Sham

I have one on a treadle, works good for thin leather, shoe uppers, etc. the machine is not made for real heavy stuff anyway. Easier to control on a treadle

If you wanted to use a Chicago screw, you could grind it down, I do it a lot , not that hard if you have a sander, grinder, dremel

@Wizcrafts wow, my mind is blown, I just had a few missed stitches when I changed direction, went through an existing hole and when the bobbin was running out. I also was sewing thin leather, with a little gap between dog and foot. im actually using the foot more than the wheel. But this is an eye opener!

@DonInReno wow! I just assumed that should be done, damn! .. that’s crazy, I’ve been doing it for years. And was thinking the design of the machine was really not conducive to that! ok, well enough of that then, pressure adjustment only now, what do you think is a good height? Just so the teeth aren’t touching?

@Constabulary on a non walking foot, like 45k25, 31-20…you would sew a thin piece of shoe leather and two pieces of veg tan belt leather with the same foot clearance? I guess you couldn’t do that on a 31-20, but the concept is same

@Wizcrafts any machine really, but 45k25 specifically, I usually adjust my 31-15 do a piece of paper can d add life through when the teeth are at their highest. But I only see thin leather on that

What is the proper way to adjust foot height to material thickness? Do you make it just a little less that the material, or leave it just above the feed dog teeth? Or something else?

@DonInReno thanks! Yeah, I really like old black iron stuff, prefer to keep it going. Fingers crossed. I looked on eBay in England, lots of em for $200-300!

Thank you @Constabulary and @Wizcrafts ..,amazingly, I just raised the feed dog up and sewed with it, snd it was working well! I’m not convinced yet, but I am hopefull. I wonder if the cb machine or other clone would be close enough to swap out a feed crank? I would doubt it? I have some techsew tension parts and needle plate that I haven’t tried yet, but look right

Thanks @Constabulary, I think it’s #91163 but I’m not sure. They’re going to talk to me soon from the shop. Sewing guitar straps, belts, belt loop key things, shoes. I like the 207 thread

Man, I just spend a bunch of money and time getting my machine serviced, and it was great briefly, but now it only makes tiny stitches and a little intermittent. I’m airing to hear back from the mechanic, but they said something’s worn out and not holding. I think it’s the feed crank 91163, but I’m not sure. I love this machine and I’d be happy to get it going, but wondering if I should cut my losses and buy something else ? I don’t know. Anybody got some parts or recommendations? @CowboyBob @Constabulary @jimi @Wizcrafts

Machine is back at the mechanic, we’ll see what they say. Would be interested to hear what you say about the adjuster not going down further after lengthening slot though @CowboyBob? Also seems like it started with bigger stitches and got smaller after using for awhile

Thank you @jimi @Wizcrafts @Constabulary @CowboyBob @CowboyBob.. I just filed out the slot about 1/4” but the stitch adjuster piece still won’t go any lower? The motion of the feed dog looks like it would make at least 1/4” stitch, but it’s about 3/16” max, and then if I see uneven material it likes to shorten up

@ScottWolf Excellent! Thank you so much, exactly what I was hoping for
