shoepatcher

thanks Bob glenn

30" throat. big or small bobbin? glenn

Do not retap hole. I myself would take a Dremel and enlarge the opening in the synchronizer clamp so screw fits. I have done it in the past. Dremel with drum sander attachment. The clamp metal will be softer than the screw head. The screw is spit so that it holds snug in the hole in the shaft. It will take a little work. Have a micrometer near you to check the screw diameter and hole in clamp. glenn

DLee. You can go to the 29K72 book. Almost same machine but for a few parts. They have and exploded view of the machine. I may have one. Let me look. glenn

Contact Ryan at Ryan's Saddlery. He is the importer in North America for Cowboy. glenn

That is one from the first year they came out. I have that exact model. About 13 months after they were introduced, Juki made a few changes and the new one was a 1508N. glenn

It is not threaded correctly in the video to start. If sewing with #69 thread. #18 or #19 needle is best. One thing not mentioned here is the take up spring. Pfaff made a heavy and light spring. You are using #69 thread, I would go to the lighter spring. The one in the machine is for heavier threads. Check to make sure the take up spring is threaded correctly in that when going around the tension mechanism that after it, you hear a click when you pull the thread around it. That tells you the thread has cleared the curved finger in back. glenn

Not threaded correctly to start

you need needle system 29x3 or 135x17. glenn

Actually it was on for the long arm big bobbin Singer shoepatchers 29K 55, 60, 72, 172. glenn

I would take the foot to someone with a 3D printer and have a prototype made out of plastic. Once that is done and you are satisficed, there are people out that with 3D printers that can print in metal. Cheaper thatn having it machined. If it works, get a couple made. People looking for the feet. glenn

Glad you got it going. I have a operations manual for the 30-1. glenn

The Singer and Adler use 7x1, 7x3 needles or 794. You might move to the needle system 1000 or 1001 needle system. The make needles up to #300 if I remember correctly, maybe even #330. It would mean retiming the needle bar. Thread above #556 may be harder to find. glenn

Durkopp uses system #88 needles. The System 332LG or #332LLLG which is the leather point will work. You may not be able to get the #332lg needles in the needle hole because they have a shank size of 2.0mm. The #88 has a shank size of 1.90mm. Both needle systems the same accept for the diameter of the shank or top of needle. I have books on the #18 Durkopp class shoepatcher but one is in German. The 18 class that you have has a stationary shuttle. The 17 class has a rotary shuttle. both are good machines when operating. Do not put that big spool of thread on top of the machine. It will screw with your top tension. glenn

that mount is and Efka motor mount. Nice job C! glenn

yes contact Bob Kovar at Toledo sewing glenn

OK I have a DA 669 eco. great machine. The one problem I had since I sew mostly with #138 is this. Adler borrowed the entire hook from their 367 machine since it was a horizontal hook in the flatbed. The largest needle you can use with it is a 150. Try finding that size. normally #140. I use a titanium coated #160 for what I sew. To use it, I had to remove the bobbin case basket. I took both carbide and diamond bits and enlarged the slot the needle goes down thru. i then went over it with silica carbide flat Mitchell cord to polish it up. I now can sew with either a #160 or 180 needle.no problem. No more frayed or cut thread. Why DA did not enlarge the slot from the beginning is beyond me. The 669 silver line with trimmers has a larger slot in it to accommodate the #180 needle. If you sew with #138 thread, you need to do this. I also think that leather made be a bit hard for this machine. for the hell of it, wet the leather and try sewing it and see if you still have tension problems glenn

For what you paid for the machine, Sergey should have an operations manual available. Juki or Seiko make one anybody know? glenn

that is correct as to loosening the shuttle carrier adjustment. the long drive rack in the horn is bent and is supposed to be. they also went to a different cam bolt and nut on the end and eliminated the pin like fount on a 29-4 can we see pics of the long bottom drive rack out of the machine and the shuttle carrier out of the machine? glenn

I got the springs guys. glenn

Probably the revolving bush #8573 is what normally wears. The needle bar hole normally wears left to right, not up and down. Screws worn? the revolving bush washer can be replaced. They are available. glenn

Contact Shoe System Plus in New York or Gateway Shoe in St. Louis. They should have manuals. glenn

Feet are out of sync. There is a big screw on top that you loosen. It will release the inner presser foot. Put inner presser foot all the way down until it touches the throat plate. Turn balance wheel until needle enters the inner presser foot and tip is at the very top of the throat plate. Now tighten the big top screw. Both the height of the walk of the inner and foot should now be the same. If not, you may have to fudge the the point the needle just before it enters the feed dog or just after it starts to enter feed dog to get the walk of the foot the same. glenn

It is in reprograming the perimeters of the machine. QUICK Rotan was bought out by Pfaff many years ago. No longer made. You might contact Harvey at Dunlop Sales Electronic services division. They rebuild them and probably have manuals on the motor. He has been helpful to me in the past and rebuilt a quick motor for me. glenn

ok D class for Heavy, L for leather, M for safety clutch, 6 for max. stitch length of 6mm. No P for 4 motion drop feed, No S for sewing cloth. How high does foot lift? H2 were 7mm. H3 were 11mm, H4 were high lift 14mm. Old one because it is black in color.
