Any ideas on how to get a jack for a guitar cord to stop loosening on an archtop. Happens on my ES 125TC.

I would use and external tooth lock washer on the inside, just under the wood.

I like my jacks to be flush with the wood on the outside, so this lock washer on the inside would be in conjunction with a clinch-nut and/or flat washer. Then you have to be able to tighten it all up without twisting off the wires. I use a pair of large curved jaw hemostats for this by grabbing the base of the tip spring contact, either through the f-hole, or through the plug hole itself. Tighten outside nut securely (nut driver, or open-end wrench depending on where the clamp is), but not too tight.

Perfect. Thanks. I will stop at Home Depot and buy the lock washer and place it as you suggest.

Thanks, again.

Here is what I do. On the exposed part of the jack thread, put a little bit of clear nail polish. The nut will not spin off, if you do need to do maintenance you can break the seal easily. Works like a charm.
As a caution when applying the nail polish, cover your guitar with a cloth in case you drip any. [biggrin]

Yep or a drop of locktite.

Threadlock suck as locktite. There are 2 grades. One you won't get undone without heating it to 700 degrees, and another, which you can simply brute force off. You want the latter.
I'm not drunk, you're blurry.
