Reduce the foot pressure and / or use a roller foot with smooth surface or rubber layer on the wheel Not sure if this one fits your machine https://www.ebay.com/itm/142979318355 Not sure how your machine is set up machine but this would be an adapter for the above roller https://www.ebay.com/itm/145397360986 If your machine is set up with the flip aside roller foot already then there is also an optional adapter for using plain industrial presser feet (f.I. with a Teflon sole) instead of the roller foot https://www.ebay.com/itm/143603134209 with installed foot: https://www.ebay.com/itm/165883555629 If you have a 1 row needle plate and feed dog then this set could be helpful when using plain industrial feet: https://www.ebay.com/itm/143603162021

Seller here says its for the 47w as well (see description) - not sure if the belt for the 47w66 it different but I don´t think it is (not sure though). https://www.ebay.de/itm/122465742879 I just checked the parts list and googled the number. This is the old style belt with metal braces - above belt is the new type made of rubber / neoprene. https://www.ronsew.com/arm-shaft-connecting-belt-235003-for-singer-153w100-singer-153w101-singer-153k101/ However - compare the measures and number of braces and / or check with the sellers.

I have a revolving bush for this machine and other parts as well. I´m in Germany so shipping is not a problem.

I´m sure they are. I would guess the gears are probably old stock (or even old stock aftermarket). You don´t see many 110w's anymore and they have been discontinued for decades. I´m not sure but I don´t think anyone (even the Chinese) do not produce these gears anymore. Ebay is an underestimated source for old sewing machine parts and other old stock parts sometimes.

Ebay: https://www.ebay.com/sch/i.html?_from=R40&_nkw=DRIVNG+singer+110w&_sacat=0 Keep in mind, the stitch length for the 110 was never really long. Do not expect that there was a gear for 5 SPI or so. IIRC then longest stitch was 12 SPI.

@MrHydez If the shaft diameter on your machine is 1/2" then a Singer 111 hand wheel probably could fit. Maybe you need some spacers to align it with the motor pulley (maybe not). https://www.bmfwholesale.com/product/hand-wheel-singer-number-240545/

it can sew heavier - however test it before you buy it.

Do a forum search the Singer 78 and equivalent Consew 28 have been discussed here already: https://www.google.com/search?client=firefox-b-d&q=singer+78+site%3Aleatherworker.net Nice machine (I owned one. Bought just because I was curious but no longer have it) Not many parts are available for this machine so make sure it is complete and it sews. Compare pictures of other machines and make sure its all there. Needle is 135x17 / 135x16. As Alzilla said, you for sure want a different motor and / or a speed reducer. I have a few files: Singer 78 Beschreibung.pdf Singer_78_CONSEW_28_MANUAL.pdf Singer 78.pdf

Or just oil it manually. Don´t expect that there is a video or website for every single sewing machine.

Regarding needle bar - I guess its the same as on my 368 so pull off the top lid, loosen the screw of the face plate (comes form the top side) and bring the needle in bar in the lower position and then you can see the needle bar clamping screw.

BTW - the OEM Pfaff bulb is 62mm long and has a 22mm diameter just to give you an idea. Smaller bulbs may fit as well but I have installed a LED bulbs in my Pfaff 368 and it has a small diameter (16.5mm dia. and 56mm long) and it was a little bit fiddly to install them (grab, push & twist) because of the smaller diameter but it worked. The OEM bulbs on my side of the pond usually were 12V but they come in 220/230V and 110V as well so depends on what your voltage is.

You need bulbs with B15D sockets. At least the Pfaff I know used them. There are also LED bulbs with this socket.

This is what I have. Knob is metal no chicom plastic. 2nd pic is from a 138 parts list. Looks like I have 1 washer extra.

I have a complete lever w. knob and all parts for the 138. Not sure if is is 1:1 with the 238. Can post a picture later

Since the subclass is a rather low number the 29K15 is a very early model and most likely very identical to the 29K4 / 29-4 and similar early 29 / 29K machines. The difference often is just some different accessory and most likely there is no major mechanical difference. Often the accessories that make a difference are gone / got lost over the years so the basic machine often is the very same as more common 29K subclasses with just a different tag on it. Please post some pictures of your machine so maybe we can see some differences to other 29 / 29K machines.

well, check with the manufacturer and ask where to buy. https://globalsew.com/strobel/ or https://globalsew.com/strobel/

The teeth are important for feeding the material so thats normal and in the nature of this machine. Some folks but shrink tube on the foot but as you can imagine this can cause issues with feeding the material.

