Sounds like a timing issue. I would check the needle hook timing and (most likely) lower the needle bar if necessary. Also make sure the needle scarf is facing toward the hook and needle (as well as the whole machine) is threaded correctly. When the bottom thread is flat you either have a tension issue or a too small needle size or a too thick thread. This chart will help to find the right needle size / thread size combination: https://www.tolindsewmach.com/thread-chart.html Here s a Singer 18 manual. On page 13 (last page) you find instructions for adjusting the needle bar: Singer 18 Manual.pdf This Seiko TF-6 manual should give you some instructions that will work for the Singer 18-3 as well: Seiko TE TF-6, -6B Instruction Manual.pdf

more parts to clean (bobbin winder and other bits). Disassembling the bobbin winder was a little tricky. I feared to break something - fortunately I did not. Lots a tiny bits n screws...

some cleaned parts Interestingly most of the bigger parts are marked with the last 3 digits of the machines serial number.

brownish-bronze - kind of.... no matter what it will never be like the original. I´m aware of that. I only can try to get close. I will not try dozens of shades but will try to find something with an antique touch... or so...

Working on two ends - I started cleaning the deer relief... I hope I´m artist enough to make it look good again

First parts I cleaned are the gear box components and figured a nice feature. The very large pinion (23mm diameter) is held by an eccentric screw. First guess was it is for timing (well it may have a small influence but I don´t think it is supposed to adjust the timing) but as far as I figured (will know more when reassembled) it is for compensating wear on rack and pinion. Why do I think so? Because the further you turn the screw (left or right) the more it pushes the rack against the gear box wall but does not advance the rack much. Lucky circumstance - the rack and pinion are in good condition!

It´s apart and now the fun begins. A lot of parts are literally covered with a crust of dirt and oil. That usually is not as bad as it looks cause the parts are kinda "protected" - but I will see... Cooking "patcher casting soup" @ 8amps in the electrolysis tub - yummy! Not bad for the 1st run but it needs some more.... Figured the Dürkopp paint is a lot tougher than the Singer paint (as on a 29K).

its probably a "example of use" - check with them I´m sure they have what you need.

SIECK in Germany seem to have them for 180€ + VAT - scroll down a bit here: https://www.sieck.de/en/machines/sewing/upholstery-automotive-technical-textiles-decorator/arm-type/?produkt=6728 But for 180€ I´d rather DIY one (if you have tools and stuff)

You are comparing apples and eggs (kind of). The equivalent of the Cobra 26 is the Techsew 2750 and not the 4800 - or not? 26 and 2750 are based on the Juki 341but not 1341 - or not? Not even close if you ask me. The Techsew clone of the Juki 441 is the Techsew 5100. I think you should take a closer look at the machines.

If I had to guess then I would guess your needle bar needs to be rotated by 180° and then the needle clamp installed again as is. You also have the wrong thread guide but that's not an issue I´d say. Why? Cause when I look at your pictures your thread guide seems to be mounted on the left but IIRC on the 32K and similar machines it should be mounted on the right. Therefore (wrong orientation of the needle bar) the clamp sticks out too far to the left. And (I again guess) the needle is clamped against the needle bar for the right - right? Meaning the needle clamping screw directly pushes against the needle from the right but the needle should be clamped from the left by the left inner side of the needle clamp. Let me cross check pictures... EDIT: Correctly installed the parts should be assembled like this (including correct thread guide) - do you see the difference?

Have you fully reassembled it?

Yes, electrolysis and a wire brush for the last paint flakes that came of easily after electrolysis! No, no name on the press.

lager shank diameter than System 88 I wanted to say... Thanks for confirming, Glenn.

Well, they have a physical address and phone number, you find the address on street view, they are on facebook and Instagram. I don´t think fake shops (if you mean that with trustable) would setup these accounts and produce contents. And... well... don´t know where in Toronto you are but aren´t they in the same town as you or at least fairly close? Go check where they are https://www.google.com/maps/dir/Toronto,+Ontario,+Kanada/134+Romina+Dr.,+Concord,+ON+L4K+4Z7,+Kanada/@43.714932,-79.5224992,12z/data=!4m13!4m12!1m5!1m1!1s0x89d4cb90d7c63ba5:0x323555502ab4c477!2m2!1d-79.3831843!2d43.653226!1m5!1m1!1s0x882b2f1245b38ffd:0xfbc36056c8d2203c!2m2!1d-79.5340868!2d43.8164616

