Spray the needle with silicon spray and see if that helps glenn

shut machine off. Unthread both needle and bobbin. see if the pedal is sticking. pics or video of it running glenn

I would check the specs on the Juki. I do not think a1541 can sew 1/2" thick material. I have a 1508 and it struggles with 1/2" thick material. I think you will need two machines. The Cowboy 3200 might be your second machine. It sews heavy leather up to 5/8" glenn

Titanium coated needles cuts down on the glue sticking to the needle! glenn

we need some pics. glenn

Weronika, Ok A hook is available on Amazon for the 11-3. However, I think it is for the large bobbin. You may have to take your hook out and see about getting it rebuilt. The key is to find out why the bobbin is coming out of the bobbin case. I suspect the locking mechanism for the shuttle in the hook is either worn or broke. There has to be mechanist that can fix it in your area. Machine will not sew with out it. glenn

Either that machine is a 11-17 or the 11-22.

11 parts hard to find. College Sewing? You need a new hook and Presser foot. glenn

One thing nobody has talked about is what Nomex and Kevlar thread do to all the parts in the thread path. It wears thru steel. Know that going in for parts replacement, i.e. feed dog, hook. throat plate , take up lever, all the thread guides, take up spring!! glenn

I believe all three machines are made in the same factory in China. All three companies are good to deal with and Steve, Bob and Raphael are great people. All give great service. To me it comes down to price and the shipping costs. Just my 2 cents. Whoever you choose, they will give you great results!! glenn

Contact Diamond Needle in NJ. They might be able to help. glenn

Take the large spool of thread OFF the spool pin. It puts too much tension on the needle thread as it unwinds. You need a thread stand behind the machine and a fine hole in the spool pin to act as a thread guide. common mistake made by a lot of people with this machine. You will have a very hard time finding the small screw for the shuttle carrier. No longer made and the newer screws are different threads. hole in shuttle carrier needs to be welded up and re-bored. glenn

pics of the machine? glenn

Yep. Everything is slower to get right now. I have that machine. Nice. make sure you get all three manuals-parts, operations and engineers or service manual. glenn

Wont be cheap. I estimate at least $1,000.00US. I upgraded a few of the 767 motor where I retired from in 2017. Each was $1,000.00 plus. Just so you know./ glenn

The only way to tell would be from an older Pfaff parts list. I am not sure what all was changed. glenn

N means newer model. Juki did that with the 563N as well. glenn

nice!!!!! glenn

remove the the belt tensioner. It was need to engage the clutch mechanism and keep the belt tight. Make the clutch mechanism into a speed reducer. glenn

You will need different parts. going form 7mm lift tp 11mm lift. I know you want geniune Pfaff parts. You may not have a choice. glenn

JJN, the jackshaft in the stand is two piece. You have to bolt the clutch part together so that it truly acts like a speed reducer. I sold my Sutton stand to a friend of mine who is putting a Claes on it. Put a nice piece of 1/2" cabinet grade plywood on the top of the stand over the steel top. Looks better and easier to anchor a machine on it. Servo yes. I removed the 1/4hp Dayton motor off of it before he got so that he could put a one piece servo in it. Buy a one piece servo like the family motor, not one that has three pieces to it. Hope that helps glenn

Clone of 225? The Consew is a copy of the Singer 111W155. Max Stitch length 5MM or 7MM? Machine will sew up to about 3/8" depending on the hardness of the leather G size bobbin which is small by todays' standard. these are good machines because of the design. Good upholstery machine. glenn

thanks C

Someone a while ago in Australia was advertising that they had the singer29K foot #8666 being built in China. Anyone remember who that was and if they have any left? glenn

AmyK, The main shaft on top of a Juki is .495-.498". Hope that helps. glenn
