@CowboyBob, Thanks. Even that's a surprise to me. In my limited experience, I thought some of these newer machines were pretty much clones of the Singers. Much to learn, I have.

OK, I wondered if it was something like that. Good, so I don't have to be impressed with Tractor Supply! Thanks for the clarification.

I really hate it when Walmart is the low price leader. But the gallon is a pretty kickin' deal. Now, if only I used it ... Out of curiosity, I looked at my local Tractor Supply (Walmart for rural people) and they show a gallon in stock for 30 bucks. Maybe I should try it out.

Interesting. I would have thought the Singer 111W series would be pretty comparable to the Consew 205's and 206's. Yet the 111W is nowhere on the chart. Maybe they're considered obsolete?

I think these are very, very close.: https://www.amazon.com/Bluemoona-100-Pcs-Leathercraft-connector/dp/B0719H615Y/ref=pd_bxgy_d_sccl_1/141-5165040-7656726?pd_rd_w=irXtr&content-id=amzn1.sym.2b132e63-5dcd-4ba1-be9f-9e044543d59f&pf_rd_p=2b132e63-5dcd-4ba1-be9f-9e044543d59f&pf_rd_r=B6ZZBB2WB44MS9PQXN26&pd_rd_wg=VVWdD&pd_rd_r=48aa5bb2-6032-42ae-8e83-fd8dd907f74c&pd_rd_i=B0719H615Y&th=1 There are 4 options and 1 of them is flat.

Search youtube. I remember seeing some real low tech ways to make lace. I seem to recall a razor blade mounted somehow and a circle of leather being cut spirally. Also a video or two about making round leather that involved rolling wet leather strips out. If you've ever seen a leather treadle belt for a sewing machine, that's what was being made. And second Chuck's suggestion above. The author is Bruce Grant, I also have a copy. You could spend years mastering all the techniques in that book.

Well, you're not getting much help here and I'm certainly not one of the resident experts. I suspect nobody is familiar with that motor. The specs look interesting, if it's a quality motor. Nobody seems willing to even list a price for it, but I do find a used one on ebay for $750! If I understand you correctly, you're not getting a range of speeds when you press the foot pedal. You are correct, there are a daunting number of electronic parameters on that thing and your problem could lie in there. But let me take a stab... All I can think of is to double check the adjustments for the control arm listed in the manual to be sure it has adequate travel (section 2.5, page 3, English section), then disconnect the Pitman Arm and see if you get a range of speeds just by working the control lever by hand. Maybe the Pitman Arm is out of spec or misadjusted. If not, you may just have a defective control unit - assuming there's not something buried in all those settings to make it a single speed motor. I could see that being desirable in an automatic sewing setup. Good luck with it. I'd be interested in the resolution.

Well, until the big dogs stop by and give real advice, the following thread is for a 111w machine, but I think it's close enough to yours that it should get you pointed in the right direction: Good luck with it. I dealt with a similar problem on one of my machines.

The Singer manual Constabulary dropped above says it'll sew a max of 3/16". I'd probably buy it if the price was real right, just because it's interesting. But it wouldn't be in the leatherworking rotation.

Walking Foot - One Needle. Max. speed 1600 spm. For lightweight work in imitation leather; upholstery. Automobile tops. Combined upper and needle feed. No under feed. From: https://ismacs.net/singer_sewing_machine_company/model-list/classes-1-99.html The 78-1 also says "For lightweight work in fabrics only." Between that and "No Underfeed" ... make sure this is the right machine for you. Needle feed and a walking foot should move the layers ok. Unless you're doing only garment weight leather, I just don't see this being useful for leatherwork. Plus that 250 volt thing bears investigation. Is it saying it HAS to be DC? Worst case, I guess you can throw a servo under it for $150 or $200US.

Is the back and the front one continuous piece? And the sides start out as sort of flaps that wrap around to the back? Maybe a picture of the other side would clarify the challenge. EDIT: "This is one piece" means the pattern is a single piece? Not that it's one of a given number you need to make?

WOW! ... Seems to cover it. Do you have a website? EDIT: OK, so a quick search turns up lots of stuff. A better question, is there a main (non facebook/instagram) website?

The video above shows a machine with a speed reducer. The thing we always see here is that Needle Positioners don't work with reducers. Seems like the seller would know what they're selling, but who knows?

I don't think you can build a PID for $35! I'm pretty sure I had at least twice that in the one I made. Here's George wiring up a 240V unit. He also has a 120V video:

The varying stitch length is the challenge for me. Practice, practice practice...

Very skilled stitch work. I recall you saying you used a Cobra Class 4 - it looks like at the beginning of your stitch line you must start with 2 or 3 stitches backtacking to the beginning? Both ends appear to be double sewn, if you started at the beginning, backtacked and then went forward again, you'd have a bulky triple stitch. Am I seeing it right?

Welcome back and God Bless you, too!

You must let one color dry before moving on to the next? I have a hard time waiting between steps on projects.

Looks like a lot of tedious work to get the colors and separation. Nice Job!

I've thought about it but never actually done it. To me, I just thought it'd be better than all that tedious hole punching!

How about installing the snaps and then cutting them out? Either individually or in bulk?

I don't see how die cutting is going to change the stretch when the snaps are installed. That sounds like a material problem to me. Mr. Customer may need to spec different leather.

Nice surprise. Looking forward to pics and a report. We're all living vicariously through you!

I have a 111W153 set up with 138. I have my eye out for something with reverse but in the meantime, it serves my needs.

I have both of those machines but have never sewn vinyl. I'd see no reason either one wouldn't do the job as long as the material to be sewn fits under the presser foot. Personally, among my particular machines, I'd use my 111W153 but the 151 should do as well in most cases. If you haven't read the post linked above (in post #2 of this thread), you really should. Finish it and you'll have a Masters Degree in leather sewing machines. As always, a new post about your specific question might get better replies than resurrecting a zombie thread. Welcome to the obsession!
