Constabulary

Just before I shot the Video my new 40mm pulleys have arrived (custom made and not from College Sewing) and I have installed them. So the new motor pulleys are 40mm, the pulleys at the speed reducer are 50mm and 150mm and the balance / fly wheel is 150mm as well. So it goes from 40mm to 150mm and from 50mm to 150mm. I´m very please with the performance so far, I only have problems with the old resin coated Army nylon webbing as it it extremely stiff and dense because of the resin coating. Seems I need a leather point needle instead of a round point but thats a different story. Regarding the new laws - wow - that is something I would have expected in the "bureaucratic" Germany but not in France My speed reducers are custom made so I have someone on hand who mills the pulleys out of aluminum. The reducer pulleys have 2 ball bearings so they are really nice and of a fine quality! When I ordered them I had no clue what the actual effects will be so I ordered them with 3 steps but 2 steps (50mm / 150m) enough so no need for the middle pulley. I´m still learning... ;-)

Just wanted to give you an idea of how it looks when my Jack motor is running at 200 rpm and how slow the needles goes up and down. Event an 500 and 1200 rpm it is still relatively slow stitching. So the more reduction you have the faster you can run the motor and the more punch you have at your needle at a slow speed. I´m not a technician and I cannot calculate the speed reduction from motor to balance wheel or the "belt distance reduction" in meters per second (or so) correctly but it is extremely slow and it works well. Quite sunny today - sorry about the light conditions but I think you can see what I mean. I hope this helps.

I use mine rarely. it is more or less a dust catcher (I maybe use it once or twice a month) as it really has it´s limitations. The only reason I have it is the 360° head and long thin arm. You can sew (repair) spots inside bags and pouches you cannot sew with other machines. I use 138 (20 metric) thread with my 29K71 w/o problems (it may take thicker thread but have not tried yet) but due to the tiny bobbin there is not much thread on it. Anyway - a nice to have machine but I would not pay big $ to get one. I would not buy a used one w/o knowing how long the stitches are (Wiz explained it). But it depends on how much a seller asks for the machine. I bought mine for just 40€ (unrestored) but I had to spent ~150€ + to replace parts and to restore. I did not know how long the stitches are until I had restored it but is makes 4.5mm stitches which is very good for a used patcher. It now is a really nice and functional machine for the money. But I think these patchers are far away from being a comfortable sewing machine for producing a commercial grade products. Juts my 2 cents.

Sounds good. Maybe I´m just to dumb - you never know

@VanRhodes I´m no scientist or electric engineer. All I can say is that it worked w/o the speed reducer and is not working after I added the speed reducer. That is m experience so far. I would make a video with and without the reducer but the belt cannot reach the motor pulley. I bought the 750Watts motor with NPS and the 550Watts w/o NPS. I will try if the NPS works with the 550Watts motor when I´m puzzling on my setup next time but that may take a few weeks.

It all depends on the ration between motor pulley and balance wheel. The smaller the motor pulley and the larger the balance wheel the slower the machine sews. 500rpm is the lowest top speed setting - meaning the motor makes max 500 RPM when you push the pedal down fully. The motor runs actually at 200rpm (slowest possible speed) regarding the display. When you add a speed reducer it will be much slower. I have added on both machines a 1:3 speed reducer and my Singer 133K sews much slower at 200rpm (motor rpm) than the Singer 111 as the 133K has a much larger balance wheel. I just have ordered custom made 40mm pulley to get a more torque.

Here is the thread: http://leatherworker.net/forum/index.php?showtopic=56955&p=365941 @VanRhodes Maybe it is different with your machine as far as I remember you have a fixed gear reduction mounted on your machine so there is no belt slippage... but I don´t know for sure. Just a guess.

I think TROX or someone else explained in in an other thread, it is because of the belt slippage as far as I remember. I don´t know for sure if other sewing machines / other servos with NPS wok with speed reducers but my experience is that the Jack Servos do not! I´ll try to find the thread... When I look at the Cobra 4 and Cowboy 4500 it seems these machines also come w/o an NPS and both have speed reducers so I don´t know. I think it is a general issue when you are using speed reducers but I´m not sure...

I had this one but with 400 watts http://www.ebay.de/itm/SERVO-MOTOR-mit-Nadelpositionierung-ZYT-250-W-/350886574903?pt=DE_Elektronik_Computer_Haushaltsger%C3%A4te_N%C3%A4hmaschinen_PM&hash=item51b2783b37 it made an unbelievable annoying "beeeeeeeeeeeeeeeeeeep" sound when it was running and the needle positioning system did not work properly (even without speed reducer) Not sure if they have updated the new models but I would not buy it again. The other one was unbranded and I don´t recall the model and I no longer see them for sell so I cannot provide a model name or a link. But it came from SEWTEX in Germany. It was a pain to deal with them - I finally got my money back from Paypal. The rest is history! I´m very very please with the Jack Servos and I recently have bought a 2nd motor. But if you have or need a speed reducer on your machine then the needles positioning system of the Jack servos will not work. But I figured I don´t need the NPS at slow speed as I can see where the needle will stop. So I ordered the 2nd motor w/o needle positioning system.

