  1. What in particular are Deutsch Hooks? Do you have a picture?
  2. Chart in the manual says up to #26 needle. But I seriously doubt that #26 needle where available for this needle system because of the thin shaft (below 2mm). And I doubt the thick thread would pass the gap between hook and needle plate w/o problems because the machine (at least mine) has no bobbin case opener. Later machines have a bobbin case opener (see manual I sent you). Realistic is a #22 needle and 138 thread max. I´d say. But I usually run #92 / #96 thread in this machine. The availability of system 128 needles on my side of the pond and the condition of the original needle bar lead me to the idea of changing the needle bar. So now I´m able to use "common needles". But that required modifying the machine. I had to install a longer needle bar guide on the upper end because the "new" needle bar was a lot shorter than the original needle bar. The majority of my machines are using 135x17 needles and therefore the decision was easy to set up this machine for 135x17 as well so I do not have to stock lots of different needle systems. EDIT: I have to correct my self. I just have checked an old needle catalogue and it states #26 where available for system 128 (decades ago...). Does not make much sense IMO but well, thats what the catalogue says. I stick to my opinion that 138 and #22 needle at max. is a reasonable combination. But he limitation is pretty much the size of the needle hole in your needle plate.
  3. I have a manual for an early 51w meanwhile (came from a LW member) but it is not exactly for your (our) machine(s) subclass but anyway it is a usable manual but has some technical differences. File is too big to attach here. Please send me your email address by PM if you are interested. I own the 51WSV2 UWE has liked to. Very decent machine. Of course not the latest technical craze but hey forming a thread knot has not changed the "last years" so mine really works very well, I´m pleased. However I made several technical changes like different hook and different needle bar to accommodate a more common needle (137x17) and so forth. I also found new made feed dogs and needle plates that fits this decades old machine. I also increased the stitch length but I explained all that in the above linked thread. This parts list should be quite close for your machine: Download Link: Singer 51w25 to 31 Parts list
  4. DBx1 and 1738 are the same needle. So when a lot of needles are braking there seems to be a technical problem. Leather point needle in this system are : 16X257LR / DBXF2 / 1738LR What means "top is too narrow"?
  5. Do you have pictures of that machine? Not all Class 67 where triple feed ("walking foot") machines they came as needle feed + drop feed and roller foot machines as well. So before you make the trip some pictures may help to ID the machine.
  6. Most important - check the condition of the timing belt - changing it is a pain!
  7. If it was my machine I`d order some "common" needle systems for testing (like 328, 794, 1000) in approx size 180 or 200 and test them in different needle holder positions. This of course is trial and error and no one knows if any of the needles will work. Another option is you look for some rigid / stiff 2mm - 3mm round bar / round material (depends on how wide the needle hole is) for inserting it as a needle substitute. Make sure it is not hitting parts somewhere. Shove it all the way up into the needle holder. Then rotate the hand wheel until the tip of the shuttle meets the needle substitute in the middle of the "needle" and make a mark with an Edding or similar where the shuttle tip meets the needle. Test this in all needle holder positions. Measure the distance from top of the "needle" down to the edding mark and with this measure we can "try" to find a needle that "could" probably work. This of course is not a very precise method but you do not have many options since you do not have an original neelde. Threading the shuttle should be fairly easy to figure and for the top thread path I guess I have a manual of an older Adler II flat bed machine that should work for your machine as well. BTW - just wondering is the shuttle carrier rotating or oscillating. Also if you don´t mind please post some more pictures of the machine in full view form all sides and some detailed pictures of the external parts. Can´t be wrong to have some documentation for the future. Does your machine have a bobbin winder?
  8. So when I look closer at your needle holder it appears that it is height adjustable and probably could take shorter needles / more common needles as well. Can you take a picture of the opposite side of the needle bar please? In best case you may be able to reposition or maybe modify the holder to accommodate common (modern) needles like the 794 or others.
  9. Well question like this have been covered probbaly a dozen times. Thats quite a wide range of material thickness from 2x 2 ounce (together approx 1mm) to 6x 4 ounce (together approx 15mm) So you either end up with (at least) 2 machines or you rethink your material thicknesses. You really want to sew 15mm (take a ruler and check) or is it rather less? It´s less, right? Layers do not matter really, the total material thickness matters. New or refurbished doesn't matter in the end. You can have new machines which are poorly set up / do not suit your needs or you can have a refurbished machine which is set up perfectly for what you want to do. That often depends on your dealer or the seller. Can´t be wrong if you check with dealer who is specialized in leather sewing machines. Machines often look the same but can be set up for different purposes. If you buy used from a private seller always test the machine with the max. thread and material thickness you want to sew. But keep in mind the motor matters a lot. It´s not only the machine that has to suit your needs, the motor is very important too. So it can happen that your machine is great but the motor sucks (too fast, not powerful enough...). Since you like UWE´s FBA - have you checked with him if he could offer you a proper machine? Just an idea...
  10. Excellent! Different story - has your 341 a small or large bobbin hook? Looks like a small bobbin as it has no cap (just curious).
  11. Good Lord A post bed machine made by KOCH (later Koch´s Adler, then Adler, nowadays Dürkopp-Adler) but I do not know the model. I only can guess - I assume it is a "KOCHS ADLER - Sattler Universal Class 23. If that is the case (I only can guess) then the needle system is 580 / 585A. System 580 is a ~ 10,5cm long needle but it is obsolete. As Jimi said, pictures are too small to tell details. Most likely the flat bed version of this machine were either the Adler II or Adler III. H. Sackmann appears to be the dealer the machine once was bought from. Do you have the shuttle hook (see pictures 3,4) and maybe a bobbin? Open the cover plate on the post and hopefully the parts are present. If present please post some pictures. If the the parts are missing (or maybe they are in the drawer?) there is almost no chance to find the parts, I´d say. This is what I have cobbled together from my records (see pictures)
  12. I read prices of up to $600 but that could have been Aussie Dollars. Right now one is on ebay for 499 GBP but yours appears to be in better condition (but I would clean it anyway) but I don´t think the one on Ebay will sell for that price. https://www.ebay.co.uk/itm/Original-Bobbin-Winder-For-Pearson-6-Harness-British-United-Leather-Stitcher-/264340833603 If you want to sell it fast I think a fair price is $300-350
