank you.

Hi guys, I've just bought an old singer 136w100 postbed roller wheel machine. The stitch length adjustment goes from super fine to fine, there are only 3 settings. I've got the manual and it says you can change the gearing to only have 2 settings but the manual never mentions stitch lengths. I think the maximum stitch is 2mm at the moment. The finest setting is probably half that! I'd like to get 4 or 5mm stitches if possible? Can it be done by swapping the gears about? Or will I have to make some custom gearing solution? Many thanks John

Wow, I love it. A fantastic machine on a wonderful old bench. I have the Hightex clone copy of the 335, it was the first machine I bought. I made the leather interior for my Fiat 600 Multipla with it and the convertible roof for my Fiat 500d, plus a few other projects. I made a flat bed aluminium table for it because I didn't want to buy two expensive new machines. It's much cheaper to restore an old quality machine than to buy a new clone. Although a brand new machine is easier to learn on I think.

Thank you! I can't believe how smooth they sew. Looks brilliant!

Yes, you're right about the bench, the old ones just look better though Cheers!

Love that long arm machine! Quite a rare beast I think, I haven't seen any of those come up for sale. Love that you saved it and that you use it. Great size comparison against the small sized home machine.

Thank you!

Thanks, the table will be saved but I wish I had an old cast iron industrial Singer table for it. The red is actually so much darker in real life, it's RAL 3003 I think. The main thing is that it works very well, in fact it sews through thicker leather better than my brand new Hightex machine. Amazing considering the age and abuse this poor machine has had.

Thanks! I couldn't let this one go into the skip. It was just about to if I hadn't bought it..... The red is much darker in real life, the camera makes it look really bright. The great thing is all the cool stuff you can make with one of these lovely walking foot machines.

Thanks, I wanted them to be the same as the industrial ones but could only find the more ornate Singer home ones online.

Ok, so not original colours I know......... I thought that as the machine was pretty much a lost cause, it wouldn't hurt to spray it a different colour. After all the machine is for me and not to sell on. The machine has been slowed down to 1 stitch per second using homemade speed reducer pulleys and a servo motor. I added a synchroniser. The singer logo was made from the photographs of what was left on the machine, it was supposed to be gold but turned almost black when applied to the red paint, so I won't worry about that. As for sewing, I have been through 4mm thick veg tan using 20tkt thread without a problem. Next up is to replace the edge of the sewing table (wish I had an original Singer industrial table but never mind!) and to start using it in the evenings. Good luck with all your sewing projects, I hope my little rebuild pics might inspire someone else to save a machine from the skip.
