Constabulary

Does not surprise me - with a thin needle and thin thread almost every sewing machine can do that with 3mm leather - thats physics. Guess why the doctors are using thin needles on syringes

Mad electric scientists!

Glen - so sooner or later we can read a japanning 1O1 here, right? It´s indeed an interesting process I´d like to read more about. Where have you sourced the "paint"? Jimi - have I ever mentioned that I hate you for your nice 45K´s?

don´t know the machine but when a valve with a threaded cap is leaking through it´s threading I´d try some loctite or JB weld. At least worth a try when its it shot anyway.

I don´t know what sort of patcher machine that is but it is not a Singer 29K60. I GUESS it is one of these rough Chinese patchers, right? Like this one - see linked thread? If it is the above check with LW Member Darren Brosowski he is selling them.

@ Lumpendoodle - A very nice machine you have!!!! I have some pic of a pre 1945 Singer 45Dxx (not mine) - still very shiny

Thanks Glenn. You always learn something new everyday - I did not expect they switched to metric measures - good to know. With other words - better leave em alone when you find one that (may) needs parts?

GOOD LORD - what a nice bunch of machines. Can I add a Needle Positioning System and has JUKI ever built s clone of them

I´m pretty sure they are since all later 29K´s with replaceable gearbox have a lot in common. I only noticed Singer returned to the simpler and cheaper to produce thread take up lever adjuster at one time but I´m sure most if not all other parts are interchangeable. But to be 100% sure you should compare the spare parts list oft he 29k73 and 29U173U when you are looking for a specific part. Will try to add the files I have for the 29K72 / 29U73A EDIT: I also have a 29K73 PDF parts list + manual but cannot upload and and cannot compress it to a readable size. Send me a PM if you want it 29U171A_172A_173A.pdf Singer 29K - 29U171A_172A_173A.pdf

will try to save that information - thanks Glenn

Maybe the CB3200 from Toledo Sewing is an option - it´s also a walking foot machine and cost way less http://www.tolindsewmach.com/cb3200.html

Just from looking at your picture.... Look for Juki 415 or 555 - they are pretty much the same class - maybe a little bit bit different. I would even guess this one is probably a bit an earlier model.

Forgot to add Nakajima

Mitsubishi - Juki - Seiko - all the same

I think I have seen a Mitsubishi machine that looked the same but I don´t recall the model. However the Techsew 2750 looks similar to it but the Nakajima has no walking foot. http://www.techsew.com/techsew-2750-cylinder-walking-foot-industrial-sewing-machine.html/

You are welcome - hope your problem is solved.

You can download a Pfaff 238 manual here - 238 is the same as the 234 but the 238 has zigzag - threading is the same: https://www.google.de/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwipwN6l1MjQAhWBLsAKHflsDswQFggiMAA&url=http%3A%2F%2Fwww.supsew.com%2Fdownload%2FPfaff%2FPfaff%20238%2C%20238-0%20Instruction%20%26%20Service%20Manual.pdf&usg=AFQjCNH1Y4jfNiAfzWWpHecKAYVXU-3Zxg&bvm=bv.139782543,d.ZGg

The bearing screw just holds the shuttle driving lever, there is no eccentric on it for adjusting the timing. The screw has to be tighten. My guess was that the cam pulley at the right end of the machine which drives the arm up and down needs a 180° rotation. May I ask if you have taken apart the machine for cleaning and probably have reassembled some parts (cams and / or gearbox) incorrectly? There are 3 cams on the main shaft and they all have to be in correct position otherwise the machine does not work. The small cam on the left side (feed motion cam wheel) is usually has a mark that needs to align with the mark on the shaft. The other 2 do not have marks but they have tapered pins which usually just fit from one side and you usually can see the "foot prints" of the set screw on the shaft. Still a guess form the distance I don´t claim that I´m right with this but I still think the cam pulley needs a 180° rotation. So I would drive out the pin (remember - its tapered), loosen the set screw and turn the pulley by 180° and test again. Pulley might be tight on the shaft so you probably need a gear puller and clean the shaft and inside of the pulley with some 320 grit sand paper before you reassemble it. EDIT: This is needle up and needle down at my machine - notice the position of the shuttle carrier - it´s just the opposite as on your machine so I´m sure your cam pulley needs the mentioned 180° rotation.

Not sure but I´ts possible. On external clutch systems like this I have seen leather as well as some very hard dense stuff same as used in some clutch motors. I know some clutch motor had asbestos fibers in their clutch plates. I think LW Member EVO160 once replaced a clutch plate on a similar system like yours with some hard sole leather if i remember correctly.

MoMatt - a lot of the early 29 / 29K models do not have the timing eccentric. Not sure when (or what year) they have introduced it but in this case I doubt it has the eccentric but I´m not 100% sure. I once restored a 29K1 from 1905 and it also had none. So its quite possible that this one from 1902 also has none. @DeiDragon Don´t know if you have removed the cam pulley before if you did you surely know the pin thats holds the pulley on the shaft is conical / tapered so you can drive it out only in one direction, otherwise you can probably damage something.

What you wanna know? Its a made in Japan 29K machine similar to the 29K73 small bobbin long arm patcher machines

Since the needle hook timing is way off as it seems problem could be a wrong assembled gear box or the driving cam pulley at the right side of the machine is in a wrong position. From just looking at you picture I would GUESS the driving cam pulley needs a 180° rotation.That would me my diagnosis from a distances.

right - haven´t noticed the stitch length so 138 thread does not make sense! Sorry!

if it is not too expensive - why not - I would make the trip and test it. I also have machines (just the heads) that I'm barely using. So what - they don´t eat bread and just need some oiling from time to time

I guess it has the same hook as the 153 though I´m not sure. In case it has the same hook it most likely can handle 138. So I would go and test sew the machine. The seller should not have a problem with that. Needle system is 128x3 so a 22 needle should suit the 138 thread.
