I have 5 Durkopp 17 and 1 18 to restore. Use lots of penetrating oil on it. May want to put it into an electrolysis tank to de-rust it and get parts loose. Constabulary uses the electrolysis tanks a lot with great results. Looks mostly all there. Is there a hook and bobbin in it? Great project to pursue. I have manuals on it. glenn

The 29K57 is a rare one. It came out after the 29K51-56 series and before the 29K58,60,62 series. I have one. Certain parts will be almost unobtainable. If your hook is a generic one, it may be a few thousands too big or small over an original one. You got any manuals on that particular model? I would be very interested in getting copies if you have them. I have original Simanco hooks if you need one. glenn

No the first pic is 4 motion drop feed. In skiff feed, the feed dog goes back and forth but does not drop. glenn

Constabulary on this site rebuilt one years ago and there is a post about it. Also, there is one I think on Utube as to how to sew on it. In my opinion and I rebuild shoepatchers, that one needs some serious cleaning before I would attempt to sew and time it. It needs cleaning in the head and thread path. Too much grease build up and old oil on it. I think I have a manual on it. On a good note, You have the slide on table and drawer which are rare to find these days. glenn

Need a pic or to of the machine please

It has skiff feed instead of 4 motion drop feed. H4 high lift and possibly a 10 mm max. stitch length stitch length which were special order and rare. It should still sew and feed well. If it does indeed have a 10mm max. stitch length, buy it and buy it NOW! glenn

I think it is a 29K58. Nope it is a 29K70. I can see the tag. Plus it has the older take up lever adjustment. glenn

The best machine out there is a Claes. These are very expensive new. Used ones are available but they start about $3,500.00 just so you know. I would try to buy one of them. glenn

parts available for 30-10. not so much any more for 30-1. glenn

Call New England Needle and Diamond Needle to see what they have in stock. glenn

I know. parts are for the old grey paint style. glenn

Durkopp Adler still has these parts in stock. Get a hold of Durkopp Adler in Asia. You got a parts list? glenn

Model 313 Pederson. early model. They came out with other models later . The 317 is the Rapid E. Considered the Cadillac of curved needle sole stitches. These machines all made in Denmark. glenn

video of it sewing please. Sounds like you may be a tooth off on the timing belt, . glenn

Steve at Singermania in Australia passed away in 2020?? glenn

It may sew with #207 on top and #138 in bottom. only way is to try it. call Bob Kovar at Toledo Sewing. He will have needles and bobbins. glenn

the original bases were paint black lacquer or japanned black and metallic gold paint on the fretwork. glenn

Never in my 45 plus years of sewing have I had the length of the stitch affect the tension. Sorry. glenn

Go to a #23/160 needle with #138 thread. All I use and I sew almost the time. I also use titanium coat needles which are the best! glenn

The length of stitch should NOT effect the tension. If the needle hole is too small, that will affect the stitch tension because knot will get hung up on the bottom of the piece you are sewing. glenn

Check with Kwok Hing and order feet for them. They are in Hong Kong and ship the States. Very good quality. You buy genuine Pfaff, they will not be chea. glenn
