I am really late to the party, I know...... But is there an specific adjustments I should be making when down stepping from a #22 needle and 138 thread to a #20 need and 92 bonded nylon thread? I am new to industrial machines, and we picked up a Cobra 26. It came with a #22 needle and a spool of 138 thread. I followed the manuals instructions to load a new bobbin, change the needle and rethread the machine with #92 bonded nylon thread. I checked to make sure it was done per instruction manual and Al Bane, and I am pretty confident I did it correctly. My problem comes when I try to stitch. I am using 4oz waxed finished leather in an attempt to make a tote. I was snapping thread, so I adjusted the tension and solved that problem, however, the hook is not catching the top thread (it never did, even before I moved the snapping thread issue). I have searched, and googled, and cussed.... I decided to switch back to the #22 and 138 thread to see if I would still have the problem, and magically.... there was no issues. I am probably not wording my question correctly and I apologize. As I said I am very new to this and any help would be greatly appreciated. Stephanie
