    Looking at diagnosing an old Singer 29k71 that will not sew.

  1. Thank you Ole South! That is a looooot less than what i spend on the other hook even with the conversion rate (Im in Canada). So i just purchased it. Still dont know if i can return the other one but i need a hook regardless. Andre
  2. All, thanks for all the great replies, Tried all of the above and i checked timing again. I think it was off. Still not working great so, for my own sanity, i took out the new hook and put in the old one and now its working as it should and not skipping. Full disclosure, i think i was sold the wrong hook. It fits but does not have a notch on the shaft so i had to eyeball it for timing and just slip it left or right to make it work. The shaft seems the same otherwise but has a weird reverse screw on the bottom and no notch, and the hook and basket also seems the same except for the hook gib has a hook on it where the old one dosent. I suspect its slipping a little because of the lack of a locating notch or i still had the timing wrong. The one i was sold is a Hirose HSH-12-15MTR and i was told it would fit my machine and was labelled to fit a Juki Lu563 but looking into it, it seems its meant for a MITSUBISHI LT2-230M,2230M. No reason why i could not make it work with the proper timing but i just cant seem to be able to time it correctly. I was told mine needed to be replaced because the basket is a little lose but the hook looked in good shape otherwise. Should i even replace it? I will return the new hook regardless as its a lot of money for something that only sort of works. As mentioned above, it should work ok at slow speed and all of my missed stitches were at slow speed. I have a servo motor set pretty low and still it was skipping with the new Hook. I could not make it skip if i turn it by hand. As for the sizing of the needle and thread, 125 is the smallest i had so i used them. I have 120's for leather and 130 and 140 for the big stuff. I tried multiple needles as i thought it was a bent needle as well and still issues with brand new needles. Lastly, when putting it back together, i faced some of the pieces with a stone especially the Dog surface as it was worn sideways a bit and it seems to fit better now. Sorry for all the questions. This is my first walking foot machine (Besides the 29K) and i am slowly but surely getting familiar with how they work. Seems they are really Picky with Thread tension and Timing ETC.. Andre
  3. Hi Northmount, Thanks for the reply, Using Tex 70 with a 125 needle. using soft leather and some rubbery material. Played with the presser foot tension as you suggested and still i have issues. Did a bunch of tests with different thread and for a bit it was working fine but again, it started skipping. Put leather in there and again and its even worst... It was working better than that a few days ago... could my timing be slipping? Andre
  4. Hi All, I recently purchased a well used Singer 111W155 locally. Came with an old singer table, GE motor and Singer Clutch. I transplanted it into a more modern table. It was sewing fine but seemed to be skipping stitches. So i went shopping for new parts. So far i replaced the Timing belt (Was not broken but seemed about to), Hook (The basket was loose), New Tension Disk set, new bobbins, new needles. I cleaned it and lubricated it, Timed it and it is still skipping stitches. I tried everything... new needles, different thread different material and feed speed and still no luck. It seems to work fine for a while then every once in a while, it skips a stitch, sometimes 2 or 3 then goes back to normal. This can happen consistently on test pieces with about 3 inches of stitch so its pretty bad. The machine is quite worn and the feed dogs and throat plate seems worn also. The foot is a narrow foot set and also seems to be worn. I suspect what is happening is that the hook is able to get the loop most of the time but due to the slop in the foot or dogs or throat plate, the needle deflects and its just enough to miss that loop. I keep playing with the hook adjustment to get it close to the needle scarf and it seems every time i look at it, its in a different position (Either too far or touching the needle). I thought about the worst, too much wear in the needle bar bushings or even worst a bent needle bar but im really thinking it needs new feet, a new throat plate and feed dog. Before i drive myself crazy and spend more money on parts, can anyone think of what i missed? Thank you!!!! Andre
  5. Thanks Wizcrafts! Yes you are right, that spring needs to be there and in good condition. Luckily, mine is still fine. Good tip about keeping the screws int he same spot! Andre
