Well, I've been hoping one of the experts would weigh in here, but I'll take a shot at it. On my Singer 29-3, there's a similar setup that controls how high the foot lifts. I'm thinking it's the same on your machine, but I'm pretty sure yours is a different brand. I have to go resize a picture. I'll come back and upload it.

@Appaloosa, have you taken that control box apart and looked in it? I'm on team Constabulary, I think something rattled loose inside it.

Does that one fold up from the bottom to close the toe? Quite nice!

Simple, minimalist design and skillfully executed. This is at least your 3rd post showing the importance of practice with minimal tools and skill building over a shop full of the latest big name tooling. Every beginner should read these few posts before they start filling that Amazon cart. Thank you for posting these.

I'd take the tensioner apart and see if there's a burr or something else going on. Funny it would rear it's head right at a bobbin change, but it's worth a look. Another thought, make sure it's tight starting at the tensioner and not further along the thread path. Be sure where the problem starts.

Nice find @ChibiMethos! I don't see a copyright notice so I grabbed it and added it back to the original post. Thanks for your help.

@Stonehouse Leather Works I moved you over to The Marketplace under Business and Estate Sales. Nothing else seemed quite right, it looks like you're selling a business or part of one. Good luck with the sale.

So far, so good. We still need your asking price. See rule 5 below. https://leatherworker.net/forum/forum/70-announcements/ @PiggyPete

Those are called "hollow ground" in case anyone didn't know. Makes a huge difference when paired with the right size screw.

@PiggyPete Forum rules require shipping info (your willingness and cost) and an asking price. You can just add that in a reply. Thanks

Thanks. The seller site is a little thin on info. I'd have believed you without the movie ... On a related note, @Johanna, this is a 7 meg upload. We've seen a couple of large uploads lately. Has the file size limit been raised?

Maybe a dumb question, but does the feed dog(s) go up and down? Because "binding machines" we've seen here have feed dogs that go back and forth, but flat. Both the videos for that machine show it binding. Amazing you did this during the giant tariff kerfuffle and seem to have been unscathed. I wonder what all the fuss was about ... I've been reluctant to order anything very expensive from overseas even before the big kerfuffle, not wanting to get hit with some kind of import duty surprise.

Good call to stay away from the Heavy Duty. I'll let others chime in on the 29. Maybe you could mention what size thread you'd use and the max thickness you might want to sew. That'll have an impact.

Here's a link to a parts list: https://consew.com/Files/112347/PartsBooks/2457R-1A.pdf It shows optional cams for funky stitches, so if doubt it's heavy enough for the kind of leather we sew around these parts.

@dikman, I hear you. On my 151 and 153, they'll punch through whatever fits under the presser foot with a half horse servo and a speed reducer. Without the reducer it starts to get dicey at about 10 ounces of veg tan. She's got the servo,so we'll know pretty quick.
