  1. https://leatherworker.net/forum/topic/80481-all-things-pfaff-145-info-tidbits-maintenance-etc/
  2. It seemed stupid to buy a whole hook assembly just to get a new guard. As I had a broken saw blade that happened to be of exactly same thickness as the guard, I decided to make a new one. The original was hardened, but I didn't see any reason to harden mine. Furthermore, thin pieces like this can easily distort during hardening. The new guard seems to do its job just fine. While at it I also changed the original 75mm pulley to a 50mm one and added an extension to the control arm to get a bit more travel and thus more control.
  3. Thanks for the hints, I will try them the next time I use the machine. Unfortunately, I have the machine in a place that isn't too close to where I live, so it will take some time. Going around the small pin is something I saw in a video on how to thread Pfaff 1245. Now that I looked at the picture on the cover of Pfaff 545 manual, the pin is not used. My machine is H3 variant and uses 134-35 needles.
  4. Yesterday I visited a small leather bag factory that has been closed down for some time. The owner, around 80 year old lady, is selling some of the machinery and that's where I bought my Adler 69 some weeks ago. This time I bought various pieces of small hardware for bags and some spools of threads as well. In one corner she had maybe hundred spools of thread with a sticker saying "Amann Dominator 7". I took one of those, and then at home googled that it is cotton thread and the current product name is Amann Mercifil. The size doesn't seem to be Tkt 7 (#415), if I put it next to Gutermann Mara 15 (#207) it actually looks slightly thinner (in the picture Mara is brown). Some weeks ago I also bought a Pfaff 545, and finally today I had some time to play with it. I used the Dominator thread as I wanted to figure out if I should buy more of it (the price is very low). However, I just couldn't figure out the thread tensions. In the end the bottom tension was almost none and the top tension was so high that it was difficult to pull it by hand. Still the top thread got pulled to the bottom of the leather. I used Nm 160 needle (=23 needle size). I also tested Nm 140 needle (22), but it didn't make things any better. To make things worse, it seemed that the top tension varied. If I had set the tension so that it was difficult pull, after sewing a little bit it sometimes was easier to pull. But there was no consistency in this. Have I threaded the machine correctly? What should I do/test next? And if it is not yet obvious, I have very little experience with sewing machines.
  5. I received the motors from College Sewing yesterday. It was a fairly easy swap with the old motor using same spacers. Definitely a lot nicer to use than the old clutch motor. I was doing some testing with different speed settings and at some point I hit the reverse and it went all bad then. The needle apparently hit something and got bent badly. A piece from hook assembly got broken as well. To my understanding the timing was right; no skipped stitches or any other problems. So I guess I have pulled the leather in wrong direction which has caused the needle to bend and hit whatever it hit. Another lesson learned: don't try to mimic the pace of much more experienced people on Youtube videos There is an Adler serial number on the broken piece, but I couldn't find anything with that. I will try to TIG weld the piece together. If that fails then the only option is to buy complete hook+base combo, unless someone knows where to get that particular part.
  6. I ordered two servos from College Sewing. Hopefully I get them sometime next week.
  7. This is good to know. Would recommend one with needle positioner: https://www.college-sewing.co.uk/jk-563a-1-220v-750w-1-hp-servo-motor-with-needle-position.html
  8. Thanks. I found the correct pulleys at College Sewing www-pages, but now I'm thinking about getting a servo motor.
  9. Actually since posting I've been looking at servo motors. I had a look at the Jack motors that seem to have 13mm shaft, which is a slight problem. I also found another option that has 15mm shaft (I asked the seller): https://www.ebay.co.uk/itm/1HP-750W-ENERDY-SAVER-SERVOMOTOR-FOR-Walking-Foot-Sewing-Machine-Variable-Speed/264426729590?hash=item3d910fb076:g:zEUAAOSwsMZdQBZV
  10. I need to get a smaller motor pulley for my Adler 69. The end of shaft is tapered. Ebay is full of sewing machine pulleys but they all seem to be for straight shafts. Does anyone know a source for ones fitting the tapered shafts (I assume that this is some sort of standard taper)? Preferable Europe (or China if the price is right).
  11. Quite often when I have bought old machines the previous owners have been quite unaware how to correctly use the machines. These kind of forums have usually been the best sources for information. Now that I don't have to learn everything by trial and error, why can't I leave the foot height to the max all the time?
  12. I did read the manual before I got the machine. The manual indeed says how to change the foot height, however, it does not say why to change the foot height. Being a newbie when it comes to sewing machines I did kind of bypassed that piece of information. I just changed the foot height to the max and tried the same seam I had problems with earlier. Now the machine had no problems to climb over it, so problem solved! Earlier on I also tried playing with foot lift pedal, but that didn't go so well; it resulted in loose threads. I'll leave the technique to experienced operators :).
  13. I have now had my first sewing machine (Pfaff 193) for a couple of years. To be honest, I have used it very little during that time. So the only logical move to make was to buy two new machines :D. I bought an Adler 69 last Friday and then a Pfaff 545 on Sunday. I haven't played much with the Pfaff yet, but did a little bit of sewing with Adler. As written by others on this forum, it struggles climbing over seams. The feed dog on my machine is completely smooth. Would a toothed feed dog (such as https://www.ebay.co.uk/itm/KH-69-R-Throat-Plate-Feed-Dog-for-Durkopp-Adler-69-Sewing-Machine/292474269634?hash=item4418d32fc2:g:UhoAAOSwGW9an2e7) make a noticeable difference?

    Folded Leather

    I received new leather (rolled around a cylinder) last week. No folds and the overall quality of the leather was better than in the first shipment. They even threw in some extra square feet for my trouble. So all is well
