Members 29k15engine Posted June 25, 2021 Members Report Posted June 25, 2021 Hello all, I have bought and fully restored a 29k15, the fact is there are alot of these marques out there so it seems a shame that they can turn into large paperweights due to the fact that the shuttle gears and rack are unavailable. Im looking into what would be required to make all three gears and rack. If i could get the original gear and rack engineering drawings it would be hugely beneficial however i think these are no longer in existence. The good thing is that mine has light wear plus the end of the rack gear is virtually profle untouched and a good candidate for profilling the shape to make a hob for gear cutting. Here is my 29m after i restored it ,paint ,decals ,new pulley ,follower and a lever spring made by myself from 01 grade steel and then heat treated to make a spring, i also made the foot height adjuster. Any help on info would be appreciated Quote
Members jimi Posted June 25, 2021 Members Report Posted June 25, 2021 Hi There, Well done on your restoration job, It looks really good and the decals also look nice. I do not think you will find any drawings of the pinions from Singer but maybe someone has made a drawing up at some time because this is the eternal problem with the old 29k machines, the gears and rack wear down and people by new parts from the internet advertised for these machines but they are really only for the newer models 29k71,171 etc. There is someone on Ebay selling the leading pinion for these older models but you never see the long racks new for sale, only for the newer 29k71 types.

CowboyBob Posted June 25, 2021 Report Posted June 25, 2021 Nice looking machine you have there. The problem with these older models w/o the steel ends is the casting where the rack slides against can get a groove worn in it that requires brass to be welded to the backside of it as a shim to get the gear closer to the pinions.I'm certain this is why they re-engineered & adapted the replaceable ends on all of the newer models.We have also seen where the hole where the shuttle rides in enlarges to a point it is so loose that it won't sew correctly either.We use .950 as the limit & anything beyond that we strip them for parts.

Members 29k15engine Posted June 25, 2021 Author Members Report Posted June 25, 2021 Many thanks Cowboybob and Jimi. Its my first machine, before this I made a leather jacket from scratch with a handheld speedy stitcher so its luxury having stitches mechanised. I can see that the rack can wear the back of the cast casing, wonder if a new slightly thicker rack would be an option here, then it could be honed to fit (Most new parts now need honeing, e.g the new pulley cam I bought took a whole evening to fit, at first the follower would not even go into the cam groove) As my 29k had been painted when I bought it a horrible blue I carefully sanded it with a motorised finger file right back to the casting, then used some black etch primer, 2k auto paint brushed on and hand sanded, then sprayed 2k laquer followed by decals and then the same ammount of laquer. The machine came with the correct treadle table which I am now restoring. It stitches 6 to an inch. As a side not I have found a "possible" stock of shuttle gears 8608, i have ordered 2, Im not sure if they are new old stock or just good old ones but took a punt at 10 euros each. As 2 is all I need here is the supplier. http://sitomaco.es/product_info.php/products_id/4445 below is my first leather jacket, as said made by hand with a speedy stitcher. Just to say Cowboybob your machines are impressive. Mat Quote
Members 29k15engine Posted June 25, 2021 Author Members Report Posted June 25, 2021 The 29k15 was £40 in a junk shop so im pretty happy, the jacket however is too heavy for everyday used so Im on the lookout for some nice leather under .9mm maybe nubuck or nappa, I enjoy the challenge. I have had a play with the 29k and made my wife a leather bucket bag (she wanted brown leather so an early present for my mum) it didnt miss a stitch so im happy. The copper rings are made from copper brake pipe wrapped round a pipe, then cut and formed into a ring. Hope you like, now back to gears and racks..:) Quote
Members 29k15engine Posted June 25, 2021 Author Members Report Posted June 25, 2021 (edited) Im now thinking maybe I have fallen into the trap of ordering the wrong shuttle gears.... I have always gone on the part numbers in the singer29k2.pdg here https://www.college-sewing.co.uk/wp/wp-content/partsbooks/Singer/Singer 29K2.pdf which shows the 29k15 as using 8608 following pinions this topic https://leatherworker.net/forum/topic/88993-singer-29k70-gearbox-inspectionShows 3 gears which do not look like mine, the 4th picture shows what my gears look like. So the question, what is the part number for my gears? is it 8608 if that is correct has my supplier put the wrong picture up here. http://sitomaco.es/product_info.php/products_id/4445 any help would be appreciated, especially if you speak spanish as i do not.

Members 29k15engine Posted June 26, 2021 Author Members Report Posted June 26, 2021 (edited) Thanks for the kind words on the jacket. I do have the pattern for the jacket somewhere. The way i did the pattern was to pattern another jacket i had, panel edge to panel edge then add the seam needed depending on what the seam was e.g full felled seam. I made a mock up of the jacket in automotive fabric i had around as it had a scrim back which had depth to it to try out the seams. As said the leather is heavy making the jacket too heavy for day to day use, the way i look at it is if you can make a heavy jacket and work out all the folded seams, then a thinner one will be alot easier. The thicker the jacket the more the fit plays its role, i know very little about tailoring but would say the most important area to get right is how it sits on the top of the shoulder and around the neck, the thicker the leather the more this area matters. Also with the seams skiving and hammering the leather is needed to get up to 5 thicknesses to lay right. Lessons i would pass on to my next jacket. 1. Choose the leather carefully, go thinner rather than thick 0.8mm initially ( look at how the leather reacts when its folded and doubled up as some seams may require this) 2. Make a full mock up of the jacket in a cheap appropriatley thick fabric with ample seams to get the fit right around the neck, shoulders and arms 3. Under the arms should go up to the armpit, the higher this area is tailored the better the jacket will move and thus not lift the jacket when you put your arms in the air. However give the whole area more than ample space to move in inside the sleeve plus lining. 4. Wear the mock up and move around, move your arms to get an idea of where the arm needs more space when articulated. 5. Learn and practice full felled and half felled seams until you are happy with the results 6.use basting double sided tape 6mm to join the seams ready for sewing, the sewing should be the last finishing process to lock all your work up to that point. Most basting tape can be removed after sewing, try to attach the basting tape to hold the seam but not under where the stitch is if at all possible( gums up the needle) 7. Practice where the arm joins the body of the jacket, the arm hole needs to match the jacket arm circumference perfectly, enough seams on both body and sleeve which must match as this is sewn inside out. 8 where the end of the shoulder joins the jacket is a critical area which sets up how the jacket arm will hang, its also an area which needs some strengthening on the inside as the arms will try to pull from here when they hang. Hope this helps someone. Remember your first jacket may not be perfect, but what you will learn is priceless Edited June 26, 2021 by 29k15engine Spe Quote
Members 29k15engine Posted June 26, 2021 Author Members Report Posted June 26, 2021 Note the lining is hard to learn until you realise you are duplicating the jacket just in material, then with a few tweaks you can get it to sit flat inside, note sleeve lining benefits from more rather than less space to move your arm Quote
