Hi Eric (gottaknow),
Just been looking for info about threads for my Lk´K 1852 tacker i have and came across your post. Great info cheers.
I am wondering, have you had much success with 100% polyester thread? I am using polyester t60 or a thicker thread t90 (equivalent) and i'm having trouble with consistent cutting and well as making the last lock stitch hold in place.
I have replaced the blades , adjusted the knives and knife timing, and reset the hook timing and needle bar. It is making a lovely looking stitch and works quite well when i use thinner poly cotton on the bobbin (thanks for the tip! def makes a nicer stitch underneath) but I need to use poly thread only.
Any tips welcomed! Thanks!!
