last thing I could imagine is that the adjuster for the thread take up lever it too far in and is causing a bind. See page 11 in the manual. But I only can guess - hard to tell what is going on when not in front of your machine.

One thing I notice in the video is that your stitch length adjuster is set to the shortest stitch length as it seems. Lower it (longer stitch) and try again. See above linked manual page 10. There also is an adjuster for sewing different material thicknesses. It should have the marks H, M, and L (High, Medium, Low) or just H + L. Looks like it is set to the highest foot lift (not sure though). Change the setting to medium or low foot lift and try again. Manual page 12. Hope this helps.

Adler 220 and Singer 144 share a lot of parts. However the Singer 144 is older than the Adler 220 so maybe Adler "updated" some prats. When Singer was going down Adler even manufactured the 220 for Singer which they marketed as Singer 144A. It´s probably the same as for the Singer 111w which is more or less the grandfather of may newer triple feed machine made by Seiko, Juki and so forth - they share parts but are not 1:1 clones. So it depends.... What parts are you looking for? Maybe the question in easier to answer this way.

Interesting motor! But seems they are kicking around promotion for this motor for maybe 2 years but yet no source to buy them or what? For a reason?

This may help you: https://www.thethreadexchange.com/miva/merchant.mvc?Screen=CTGY&Category_Code=prewound-bobbin-information https://www.thethreadexchange.com/miva/merchant.mvc?Screen=CTGY&Category_Code=Prewound-Bobbins But I do not know sources in AU

A IMO more important question is to ask if he can provide a binder attachment that suits the bindings material you want to use. I guess you want to use a leather tape for biding edges. So the thickness and width of the biding material matters as well as the thickness of the edges you want to bind.

No offense but better post pictures of your machine or a Video instead of having people to download a parts and walk trough lists to figure what parts you mean.

Make sure your screw driver really fits the tiny screw slot. If the screw is seized / gummed with old oil apply heat with a heat gun and try again. Or try a micro gas blow torch or a blow torch pen. https://www.ebay.com/itm/176252788614 or similar

IIRC sole folks from Downunder imported one or two of them a while ago. But I do not recall who it was. EDIT: Found some related threads: https://leatherworker.net/forum/topic/94574-tsc-441-clone-from-china/ https://leatherworker.net/forum/topic/56853-buying-keestar-sewing-machine-441-directly-from-china/ https://leatherworker.net/forum/topic/70913-441-clone-factory-name-and-location/ https://leatherworker.net/forum/topic/88115-usa-import-of-441-my-story/

when heavy thread is breaking it also could be that the hook tip is piercing the thread. A reason can be that the needle bar is set a bit to high (they sometimes raise a bit with the time f.i. when sewing a lot of hard materials or hit a hard spot or the needle plate). When the NB is set to high the hook tip probably pierces the bottom of the thread loop. So I would check the needle hook timing and even when you think it is set right try to lower the NB a tiny bit. Just a suggestion - maybe it helps, maybe not. I cannot see when the thread is unspooling in the video. But I would control the travel of the check spring. The travel of the check spring should stop when the needle tip is above the needle plate or above the surface of the material. I guess the the tension unit has a rest for the check spring that can be adjusted.

Not sure how wide they were spread internationally. But if no one can help here check in the German sewing machine forum: https://www.naehmaschinentechnik-forum.de/search.php?keywords=Phoenix+249 Pretty sure a lot folks there are using 249 and similar machines

maybe raising the feed dog could help.

Just from looking at the pictures IMO this machine rather is a clone of the Seiko SLH 2B with some differences but I guess the feet of the SLH should work. Singer 7 parts may work as well since the SLH is the "predecessor" of the Singer Class 7. Another option for parts is the Consew 733 (same as the Seiko). https://www.college-sewing.co.uk/parts-by-machine/seiko-sewing-machine-parts/seiko-slh-2b-2b-1-2b-fh1-parts EDIT: I just checked ebay for Consew 733 and found this https://www.ebay.com/itm/163280314467 Looks similar to what you are looking for. I would check with the seller because of the meassures.

It´s a CB Hook machine. I assume its is 1920´s - 1930´s made. It was replaced by the Pfaff 25 and later by the Pfaff 28. This site will help you to figure the date: http://needlebar.org/main/dates/pfaff/index.html

The Pfaff 23 is similar to the Singer 17 and Adler 48. This 23 Model has a reverse function which is quite rare. The machine either has a long beak shuttle or a CB hook but I guess its the long beak shuttle here. If it has the LBS then the bobbins are fairly small and do not hold much thread. Test if the bobbin winder works and if you can adjust forward and reverse stitches. Does the machine come with other accessories? Check what is in the drawer and tin box. The big flat bed attachment is very nice!!! I have a few files incl. an English language manual for the Adler 48 (similar machine) and a German language manual for the Pfaff 23 and so forth. Hope this helps. Check if the needle plate (needle hole) in good shape and nothing is broken. If broken do not buy it cause the needle plates are hard to find and if you can find them they are very very expensive. Only source I ever have found for a needle plate was this (same NP as for the 23 - nuts price) https://planetecouture.com/en/needle-plates/6024-plaque-aiguille-pfaff-28-rfrence-91-046-280-04.html IIRC the Pfaff needle plate cannot be replaced with Singer 17 parts.

can´t help with he model but it seems to be a needle feed only machine and the part on the plate kinda reminds me of a BUSMC #6 HM but this machine here has a barrel hook as it seems. I would guess it is a "modern clone" or modernized model of a BUSMC #6 HM - kind of. Do you have pictures of the back side? Quite interesting machine!

w/o having seen pictures usually the hooks for thinner threads have a raised tip on the hook gib.

check the number on your machine again - maybe you missed a digit

Reminds me of a Singer 132K6 when looking at the feet, thread lever, needle plate and tension unit but machine seems to have a barrel hook (see bobbin winder). Regarding Sibyer I found this: http://www.sibyer.com/wap/cp.asp Use google translate Crap - they have every sewing machine you can imagine - sewing machine wonderland

Picture does not tell much. Bobbin winder is missing and 2 screw of the stitch length scale. Not a too big issue I guess (w/o knowing more details). I´d put a plate where the oem bobbin winder was and buy this table mounted one. Thats the most economic way I guess. https://www.ebay.com/itm/143422223667

For Pfaff: http://needlebar.org/main/dates/pfaff/index.html

There is also a long one piece lifting lever that Seiko, Consew or Juki sold with their Singer 111 / 153 clone machines... https://www.ebay.com/itm/384985925128 You may find it at your local or preferred sewing machine dealer as well. I have one on my 111G156 as well but it is not connected to a pedal atm.

if you have the parts numbers any Dürkopp-Adler dealer in the Neatherlands should be able to get them for you. If not check with Liersch, Zieger or Sieck in Germany https://liersch.com/ https://www.np-z.com https://www.sieck.de/

https://www.districtleathers.com/products/transparent-horse-hide they have other fancy leather too I have never seen.

It sounds quite interesting as it would eliminate the pendulum effect of the needle bar but I´m not sure about this.That would mean the pivot point of the rock frame is NOT on the top side of the rock frame as on almost most other triple feed machines. I think I have to check the 1341 parts list for that....
