What’s the maximum thickness the Singer 29K71 can handle

[JRodriguez]

Hi everyone, I’m selling a SINGER 29K71 on behalf of a retired cobbler. I’m a shoemaker in Australia and I only have used my 29K71 for leather used in shoemaking, probably maximum 3mm thick. A person wants to buy it but they’re asking about the maximum thickness that this machine can stitch. The information I found on the net says 8mm. I tried to stitch two pieces of veg tan leather together (8mm) total and the leather doesn’t even move. The needle is going into the same position all the time. The machine stitches nicely on a lighter weight leather (2mm) but not with 8mm. Can someone’s share their experiences please?

Here's a manual that says the foot rises 3/8" of an inch, so less then that:

Thanks for your reply. That’s what I found too. It doesn’t stitch when I tried it with 2 pieces of veg tan leather together 8mm Thick.

Well, here's over a hundred references, maybe the answer is buried in there. Were it me, I'd let the buyer decide for him/her self so I don't get blamed for any problems.

If you're feeling keen then just sew a few different scrap pieces, of differing thicknesses, together so the buyer can see the results. No excuse then for not knowing.

There's a wingnut adjustment on the back side you need to move to the "H" side.This will make the foot lift higher when it walks.

I have sewn close to 12mm webbing with mine. But thats not what it should sew every day. I just played with some parts setting, no other chnages no grinding or welding or so. And stitches become shorter the thicker the material is.