I can highly recommend Jack Servo Motors with 750 Watts Motor from College Sewing - this one is quite powerful and it runs on 220V and since Great Britain is in the EU you don´t have to pay import taxes and shipping is cheaper as well. https://www.college-sewing.co.uk/JK-561A-220V-750W=1HP-SERVO-MOTOR I personally have this motor with 550 and 750 watts and I´m very pleased with them. In case you need more torque you probably have to add a speed reducer as well - College Sewing don`t have them but they are fairly easy to make. Since your machine was treadle powered you already have a "hole" for the speed reducer shaft in the right cast iron table leg... I have added two picture of my setups with these motors (both have a speed reducer) so you have an idea. EDIT: Sorry - Norway is not an EU member but anyway - the Jack motors are great and shipping is still cheaper I think.

Well, I don´t have the time to translate the entire manual - I´m sorry. If it had contained one page (or so) with information you really needed I would have translated it but the main information are the same you can get from Singer 29K or Adler 30 manuals as well. But I have to admit that this is the most detailed patcher manuals I have ever seen! It even explaines that you can shift the needle slightly sideways by loosening the needle holder screw. - pretty interesting. I have not noticed this information in other patcher manuals. Thats what I said before - it is for darning! Thats something nice I´d say, I could use a darning device on my 29K71too and I hope I can make one But now that I see the video - I think I don´t need a special darning device. When I lift my foot lever it stays in this position... will try if it works for darning.... EDIT: no - darning is not working at my 29K71 with just a lifted foot. So its probably something different.

I just have scanned my original Singer 133K8 to 133K10 and 133K17 manual so here it is. Direct download link: Singer 133K8, 133K9, 133K10 and 133K17 Manual

Got the manual but there is no information regarding the sliding thing - I´m sorry. I think it could be a darning device. But thats just a guess. Some of the Singer 29K had a (different) darning device too (Wizcraft has one). I think when you slide it in the upper position and then tighten the screw it will disable the feeding function of the presser foot. So you can move the material freely by hand. You know what I mean? I have converted your manual to a printer friendly version and I have dropped some unnecessary pages to reduce the file size. So here is the direct download link: Manual Claes RPX Patcher Sewing machine (German Language)

these may fit but ask the seller before you buy: http://www.sailrite.com/Zipper-Foot-Set-Left-for-Professional They seem to be quite expensive. I´d contact Toledo Sewing first - maybe they have something similar - Bob also answered your post (see above).

Click on the brown button "MORE REPLY OPTIONS" in the lower right corner the you have more option and can upload pictures.

Wow - Artisan can´t support you with a simple inner foot? What a "Great" Company! I think the machine takes the standard Singer 111 type foot, don´t they? Can you post a picture of the foot era of the machine?

click on his name and there you have a "send me a message" button on the right

shank is ~2.0 - 2.5mm. I have (metric) size 110 with ~2.1mm and 180 with ~ 2.2mm and 200 with ~2.5mm diameter. Length from top of shank to top of needle eye is 5.2cm

Some progress on the wooden treadle stand but still enough pink to sand down I think I will motorize it and take off the treadle mechanism but I´m not sure yet.

Welcome on board! Es gibt ja doch noch ein paar Deutsche hier

Maybe you can post some pictures of your work. I think some member might know what the problem is when they see what happend. Pictures are often telling more than 1000 words.

Seems to be an Adler 49 with wheel feed (subclass 2 or 4 I guess). Pretty much the same class as a Singer 18 nut technically advanced.

Is there really an oil that does not stain unprotected / untreaded leather? I dont´think so. I do not use any "special purpose oi" I use S-761 weapons oil for everything! Mountainbike chain, household, sewing machine, weapons... everything. My simple opinion: What lubricates + cleanes the MG3 and M249 machien guns or G36 and M16 rifles can´t be bad for sewing machines. This stuff has a low vicosity and is well penetrating and it has a good cleanig effect on old gummed sewing machiens (espeacially in tight bearing). I love my S-761!!!

not sure how much elektricity you need but how a bout solar panels?

Is this sliding piece probably a "Darning Device"? I have sent you a PM with my email. I`ll see what I can do. but don´t expect it within the next week. It may take some time
