JLSleather Report post Posted March 2, 2015 Anybody know what causes this cobra to knock the end of the needle? Bends outward -- ONLY in reverse. And I don't mean "flex" the needle, I mean there's a crisp sound, and then the needle is destroyed. No detectable damage on the shuttle assembly.

Red Cent Report post Posted March 2, 2015 About the only problem like yours is when I cannot get a thick piece of leather flat as in the closing of a western holster. I finally started soaking the fold, got everything flat and sewed. Now the reverse "only" thing is puzzling Quote Share this post Link to post Share on other sites
Gregg From Keystone Sewing Report post Posted March 3, 2015 What model machine is this? If you take the hook out and things are only hitting in reverse, the next thing to check is if the feed dog is hitting the needle when you reverse feed. I would take the needle plate off so you can best see what's going on in there. Good luck! Quote Share this post Link to post Share on other sites
JLSleather Report post Posted March 3, 2015 'Preciate ya fellas.. checked all the above Cobra 4 machine. I took the needle out, took the hook/shuttle assembly out to clear any debris (like maybe I'll find the tip of a needle down there?), brushed the tip of the hook with some 600 grit wet, cleaned everything back as far as the feed dog, oiled until my shoe was full (actually, thought i might flush something too small to see). Ran the machine a bit without the plate or a needle, watched the oil coat the race. Nothing 'crashing', but I'm getting the occasional skipped stitch (which never happened before today). Guess I'll check it again in the morning. After over an hour in there, I can say that it is NOT worse than it was! Quote Share this post Link to post Share on other sites
