you definitely should! Better asks for good detailed pictures from all sides - race parts are rather easy but other parts are way more difficult to find! EDIT: BTW - I just noticed the race parts seem to be present - see red circle!! Anyway - ask for more detailed pictures of the whole machine!!!

But this does not slow down the motor it still starts at 500RPM min. In the accelerator unit you can move the small black lever a bit to the left or right to get more or less "play" in the foot pedal. Its a bit trial and error. Not sure if your look the same but I guess it does.

I may have some used OEM Singer race parts but have to check.... Please post pictures of the shuttle race area so we can see what is missing.

Will you share the information you have or...

There are different type of needle feed machines feet out there - The Singer 111 type needle feed feet are different - I guess Eric (Gottaknow) meant the 111 type machines / feet. These feet fit on slotted foot bars only. https://www.college-sewing.co.uk/store/Singer-111W-and 211G-Needle-Feed-Feet

wow min. 500 rpm is quite a lot - my servos start at 200 rpm but they are made by JACK (or labeled JACK). and I run them with a 3:1 pulley speed reducer. I´m not electronic guy and I´m not sure if an additional electronic speed limiter would work at all in combination with a servo motor. However I once added a quite simple speed controller to my electric bobbin winders - but not sure if this works in combination with a servo motor. I think a pulley speed reducer would be the better idea as it even increases the torque. You probably have seen this video already on YT:

That was my thought too - I would guess a barrel hook machine (CB 2500, CB3200, Singer 45K, Adler 5, Adler 105 and the like) would be easier to clean / maintain around the hook and feed dog.

Impressive - seems it did not hurt the machine. But who knows how much mileage other machine have which do do not have a stitch counter. Maybe the Allied used this CR stitcher for decoding the German Enigma machine *kidding*

Seems to be a 132U - the made in Japan version of the 132K - seems to be plain drop feed (no jump foot) machine as far as I can tell from the pictures. Good long lasting and reliable machine but it ha no reverse. The bobbins are HUGE and hold lot of thread. Lots of spare parts are still available from College Sewing in the UK. Check this thread for a Singer 132K6 / Seiko SK-8 Manual

THAT is a really cool idea - I REALLY LOVE the Singer key fobs

its form the 29K71 - 72 - 73 manual 29k71-71-73 Service Manual and Parts List.pdf

Agree - Adler 30-7 can sew a bit thicker approx 2mm more than the 29K72 /29K172 But if a patcher machine is a good patcher machine always depend on it´s overall condition - if worn out you will not have much fun with them. If they are in good condition both (Adler and Singer) do a good job - if you put them into the right job Keep in mind patchers are sewing machines mainly for repairing things!

Singer 107wxx / 143Wxx I would guess but don´t ask me for the subclass - cant you ID the oval small brass tag?

you probably have to push the material a bit into the binder attachment - especially in corners. When the binding tape moves out of place I would guess the binding attachment does not match the width of the binding tape. Cork fabric sounds interesting - have to google that!

oh men - I live on the wrong side of the pond...

Original file came from LW member qvt to be fair

A 29-4 is a very very very old machine - it was designed for repair work like patching shoes and boots or sewing rather short seam, sewing in tight spaces and the like. Thats why the bobbin is small. There are also 29K´s with larger bobbins like the 29K31, 29K60 or 29K72. But these machines were not designed for producing leather items though many folks are using the machine for this work - plain and simple these are machine s for repairing things. It could well be that your machine is worn out and you have to replace some parts but not many parts for the 29-4 are available. The "up to date" version of you 29-4 is the 29K71 and you get almost very single part for it but yours is many decades old. You probably have missed this thread:

if you need a good user manual check with LW Member qvt - I posted his PDF sized reduced here but his original file really is much better.

The tension unit on top for the bobbin winder is a quite cheap part you don´t need original Adler part here. I put one of these on top of by BUSMC #6 bobbin winder https://www.college-sewing.co.uk/store/SB3571-1-01-BOBBIN-WINDER-TENSION-ASSY-BROTHER College sewing could be a good spare parts source for you anyway. Hope this help with your hook.

... and if there is no pinion on the top shaft you need that one too but that means disassembling the whole machine and pulling the top shaft.

I already can tell from the pictures that this is NOT a 29K60 - it spears to be a large look machine (like the 29K60) but this definitive is an earlier model. I still bet its a 29K31. The original 29K60 is a large hook machine with removable gear box / horn, it has a helical presser foot spring and NOT the blade spring on the backside of the machine. It pretty much looks like the later 29K72 but with minor differences (thread regulator f.i.) because of cheating customers - probably for "claiming" that this is a more modern model. I don´t say that the last owner did this but seems some one did it. But his plate does not look like a Singer plate at all - it spears to be too high and as mentioned the But you never know... This is how the 29K60 should look like (treadle base is from short arm patcher) http://horsenharness.com/SINGERMACHINEFORSALE.html

To me the 29K60 plate does not really look like an original Singer plate. Would you please post pictures of the whole machine - especially the head from front and back and the hook with open needle plate and hook insert. I`m not sure it maybe the machine has a wrong tag and it is not a 29K60 - maybe it´s a 29K31

Can you post pictures please. Is the busing for side wheel mount present and when you look at the cam inside the machine (top shaft) do you see a pinion mounted on the cam facing right (when you look from the backside through the hole behind the cover plate)?

That was not meant offensive - I just wondered if you want to use it for leather work. You for sure find chain stitches in leather work (on shoes and leather handles f.i.. - Puritan machines are chain stitch machines too) I´m the last who don´t understand if someone wants to keep old cast iron alive I also have a Singer 25-56 chain stitch on my restoration shelf. I already know I have no use for it but I´m just interested in how it works so I followed your work a bit though the 25-56 is totally different.
