Woo-hoo, . . . I love the paint job.

Not a big fan of purple, . . . but sometimes, . . . and this is one of them.

Cannot offer any specifics on "how to" to make it better, . . . but if that was mine, . . . I'd play with it in my spare time, . . . for days, . . . until I got it working again.

Best wishes and all the encouragement I can muster up, . . . is yours, . . . go for it.

May God bless,

Dwight

Awww thank you my friend. Very kind of you.

@Cymro29k3 moved your post to leather sewing machines.  You'll get  more contact with the gurus here.

Thank you kind sir. I've no idea what I'm doing here. It doesn't help that I'm on this site on my phone!

When I look at your pictures it seems there is a wrong part on your machine - the "vibrating presser lifting lever" appears to be too long. I guess its from a different / earlier 29K model. See big red arrow I added. Or it is just the angle... not sure...

I sold this machine a few years ago, it was working when I sold it.  I'm sure that part could have been wrong, if I ever come across another one I will have to compare.

Maybe a video of the action would help with maybe the bobbin cover mover out of the way so people can observe the pickup action

Might have been a shop window machine to get that colour

Sorry for the quality of the vid. It just won't allow me to upload a better quality vid but I shall take some photos.

The feed is out of sync with the needle's motion and position. The needle must be completely out of the material for it to feed. your needle is moving down, passing the plane of the foot, as the foot is trying to feed the work! Perhaps a previous owner replaced the cam on the rear of the main shaft with the wrong part number (e.g., cam for long arm machine instead of short arm).

Also, the foot looks like it is not lowering far enough to get a firm grip on the material. It should come closer to the arm with the throat plate swung away and actually drag on the throat plate when it is locked in working position..

This is so not user friendly on my mobile phone!! I painted her myself.. The quality of the videos I am able to upload are terrible too!!

 

This is so difficult to do on this phone! Yes, all that makes sense. I've noticed that one of the screws holding the hand wheel is broken and a screw is missing from the big wiggly pulley thingy on the main shaft!

Therefore it looks like I probably won't be able to fix it myself. I don't have the tools to remove the broken screw.

Hard to tell w/o sitting in front of it and watching the stitch cycle.

Well - when cranking the machine - in the moment the presser foot moves back (for making a new stitch) and touches the needle plate the needle bar should be in its lowest position and should start rising. If this is not the case it "could be" that the pulley cam is in wrong position on the top shaft.

Beside that - I guess you have the stitch length adjuster on the longest stitch right? Make sure the stitch length adjuster is correctly assembled. The squared frame and the gib have a "wedge" which have to be in a positioned correctly. The wedges give the presser foot bar space for its movement (feeding).

Also make sure foot lift mechanism on the backside is correctly assembled and foot pressure is adjusted as low as possible. Position of the foot lift slider on the leaf spring is also important.

I would like to see a pictures of the backside if you don´t mind.

BTW - very special color

 

As you can see, the foot lift lever has long since snapped and I'm struggling to find a replacement as the current one isn't the correct shape for this model, according to the book/manual anyway.

[Constabulary]

the foot lift lever is an early "push down" lever - modern lever do not fit. I only have seen this once - let me check if I find more pictures... you can ask a welder if he could weld a piece of metal on it to endlong the lever.

EDIT:

I once restored a 29K3 with push down lever. This it how it looks when correctly installed - sorry no other picture

I recall it was a bit odd to install it but I do not recall what the problem was. So it could well be that your lever is the correct one - just broken.

lol thats a harsh colour, daaaammm that must stand out in sight. cheaper then a welding job could be a laser cut piece, a small piece like that would cost you 20 bucks and 5 min of work time from the machine. if you d like pm me i can draw you a dxf for you to send to the laser cutting machine shop.

The adjustment on the back of the flat tension spring is set at its lowest position meaning that foot has almost lift.    As Folker stated, Loosen the wing nut and move the block clamp to the left like in Folker's pic.  That will raise the walk height of the foot.  A lift lever from a 29-4 machine should fit yours.

Hi Glenn and thanks for that. Unfortunately,  it makes no difference if I adjust that wingnut. It does raise the foot but the fabric/leather still doesn't feed. It looks to me like the needle comes down a second or two too early which causes it to pin down the fabric before the foot has finished feeding the fabric through.
