you can also buy quite cheap tool sets and I doubt this one is of lesser quality than what Tandy sells. But as always you never know before you tried it. https://www.ebay.de/itm/373492308811 https://www.ebay.de/itm/313620260332

maybe a slicker for the shoe / cobbler trade

what diameter and height have the bobbins? Could be Adler 220 or Singer 144 and the like.

Thomas - are you sure all parts / components in the lower tension unit are present - I´m not sure but it looks incomplete (see picture) and maybe the spring is too weak as well? This is a TU from a Singer 45K but the components are the same (though not interchangeable) - see link: https://leatherworker.net/forum/topic/87669-missing-lower-tension-assembly-on-singer-45k58/?do=findComment&comment=598650 The 2 disc are not just plain washers the center hole has a flat side (just as the post) to prevent the discs from spinning. Then tension comes from the friction between the pulley and the felt washers and the 2 disc so when the 2 discs are spinning you have less friction meaning less thread tension. Thats at least my understanding of the lower tension unit. EDIT: However - on my 45D91 I added a heavier spring to the top tension and control the thread tension that way. I also don´t do the 1.5 time wrap but thats trial and error just figure what works best for you. Nice setup BTW - i like the color of the stand!

well you have a 50/50 chance so should be quite easy to find out. One way is shorter the other way is longer... so... But usually toward you lengthen the stitch.

I think Cowboy CB105 / Cowboy CB2500 is the GA5 type you are looking for. Other than than Singer 45K, Adler 5, Adler 105 are in the same class.

without knowing at what stitching you looked I would say a needle + awl sewing machine like the Campbell Randall https://campbell-randall.com/product/model-campbell-lock-stitch

the website no longer exists. Sorry!

In my has I only had to adjust the needle bar height but it is fiddly because the NB is governed by a V shaped cam but I got it back to live and it worked very well. But when your needle bar is technically okay you do not need a new one just for using 135x17 needles. My old NB worked with 135x17 w/o problems. I only replaced it cause it bent when I tipped over the machine. sure. I have used needle sizes up to NM 140 but again if you current NB is functional you don´t have to replace it just for using different needle sizes. A 34K11 is a much much heavier machine than the 34K2 or 34K5. it weights approx twice as much as a 34K5 and the 34K11 (system 328 or 214x1) is using a needle system that the 34K2 or 34K5 cannot handle. The 328 needle is much longer it does not work in the other 34K machines. How thick is your "thick leather" - in total, not single layers?

Maybe the motor has a poor electronic brake. Honestly if someone puts a disclaimer like this in a description I would not buy it. They may not be available in the US but I love my two JACK 563 servos very much. Oldest works flawless since 2014 on a Singer 111w156 with speed reducer and the other on a Singer 45D91 with heavy flywheel and speed reducer.

yeah - now it´s gone - no surprise at that price - sorry! EDIT: aaaaah, well... You have to be logged in into facebook as it seems - I still can see it when I´m logged in.

Or maybe not looks like it is still available. The roller foot alone sometimes goes for that money, not speaking of the very nice stand and well, the long arm machine.

Bargain Singer 133K17 /as it seems) with loooooooooooonh arm and drop feed + roller foot in NI. https://www.facebook.com/marketplace/item/590592535716845/

Maybe this manual is better: https://www.manualslib.com/manual/1105531/Consew-227r-2.html Same machine - different brand. What Uwe said - if it has a servo motor then you usually can change the rotation direction w/o problem - hope you have a manual for the motor. If it has a clutch motor you most likely have to change some wiring to change the rotation direction.

That is a single needle CW-8 clone - see my 1st post But the 387 has a Singer "211 upper" but the one I shown has a "111 upper". I´m aware of all the Consew and Seiko models but haven´t yet figured the name name of THIS PARTICULAR machine shown in the 1st post. I´m sure it is a Seiko built machine with Singer label (not unusual) but... which? Considering this model Singer 153-B8B (which is similar to the Seiko CW-8, Consew 227 and the like) then logically the above machine should be a 154-B8B. But zero information out there as it seems. https://for-sale.yowcow.com/listing/135450024/ EDIT: For the records the pic of the 153-B8B

it´s a 1 thread chain stitch as it seems

I´m a bit stuck.... I have access to a Singer double needle cylinder arm machine with walking foot and reverse (converted to single needle as it seems) - but I cannot figure the model. Should be easy, right - cause its Singer... It`s not ... So to my knowledge it is a Seiko built machine (hand wheel + reverse lever + #tag helps to ID)- so the CW-8 (similar to Consew 227R) could be an option but the CW-8 did not come as a double needle as far as I figured. Maybe a 154w / 154K model - the 154w103 is a walking foot - but has no reverse and different stitch length adjuster. When putting the 111 / 111G subclass in relation it COULD be a 154w156 - but it did not exist AFAIK. I also cannot find anything among the 154B or 154U... Maybe someone else knows more - I can´t figure it. I´m not worried to run this machine cause it seems a hybrid between 154w103 and Seiko CW-8 (kind of) but I just wonder what "the name" of this machine is . Some pictures (only pics I have):

Stitches become shorter the thicker the material thats because of the pendulum effect. Maybe this thread is interesting fro you: https://leatherworker.net/forum/topic/87658-official-stitch-lenght-for-singer-29k-is/ I can sew close to 12mm with my 29K71

This is a Dürkopp 18 but its the same. Picture is from a machine I restored in 2017 (see link below picture). Thats the closes I haven - machine is sold. https://leatherworker.net/forum/topic/76826-dürkopp-18-patcher-restoration-long-journey/page/2/

INCOTERMS are international meaning they are used in all countries worldwide when it comes to freight shipping / forwarding and the like (usually not in the plain postal business) but when a seller chooses DDP you as a recipient / private customer will never take note of it.

CS does not pay me for mentioning them either - maybe I should ask them . Before BREXIT CS was my preferred supplier sadly they cannot (???) deliver to the EU atm. But to be honest so far I have all I need and rarely need anything new for my projects. I know armastore but actually haven´t yet bought from them. Ooouh - seems I have to dive through their 1€ presser foot range - hell thats cheap... tempting...

I had a fiscars rotary cutter - I did not like it blade always released / jumped back when I applied pressure even when locked. I´m now using a KAI rotary cutter - works much better https://www.ebay.de/itm/192411303843 bought mine from CS https://www.college-sewing.co.uk/n5045-45mm-kai-round-knife-wheel-cutter.html

DDP (Delivered Duty Paid) is an INCOTERM and basically means that everything is up to the seller - like door to door delivery with all risk at the seller and the costs of export is also up to the seller meaning they are paid at delivery.

Paperwork says 8KN at 5 Bar (72.5 PSI) but I´m sure the thing will not blow off at 6 Bar or so - but we will see. Still quite some work... I´m just cleaning it and replace the gasket. Thats quite a piston and its in really like new condition (and I still have a spare piston)
