Whip finish

[MCG1]

Try a new spool of thread, or a new bobbin. Other than that, with your experience, good luck. I agree with you, glue isn't required, unless you're selling jigs. ⁹

Hmmm I've never had that happen, it sounds like you know what you're doing with the tool.

I usually do 4 turns and pull tight but I do always apply head cement the thread and let it really soak in.

I use a touch of glue to lock everything down. I have never had one come apart while crappie fishing but white bass can be hard on a jig. A dab of glue is cheap insurance.

Never used a whip and never had a problem. I always coated the thread with Sally Hansens super clear finger nail polish. Works great and a lot simpler and faster than a whip.
