@ dirkba What parts are you looking for? Usually the 111w / 112w parts are quite easy to find and most parts do not cost much money. @ Evo Can you post some pictures of the upper feed mechanism? I have worked on Adler 5 + 105 with the top feed / flip back foot and on an Adler 4-23 with driven upper feed (I hate my self that I have sold this machine) so maybe I can see some similarities.

I don´t think so but who knows - patchers often came relabeled for other dealers. maybe this thread is interesting for you: http://leatherworker.net/forum/index.php?showtopic=61501&hl=steriods

Here you can download one in German language http://altenaehmaschine.de/WebRoot/Store21/Shops/2e417a17-bb16-4da8-a113-3b6ba273bc8a/MediaGallery/Claes_Elastik_I_u_III.pdf

srry - I was on the wrong track - when top thread pop out of the tension discs you have loops on the botton not on top (top tension lost bottom tension higher in relation). Well thats the only explanation I have. Please post a pictures of your tension unit. The angle of the thread really matters - no joke.

Just a guess but if that is on top I´d say thread popped out of the tension discs. You probably have to alter the angle the thread goes through the tensions discs. The thread guide is a bit odd on the 211 (at least the few I have seen) - you have to put the thread guide in an correct angle. Sometimes the angle is not flat enough. Post a picture of your tension unit please.

This is the clamp I have it´s original Singer and came with my 133K3 If you are interested please send me a PM

Sewing machine dealers should hire you for producing proper Videos - once again very well done!!! What binder attachment are you using are they from Knowhing (or so)?

Yes, it´s a sack darning or bag closing machine you cannot sew leather goods with this machine. Anyway, I have a PDF 133K8 sewing machine manual I could send you when you send me your email address by PM file is too big to attach.

The oil "bottle" hanging form the oil pan usually collects excess oil AFAIK. some machines have an oil reservoir in the hook saddle meaning the hook gears or hook shaft are running in an oil bath / reservoir and often some wicks are coming from this oil bath and lead to certain oil spots. Post a picture of the underside of your machine that may be helpful.

Seems I missed this thread - sorry the links are dead. I will look if I still have the PDF´s on my PC. Raymond, can you post some pictures of the 133K4 please - I never heard of this subclass.

Learn it it will not hurt you. I had to learn English too. It´s not perfect but I survived 2 weeks in the USA.

I´m sure I have a clamp but not the one for the ball, I have one that clamps the arm the cable goes through - I will look for it tomorrow. You also can replace the bulb with and LED bulb - I did that on my Singer lamps as well - works fine - nice bright light.

What kind of help do you need? You ca buy a manual here: http://www.sewingpartsonline.com/instruction-manual-white-768.aspx I think you probably need another machine - this is an odd domestic garment sewing machine with a way out dated vibrating shuttle bobbin mechanism. This is not a machine for serious leather work. You should read this pinned thread here: http://leatherworker.net/forum/index.php?showtopic=25239

@ teched if you don´t mind can you make a PDF file from your original manual and parts list? Documentation for these machines are available but quality is quite poor most of the time. I think a lot of folks would be really grateful. My 111G156 has a W prefix serial number so the housing was made in Bridgeport but machine was assembled in Karlsruhe, Germany. The badge on your machine makes it a 1960´s made machine though AFAIK the 211 predecessor were made in the 1950´s already. With some luck I can pick up a 212 (double needle) tomorrow and if I´m right it has a 1950´s type Singer badge. So Uwe´s theory could be correct I think.

Your machine is a dedicated binder machine so short stitches are not too unusual. I would say maybe it is the mentioned plate - I´d probably remove it and see if the stitches become longer when you hand crank the machine w/o the plate. Also check your needle plate - maybe you will need one with a longer slot when you increase the stitch length. You know what I mean? I have two list of Pfaff 335 sub classes maybe you can compare the tag on your machine with them to find out more. 335 H3 Subclass Old C.pdf Pfaff 335 Subclass parts.pdf

When I look at the picture, then there is a plate #9626 - any chance that your plate has a shorter slot or small metal pieces behind it that probably cuts the movement of the adjuster knob? I remember I have seen this modification on a Dürkopp 239 machine. I removed it and viola longer stitches! BTW - alway helpful when you post pictures.

Don´t know but I have a picture form a very old 145 parts list and maybe it can give you some hints. The adjuster mechanism should be the same

Are you holding back the thread when you start sewing? You may need to adjust the bobbin case opener. Lower thread coming of the bobbin from the left? Not correctly threaded? Thread braking may have several reasons...

How about keystone Sewing Machine Co. http://store.keysew.com/brands/consew

Don´t know - maybe because he can!

Holy smokes - what a nice machine, too bad you never restored it.

I´m curious... Have you heard of the guy who invented a rotary hook patcher based on the 29K? The Video and music are a pain in TA but maybe something for you as an Engineer:

Funny - the Chinese are able to produce "high class clones" but are not able to copy a simple patcher which has been around for more than 100 years. I´d rather buy a decades old Singer 29K and put $250 of parts in it before I buy any of these Chinese or far east patcher machines.

I have set my servos to 2700 rps max speed and the speed 3:1 (150mm : 50mm) reducer doest the rest. I´m using JACK Servo motors from College Sewing with 750Watts I have no problems all with the speed control. Both are brushless servos. Servos stop as well when you step off the pedal. The brush type motor have a mechanical brake and the brushless have a magnetic brake AFAIK.
