Singer 29 stitch length adjustment

The Singer 29-4 models are going on a hundred years old now and the parts that drive the stitch length wear out over time. Here is a list of things you can check out to see what is causing the short stitches.

Lift the pressor foot lever to the raised position and lower the stitch regulator all the way down, then tighten it in back
Lift the pressor foot lever and see if you can wiggle the foot forward and backward more than 1/16 inch either way
Feel the bottom of the pressor foot to see if the teeth are still viable
Tighten the pressure spring along the back of the machine to exert more downward pressure
Loosen the pressure spring in case it was too tight
Check the throat plate cover for burs or gouges that might grab the leather as you try to advance it
Make sure the bobbin case tension allows the thread to flow freely, but with some tension. If too tight the stitches may be pulled short from the bobbin thread.
Check the top tension to make sure it isn't so tight that it drags the work forward against the foot action.
Any of those things can affect the stitch length, especially if the top tension spring is too loose, or the teeth are worn off the bottom of the foot. Too much thread tension can shorten the stitches by fighting against the foot action. But, the most common problem with hundred year old patchers is a worn out stitch regulator puck inside the rotating pressor foot assembly, where it is attached to the bottom of the head. When the needle moves up the mechanism lowers the butterfly housing, causing a puck to pivot inside the housing. It is the amount of downward pivoting that determines the maximum stitch length. If you have lowered the regulator and set it firmly on the back of the two rails that are part of the foot assembly and the tensions are all decent, but the stitches are very short, the puck is probably worn out inside the butterfly housing.

You may be able to get replacement parts from Bob Kovar, at Toledo Industrial Sewing Machines. Otherwise, disassemble the head of the patcher and unscrew the foot mechanism. Send the moving ring and the housing it revolves in to a machinist to have some bronze weld added to it and shaped to minimize slack without binding. I did this on two old patchers I owned and restored the full stitch length to them.

Again - compare numbers - the machines are different.

http://www.horsenharness.com/SINGER.html  Totally nuts prices for used (probably worn?) parts - thats ridicules. Before you invest in used pinions and parts better look for a different / later model machine.

Rebuilding the shuttle area? You mean the inside where the shuttle oscillates? I never heard of that. The shuttle carrier has a spring with a ball tip, that ball tip presses the shuttle against the casting and when the shuttle tip is not too worn and the ball on the spring is fine you most likely just have to adjust the needle holder a bit sideways.

As far as I recall the early 29K´s do not have a timing eccentric so the condition of the pinions and racks are essential. The 1st thing I would do (if it is not sewing when cleaned and reassembled) is buying a new quality shuttle (TOWA made) - I don´t know how good or bad the Chinese made shuttles are. Towa shuttles are excellent.

Other question - have you pulled out the shuttle carrier with the attached pinion from the top side just as shown in picture #7 / #8?  Or have you opened the gear box plate and removed the parts bit by bit?

Chrisash thanks.. when i get to it i am sure there are lots of excellent psots i will need to revurw like this.

Constabulary - yes i will make sure part numbers are all accurate or deal only with folks who know.

The assembly woth the hear pictured was spare and looks like the disc area is broken

 There is an assembly in the machine i have not pulled and wont unless function trouble shooting warrants.

Thanks for the tip on reliable shuttle source.

The rebuild i am talking about is where the arm cast metal appears chipped on the arm just around the area where the shuttle etc sit in. This i can reconstruct. It looks like some aress alreadt where so it looks like ot may have landed or beem struck on the end of the arm at some point.

All this is much appreciated and i will refer back