  6. Update to the topic, My dad came over last night, he also has a 29k71 and he gave me a few pointers that are quite useful. He also gave me a bunch of new 29-3 needles for it. Although they seem really basic, they were not obvious to me even after reading the manual: Problems sewing with one or the other hole in the throat plate could be due to the setting of the needle. needle could be installed slightly off centre, causing the loop not to catch. Also, you can adjust how close the needle gets to the shuttle by moving the second screw above the one that holds the needle ans adjust how close the needle gets to the shuttle when sewing. This makes for consistent stitches. This could also fix the problem of missed stitches. Also, needles could be too long, causing it to go too deep which could have been causing my prior issues. Looking at the needles i was using, they seemed slightly longer than the ones he gave me. I was of course using the needles that came with my machine. 1 was already installed and 2 were hidden in the oil cup. all were quite worn. Invest in needles before you invest in parts! Adjusting the take up lever on top of the arm could also help with making sure that enough thread is able to catch on the shuttle hook on the down stroke. this will also make sure that you get consistent stitches. All those are fine adjustments but can make the difference between a bad stitch and a really good stitch and could also solve issues. I also found that marking items off and eliminating problems one by one is a good way to find the root cause of your issues. Other things i have learned, and that i could not find the answer anywhere: Shuttle Carrier can have some slop in it without causing major issues. If you time the machine and find that you can move the shuttle carrier a little from side to side, that is normal. Too much slop would cause inconsistent stitches and misses stitches as the loop could be missed and timing would be flaky but some slop is ok. When sewing, the thread should be caught by the shuttle hook, brought over to catch the bobbin thread, pass between the shuttle/Bobbin and come back between the shuttle carrier and the shuttle through the tension spring to make a full stitch. It will not sew until that happens reliably. You can test this without using a bobbin or without having the throat plate installed. Timing does not have to be dead on for it to work. The manual says that on rest, the shuttle carrier should block the needle entry point at 1/3 but there is some give and take there. Refer to earlier point to test whether you can reliably get a good stitch. the throat plate, Shuttle, bobbin, shuttle carrier should be clean and free of burs and polished. I have used Autosol to polish my parts. Metal polish of any kind should really work. the smoother the parts, the better! Hope this can help someone get their machine working! Andre
  7. Good news! Success! I was able to get it to consistently sew! The problem was in fact the Shuttle Carrier. My machine came with lots of parts, including an extra bent shuttle carrier, i figured i had nothing to lose and i used a punch and various tools to bend it back into shape. I then cleaned, filed the burs and polished it with Autosol and success! it works perfectly!. I should mention, i had tried everything. My machine came with 2 extra rack boxes, one extra bearing, one extra short rack, 2 extra long racks, extra bottom plate, extra throat plate and assorted screws and hardware. None worked until i beat that old shuttle carrier into shape. Now, i really trying to understand whats different with the other 2 shuttle carriers, perhaps i can make them work too. perhaps they are ever so slightly deformed and are causing an issue. As for the throat plate, mine is really worn on one side and not on the other but using the non worn side makes it bind and the other worn one works perfectly. Weird. Andre
  8. Thanks again, Yep, i also purchased a cam wheel replacement as mine was broken and i had to modify it heavily to make it work. That included drilling the hole for the pin and widening the cam channel so that the bearing would actually fit in it. Never buying reproduction parts ever again thats for sure. Andre
  9. Thanks Jimi, I did look through this topic but i assume the replacement i got would do this. I guess the aftermarket parts are a waste of money. Andre
  10. Hi, I am new to the forum and have been reading around. Lots of great info here! I have recently inherited a Singer Patcher 29k71 that used to belong to my grand father who used to be a cobbler. He had lots of those, unfortunately, he ended up selling most of the old machines but fortunate for me, this one survived and was passed down to me. I was able to get it completely restored and repaired but i still cant get it to sew properly. I know the problem but i dont know how i can fix it. Problem is that it is timed properly but it constantly gets jammed because the thread ends up under the shuttle carrier. as such, i ordered a replacement shuttle carrier (not an original part) and installed it but i still have the same problem. I was able to get it to sew a few times but it ends up jamming in the end. What i noticed is that the bearing between the shuttle carrier and the driving pinion seems to stick up a little too much. As such the shuttle carrier is too high? Other thing i was thinking is that the hole on the shuttle carrier where you put the set screw is too low and when fastened on the driving pinion and there is too much play. Or the driving pinion is worn down and there is too much play. Either way, before i buy anything else, i could really use some help. Thanks! Andre
