top thread shredding.... tried a few things to fix but no luck

[DrmCa]

Organ should be fine. I found no difference in performance among Organ, Schmetz and GB.

You might be just stretching your luck putting too heavy material through this machine. I own 553 and it does not like heavy stuff. It will stitch 4 layers of denim no problem, but give it leather and it will skip and shred nylon, poly or polycore thread which works fine otherwise. 55x series is a textile machine after all. It did stitch marine vinyl no problem though.

Make sure you take removable parts like throat plate or feed dog off the machine before smoothing them with a dremel tool, diamond file,  or abrasive cord. You don't want the abrasive grit falling into your machine or hook.

Nylon should work as long as your machine is in good shape to sew it.You might want to look around the outside of the hook(the piece of tin held on with 4 screws),the needle can hit it & put nicks in it.

yup, i removed the plated first before drilling.... 

so i started playing with the tension and making it loose and tight....  making it loose helped but the sticking was very poor.  anyway i got the tension back to normal and the problem is still there.. i started sewing really slowly and i kinda hear it get caught on something... not sure what..??

i think it may be the tread spool,, i set it up so it would flow better, ill tried just having extra thread loosely sitting there and it sewed okay...

There's your next step -find out what causes that. Tilt the machine back and hand-turn a few stitches with material under the foot while carefully observing how the thread wraps around the hook. Perhaps your bobbin case opener arm is not doing its job. The thread apparently snags somewhere and that is very likely the cause for your thread shredding business.

I would run some textiles through the machine and try getting the tension back where it sewed a great stitch.

These issues have damaged mine more than once by bending the needles enough to hit something when motor is powering through.  Although if it hand wheels through the cycle easily then its hard to tell so patients and perseverance.

That noise while cycling sure sounds like a clue. Seems the burrs get started and needles get redirected in short order.  

I think this is compounded with leather material vs canvas types.  I need to place an order for some more fine abrasive cord. Wonder if the guitar shop has some?

good luck there

There is a reason why leather causes stitch and needle problems to be revealed where cloth has no problems being sewn. The leather is denser, thread tensions are higher, and this pulls and deflects needles to the left as you sew. Thinner needles (#110/18) deflect more than thicker ones (#200/25).

Needle deflection by the thread can be controlled somewhat by lowering both the top and bobbin tensions and using one size larger needle if necessary. This combination will reduce deflection of the needle, but may lay a lighter stitch than higher tensions do.

Yes I agree and understanding a bit.  In my thinking the semi-suede used can actually have leather in it, though from some upholstery points a lot is "if leather" is probably ground up bits and then sprayed onto the textile backer.  

Im wondering what a photo could help here and so just recommending a restart.  Possibly any mention in layers and any other recent issues. 

Thanks for the tips and have a good weekend

I believe they were Organ brand needles that I had the issue with.
