maybe you can post some links I guess you mean GUETERMANN threads (or in german GÜTERMANN) https://guetermann.com/en/

here is a manual that will work for the 171 subclass too Singer 29K71, 29K72, 29K73.pdf

You can make the aftermarket ones work. I did that a few years ago on a 29K1. You may also need the feed motion Ring if your is worn. I have compared the parts here: https://leatherworker.net/forum/topic/60554-29k1-pre-christmas-barn-find/?do=findComment&comment=390874

I found something: You have to loosen Screw D before you adjust the stitch length and tighten again when done.

see above post, I just edited it. Maybe the parts lists help to figure the function. Or maybe the REXEL Co. can provide a manual. I´d check with them. This is from a list I downloaded

I would tilt back the machine and check what the allen key is doing... EDIT: You can download parts lists here. Maybe they help you to figure the function. https://rexel-com-pl.translate.goog/content/33-katalogi-minerva?_x_tr_sl=auto&_x_tr_tl=de&_x_tr_hl=de&_x_tr_pto=wapp

you will not find many oz measures in the EU. Grams per meter or square meter is more common. https://www.esvocampingshop.com/de/outdoorstoffe-zeltstoff/baumwolle/ https://www.stoffkontor.eu/stoffe/canvas/ https://www.stoffe-zum-leben.de/köper-canvas-segeltuch-zeltgewebe/

So how much speed reducer reduction will this motor / needle positioner now accept? 1:2, 1:3 or even more? Does it matter how big the motor pulley is? Usually these motors comes with ~75mm pulley but most LW swap it to 40-50mm pulley. I´m just a user but not an electronics geek so this question may sound stupid (maybe not). Is there (probably) a way to adjust the "reduction acceptance" (I have no other word, sorry) in the motor management menu? That would be a great feature.

looks like a plain drop feed sewing machine but a blurry 7 second video is not very helpful to clearly ID a sewing machine. Do you have a link to the full length video? BTW I would open a new topic for this request cause this clearly is not a 441 type leather machine

You are using a fairly thick needle for a fairly thin thread as it seems. Check this needle thread cart for finding the right needle / thread size combination: https://www.tolindsewmach.com/thread-chart.html This is a GA5-1 Chinese made machine - basically a modern version of the Singer 45K Here is a manual and parts list, hope this helps : 06_Techsew GA5-1 manual.pdf Techsew GA5-1 Parts.pdf

Global was probably the seller / distributor of this machine but not the manufacturer. They also sell used machines. I would assume a Minerva 72401, 72405 or something in between. EDIT: kinda like this one (scroll down): https://maszynyobuwnicze.wordpress.com/maszyny-szyjace-2/

lowering the needle bar just a tiny bit sometimes helps EDIT: BTW maybe this video by LW member UWE helps to figure issues with reverse:

We do not know the robe or the size of the piece or thickness of the leather or what it should look like when finished but generally sewing a thin layer of what ever onto a piece of leather should be technically possible. Why not?

or as a dealer / distributor to sit down for 1 or 2 hours and compile one. That would reduce customer headache and questions - I guess.

We do not know how your machine is set up and if you have a circuit breaker on your machine or not. No matter what when you leave an (especially older) electric deceive plugged in I would recommend a circuit breaker or a power strip equipped with one.

So when your bobbin is empty and you replace it you have to pull up the bottom thread, right? How would it work w/o removing the work? EDIT: Huh - looks like the guy in this video does NOT pull up the bottom thread when he starts sewing with his 205RB (Minute 10:00 onward) https://www.consew.com/View/Consew-Model-205RB-1 Interesting - seems to be working. Not sure why but looks like it does. So when looking at the Video I would assume you just change the bobbin as shown and go on with sewing. Seems there is no need to pull up the bottom thread on this machine - for what ever reason.

I´m late to the show here but in case you buy the goods on Ebay then (usually) Ebay charges you the VAT automatically and in some cases even the import tax and forward it to the Gov. Then your seller gets a code he has to write on the address label so the carriers know VAT / Tax is paid. Thats at least what I experienced. Like Ebay or not but when it comes to international purchases Ebay often the easiest way to buy goods from foreign countries.

guessing it is Tennessee Attachment Co. Inc. https://www.tnattachmentco.com

yes, looks like a darning machine.

Well, nothing really new in this video. However - does the needle positioning work in combination with a speed reducer?

Nice find! Roller feet are sought after and accessories are always priceless! I guess #5 is for folding leather strips for reins but I only can guess. Do you know in what kind of leather business this machine was used? Maybe the products they made can give an idea what #1 and #5 were used for. Maybe the 2 bits are custom made but when you browse through the parts list of other 45K machines (different sub classes means different accessories) you sometimes see obscure accessories so that probably is a good source to figure what you have.

The speed reducer probably is the best solution for you. It ads torque and slows down the sewing speed. So at very slow speed you are still able to sew quite very thick materials (depends on your work and material if you need that or not). I have speed reducer on ALL my industrial machine tables / stands.

I do not recall everything cause it was some years ago when I restored. I´m sure everything was apart except the top shaft. I think when you remove the handle there is a set screw behind it... But not I´m really sure... Looks like your foot is stuck in the upper position have you tried applying more foot pressure?

sorry can´t tell from the Video - but some years ago I restored a Dürkopp 18 (no longer have it) but maybe you can see something in the pictures from my restoration or the pictures other have posted and the video in this thread: https://leatherworker.net/forum/topic/76826-dürkopp-18-patcher-restoration-long-journey/page/2/ https://leatherworker.net/forum/topic/76826-dürkopp-18-patcher-restoration-long-journey/?do=findComment&comment=517817

I do not know the the size but if it is easier just tap a new thread - I´d go that way if you have the tools