You find all technical data and manuals on the DA website (scroll down to leaflets / manuals and download them). https://www.duerkopp-adler.com/products/industrial-sewing-machines/industrial-applications/basic-machines/269 Reasonable priced is a point of view - Adler parts will always cost more than f.i. generic parts for Singer type machines. However KHSew (KwokHing) makes high quality generic parts for many Adler machines. KH parts are available directly or from some dealers and you even sometimes find them on Ebay. https://www.khsew.com/index.php?route=product/manufacturer/info&manufacturer_id=12

While checking the WWW for parts and stuff these interesting presser foot adapter crossed my way. I´m kinda surprised that no one came up with this earlier.

usually the Class 17 + 18 take System 88 needles and some take 332 LONG needles. 332 LONG has a slightly lager shank diameter than the 332 IIRC

A little side project - this press came with the Dürkopp patcher. First two pics are from the classified and show the condition "as found". Holds tools with M6 thread on top and 12mm base on the bottom. Little fund raiser I think... Maybe I´l make a wooden base for it.

First attempts - maybe I have to mix two font types - somehow

I just recalled an old thread where I have posted pictures of another GÖRICKE patcher that once sold on Ebay: https://leatherworker.net/forum/topic/61501-shoepatcher-on-steriods/?do=findComment&comment=403149 I have to take a closer looks at the writing on my machine. Unfortunately very hard to read... EDIT: with some black light and editig... Writing say "ORIGINAL DÜRKOPP SCHUHMACHER MASCHINE" Maybe I can find a close enough font for making a stencil to reproduce that writing.

as far as I figured most (if not all) Dürkopp patchers have the bobbin winder mounted that way. However some were gear driven and some had a rubber tire running on the hand wheel. I will try but I seldom have the camera on hand when digging my hands in dirty machine parts but I will try to shoot some pictures. I have a picture of the stand emblem from different machine (worn of paint but a lot better than on my stand) and I think I will try to replicate it as good as possible but I´m no artist with paint so not sure how it will turn out.

Not sure what your question is? How to remove the black paint or what kind of thread they have used? I do now much about German Luger holsters but maybe at one time there was an order to stain old stock brown leather goods in to black. Like they did in 1956 with the US M-1916 Colt 1911 holsters and other military leather goods (Military Police Equipment f.i.). No matter what I would leave it as is meaning I would not try to remove the black stain. Regarding thread. Common linen thread back then was made by GRUSCHWITZ, HIRSCHFELDER, HOOGEN or ACKERMANN. You sometimes find the shoe and saddlery thread named SEIDENERSATZ (don´t ask me why) but that AFAIK is a cotton thread.

Just for the records - the CLAES and Dürkopp shuttle driver compared. So from "inside the fence" the CLAES shuttle hooks will work in the DÜROPP shuttle driver I guess.

I finally freed the hook cover plate to access the hook and I googled for other Dürkopp patchers and cross checked my records and came to the conclusion this must be a 17-1-2. 17 = Machine Class 1-2 = 1 is for the 38cm cylinder arm (2 would be for 43cm arm) and the 2nd digit 2 is for the hook size medium (1= small, 2 = medium, 3 = large). Interestingly the Dürkopp medium hook is very similar to the large hook that CLAES uses as their #3 or #30 subclass. I figured that cause the Dürkopp bobbins are a tad smaller in diameter. So chances are good that the CLAES #3 and #30 hooks could (probably) work in the Dürkopp medium hook machines as well. But that is just a guess at the moment. Also the shuttle driver basket is very similar to the CLEAS #3 / #30 shuttle drivers BUT they have a different driving pinion (so not interchangeable). Here is a list of Class 17 machine sub classes. Not sure if complete but thats what I have found so far: 17-1-1 sewing machine for shoemaker, heart curve driven needle bar, otherwise construction similar to the class 16-1, cylinder length 380 mm, smallest head, needle 88 and variants 17-1-2 - as class 17-1-1, medium cylinder head, needle 88 and variants 17-1-2 K - as class 17-1-2 with device for cross stitch sewing, needle 88 and variants 17-1-3 - as class 17-1-1, larger cylinder head, needle 332 long 17-2-1 - as class 17-1-1, cylinder length 430 mm, arm of class 18, needle 88 17-2-2 - as class 17-1-2, also adjustable for cross stitches, needle 88 17-2-3 - as class 17-1-3, cylinder length 430 mm, needle 332 long 17-5-1 (17-4) - cylinder length 500 mm, sewing machine for shoemakers, heavy duty, smallest cylinder head, needle 332 long 17-5-2 (17-5) - as class 17-5-1, medium cylinder head, needle 332 long 17-6 - as class 17-5-1, largest cylinder head, needle 332 long 17-10 - sewing machine for hat makers, cross stitch device, cylinder length 380 mm, needle 88 17-12 - motorized machine, 250 stitches per minute, needle 88
