29K Bobbin Shuttle Issue

[xenajo]

Hi there

The thread is not being caught by the shuttle hook, it appears the hook falls short by a couple of mm so the thread just misses it. Any advice on how to adjust it. Will post a photo showing the point where is just short of catching the thread shortly.

Thanks

What subclass has you 29K? Some have a timing eccentric some do not. Do you have an manual for your machine? Maybe the hook tip is worn. For uploading pictures click the brown MORE REPLY OPTIONS button next to the black POST button.

If your patcher has a ~7/16" hole in the lower section of the front right of the head, you probably have an adjustable timing model. You can stick a large flat bade screw driver through the hole and angle it into the large slotted eccentric bolt that couples the mechanism from the top to the racks inside the arm. You may need to loosen the locknut on the inside of the adjuster couplings first. The offset bolt allows for advancing or retarding the hook timing by about 1/8 inch.

If you don't have this adjustment in your patcher, you'll need to replace some or all of the gears and racks under the left end of the arm.

I have a 29K 1 here is the photo of the bobbin and shuttle

I have worked on a 29K4 and 29K3 and both had not timing eccentric so I`m sure your also has none.

Are you using the correct needle system 29x3 / 332?

Your thread also looks quite thick (maybe just because of the close up picture) what needle size and thread size are you using?

You can try to move the needle holder a bit toward the the hook. Loosen the top screw on the needle holder an try to move it a bit to the right. Needle holder could be quite tight...

Isn't the tip of the hook broken off in that picture?!!?

I just got this machine which needed a bit of a clean up and a few small parts. The needle pack that came with it are 29x4 3 size 22, the thread also came with the machine so I am assuming this was used with the machine as it was in the small wooden draw of the machine. The needle is pretty much rubbing against the shuttle so I it looked good to me, don't think it can get much closer. When the shuttle is in motion it just seems to be just short of catching the thread. If I move the shuttle with my finger to push it just pass the needle it seems to pick up the thread.

No the thread is covering the tip

Then most like the gears are worn or you need a new hook - maybe the hook tip if worn. The hook tip should pass the needle but not touch it (that wears off the hook tip) so I´d move the needle holder a bit to the left.

29x4 is the leather needle so thats okay. I´d probably try a thinner thread and maybe a smaller size needles though 22 should work fine - but you never know these very old machines can be quite self-willed sometimes.

Open the throat plate and see how far you can rotate or wiggle the shuttle with your fingers. If it has 1/8" or more of slack, the gears are worn out. If that's the case and the machine was using anything thicker than #92 thread, you can guess that the oversize thread wore it out.
