  1. You can gear the servo down. Make sure it has a 45-50mm pulley on the motor. There is a way to make the balance wheel on the treadle stand into a speed reducer. I can walk you thru it. The lobes on your bellcrank are worn. That is why the stitches are so small glenn
  2. You can order a synthetic roller on line from amazon to replace the stone feed roller. It does not grab as tight as the stone one and I found it works better. Not expensive. try one. I also replaced the foot with that roller foot. It works better on thin leather. These machines are touchy so once it is set, leave it. glenn
  3. That is the set up I prefer. glenn That is the set up I prefer. glenn
  4. Not wax pot, oil pot. glenn
  5. Most 441 machines are mounted on an off the arm stand be a H legs or Weaver stand. I prefer that set up up. You want to hang anything off the arm to sew, you will find problems in your current set up. glenn
  6. Only if the thumb screws to mount the binder are hanging down below the slide plate. Glenn
  7. Made that way so feed dog does not lose contact with the binding. glenn
  8. The bobbin case. Machine has no feed. needle goes up and down. makes stitch. you move the item by hand to darn up a rip or hole. glenn
  9. Would not be hard to build this. You need a round shaft, collar, spring, washer, cotter pin. Or call Collier Equipment or Bob Kovar at Toledo sewing and see if they can get the parts. part # rod #223684 collar #227227 screw #200113 spring #206628 cotter pin #202302 glenn
  10. Machines without the P have skiff feed: Feed dog moves back and forth but never drops. Used on the 335-17 binding machine for symmetric feed. 4 motion drop feed is this: Feed dog comes up to meet the needle (1)and inner presser foot. (2)then move to the back, (3)drops down and then (4)comes forward before moving up again. Also called elliptic feed. glenn
  11. You could sew leather with it. glenn
  12. call Manufacturers Supply in St. Louis. They sell clickers. See what they say. glenn
  13. Same manual will work. The 372 has smaller fittings on it like feed dog, feet. It uses smaller sized 134-35 needles. glenn
  14. The 335 can sew #138 thread. You just have to make a few modifications. Enlarge hole in inner foot and feed dog. Pfaff made a heavier take up spring. I would install that as well. I also went to work on the gap and finger on the bobbin area to have more clearance for the thread to clear on each stitch. glenn
  15. Y The speed reducer screws with the sensing in the synchronizer. You can use a servo motor, synchronizer and speed reducer but not all three. I would get rid of the speed reducer. glenn
  16. I would have the piece in the back welded first to see if it will work. Strima in Poland carries a lot of older parts. Check with them since you already have the part numbers. I you contact Pfaff in Germany and see what they have. There is also a guy on eBay in Lithuania that sells a lot of older Pfaff parts. glenn
  17. call Bob Kovar at Toledo Sewing and see if he has any Champion parts. Use to work on them. glenn
