Hi, Yes that is right. The needle plate isnt there at all. I took it away so that the thread loop would be more visable. Im holding the tab with a screw driver to keep it from jamming

I tried to film when the thread loops over the shuttle and when I did some stitches with the hand wheel. https://streamable.com/lgy9r9 https://streamable.com/ufwugw <div style="position:relative; width:100%; height:0px; padding-bottom:56.250%"><iframe allow="fullscreen" allowfullscreen height="100%" src="https://streamable.com/e/lgy9r9?" width="100%" style="border:none; width:100%; height:100%; position:absolute; left:0px; top:0px; overflow:hidden;"></iframe></div> <div style="position:relative; width:100%; height:0px; padding-bottom:56.250%"><iframe allow="fullscreen" allowfullscreen height="100%" src="https://streamable.com/e/ufwugw?" width="100%" style="border:none; width:100%; height:100%; position:absolute; left:0px; top:0px; overflow:hidden;"></iframe></div>

Thank you for the input! I did a calibration according to the 1245 manual. Its slightly better but I still get the loops. Especially when i turn the wheel faster. I dont have any snapping sound as the one you showed Uwe. But might there be something catching in the end? I also suspect that the hook is somewhat worn..

Thank you for the input! Which part of the number is the sub class number? I couldnt really find my number. But I found the letters though. Regarding the leather sewing part I figured that the L would stand for leather. M would be the safety clutch and N doesnt correspond to any number? But I have also read that the binder machines doesnt really sew heavy thread, like the 335. This is #92 and not that heavy I think. I would like it to sew at least #135. Ok I will try and raise the needle bar to accomodate a longer needle and adjust the bobbin så that the needle doesnt get crowded.

Hi all, I Recently got my hands on an old Pfaff 545 and since I needed a flatbed machine for sewing leather I thought this was the machine I didnt yet have. The prevoius ownere hadn't sewn leather on it and did mention it skipped some stiches sometimes which made me think it would be a calibration job more than anything... I might have been wrong. First of all. Is this machine for leather really? The letter on the front made me think so and the big flywheel points to sewing heavy stuff. But then I notised that the feed dog doesn't lift like a four motion feed dog would do.. Is this perhaps a binder machine? (I suspect so looking into the main shaft -images) Second. The previous owner have put 135/5 needles in it. If I switch to 135/35 (Which I think it should have) the needle binds with the shuttle underneath. Tension: And as you see the machine does really poorly with leather work. This is 92 thread. The upper tension is quite high here so something is binding underneath I think. I might need some help here. I have looked at tons of videos and read a lot of threads here at the forum. I can send more images and videos of the set up with the feed dog and shuttle etc. Appreciate all help. Med vänlig hälsning, Erik

Here is some picture of the tension unit. Does it look complete? Also, could you send the manual. I did send you a DM

Thank you. Yes if its not working then I will def argue on the price.

Hi all, So it should roughly look like this https://www.ebay.com/itm/144896567757 on the top parts?

Will ask for photos on this! Also how do I assess if the rest of the machine really is as heavy duty as it should be? Take up lever measurements? (And of course tension unit?)

Should make for a heavier thread then? Anything else I should look out for / check when picking the machine up? Might go next Sunday.

Thanks for the help so far. Realised now that the machine I'm thinking of buying is the Singer mentioned in here. If I do drive up to her and the Koch is in working order I'll try to snap some videos to you for your record!

Thank you all for the efforts. As I said Im not about the sew a saddle but rather some leather bags so it should at least sew through some layers of 5 ounce leather. I will ask the seller to measure the bobbin. She did provide this image of the shuttle and needles earlier. Although Im beginning to suspect that she never has done any sewing on it so I would take the needles with a grain of salt. Perhaps part of why the threading situation isnt working.

12 mm would be absolutely max. Most likely around two or three layers with 5 ounce leather (6-8mm?).
