@Tastechthank you. Im having trouble finding a servo motor that looks like it will work. Could you point me in the right direction?

@Tastech back again. The 31k48 sat on marketplace for another couple months so I talked the price down a bit and went and tried it. It stitched 5 mm thick like it was nothing and even up to about 7-8 mm. So I went ahead and bought it. Now my question is what needles do you use and up to what size can I run? I received some shmetz 18s with it which I understand could run M40(69) or maybe M36 thread, however if at all possible I would like to run M20(138) with a 22 needle, just wondering whether you've tried anything like that. What size thread can I run in the bobbin? If I could run M36/Tkt92 I would be happy. Also it is extremely fast- what servo motor do you run and could you maybe give me a link? thinking that may be quite helpful in the near future. Thank you. Hugh

@Tastech not my machine as of yet just one available on fb marketplace. I’d be running veg tan rather than chrome tan not sure if that makes a difference. I assume it has the old clutch motor rather than a servo motor. How do you find wheel feed vs walking feed for this kind of work? I’m on the fence about getting a machine but if it will work for what I want then maybe I can get him to drop the price and pick it up to start with.

@Tastech I would be running a layer of 3.5 mm and a layer of 1.5 mm so 5mm total. Do you think it could do that? Thanks for the reply

I have an opportunity at a few different old sewing machines in my area. Wondering if anyone had any opinions or feedback on them. Mainly doing tooled belts so a layer of 8/9 oz and a layer of 3/4 oz. Would maybe like to do some thicker stuff such as breast collars and saddle parts in the future but on a tight budget for now.

I know this is an old thread- but I have an opportunity to purchase a singer 31k48. What does everyone here use them for? Is it a good enough machine to do lined leather belts so a layer of 8/9 oz and a layer of 3/4 oz? What’s the difference between the 31k48 and the 31-15? Thanks Hugh