The needle system for the 45K´s is 328 or 214x2. There are several different leather needle tips available depending on what seam appearance you want to achieve. You can download a Groz Becket brochure here. They have a YT video as well: https://www.youtube.com/watch?v=w8HqAFtSPFg I run a Singer 45D91 (German made version of your machine but with reverse) and I´m using it for needle size 160 (metric) up to 230 (metric).

I think so but I only can guess - I assume the Bell Crank Lever is worn down or broke. See parts diagram in the above linked manual / parts list. https://www.college-sewing.co.uk/82167-feed-motion-bell-crank-lever-singer-29k412818.html OR - there is an issue with the lifting lever. https://www.college-sewing.co.uk/82152-lifting-lever-for-heavy-work-singer-29k.html-` I'm not sure If I can see it from the rear side. The lever should stick out here (arrow 1) and should lift the part (arrow 2) when cranking the machine. Should look like in the 2nd picture (my 29K71 machine).

I have edited my last above post. clockwise is correct - the plunger engages / disengages the hand wheel when winding the bobbin. BTW - here is a parts list and manual for the 29K71 - it is very similar to the 29K58 with just some minor differences. Hope this helps. (direct download link) https://leatherworker.net/forum/applications/core/interface/file/attachment.php?id=172617 ======== EDIT: Here is missing a thumb screw. Should be this one: https://www.college-sewing.co.uk/ss469w-eccentric-thumb-screw-singer-29k.html

this plunger knob is missing on the hand wheel of your machine https://www.college-sewing.co.uk/nn98r-plunger-nut-singer-29k.html I´m also not sure if the paddle shaped spring on the lower end of the needle bar is present - please check that. https://www.college-sewing.co.uk/46045-8656-check-spring-singer-29k.html Above two parts have nothing to do with foot movement but both needed when you want a properly working machine. You have not posted a picture of the rear side of the machine and have not answered in which direction you turn the hand wheel. Just trying to figure issues before you start removing parts. ====================== The 180° rotation of the pulley usually is an issue when some one restored / took apart a machine and did not put it back together properly. Yes IF the pulley is the issue it is the one you mentioned. It usually is held in place by 2 set screws and 1 tapered pin so you have to figure which side is the narrower end and hammer it out from this end. It sometimes is hard to tell so be careful if you hammer it from the wrong side it will be even tighter. However there is also a cam inside the machine that drives the hook (basically) and one on the left side that controls the feed motion ring. So IF someone restored it / took it appart no one know if he put back on the cams the right way. So there is a lot of guessing.

Please note the above post. The gib and the frame have wedges. This is how the stitch length adjuster and the gib should be installed.

hard to tell from the videos what is going on. But I wonder why the bell crank lever is seemingly not properly moving. I only can guess as I´m not in front of the machine. Could be that the bell crank lever that is moving the foot is worn or broke. https://www.college-sewing.co.uk/82167-feed-motion-bell-crank-lever-singer-29k412818.html it is playing together with the feed motion ring. https://www.college-sewing.co.uk/82053-feed-motion-ring-slide-bar-singer-29k.html When the FMR is mowing up and down the BCL is moving the presser foot bar > feeding the material. But again please post good clear pictures of your machine so we can see is something probably is out of alignment or missing and straighten the foot pressure adjuster. EDIT: What I also noticed is that the stitch length adjuster is not correctly installed. The arrow on the small squared frame has to point upwards and the gib has to be positioned correctly as well (I´l post pictures later)

Looks like a 29K71 or which one is it? The presser foot looks kinda odd. Has it teeth on the bottom side? The foot pressure adjuster looks bent (see red arrow in picture). Furthermore looks like the stitch length adjuster is set to a short stitch. In which direction do you turn the hand wheel? Have you read the manual? Please post good clear pictures of your machine from front and back. EDIT: you mentioned the bent adjuster already - sry. But put everything back in working order before you start adjusting / removing / repositioning other things like cams and so on.

Make sure the timing belt is in good condition, the old brown one soften became brittle with the time and replacing them is a little bit a challenge but doable.
