QuestionMark 132 Report post Posted June 12, 2017 Any ideas on how to get a jack for a guitar cord to stop loosening on an archtop. Happens on my ES 125TC. QM aka Jazzman Jeff Quote Share this post Link to post Share on other sites
L5Larry 202 Report post Posted June 12, 2017 I would use and external tooth lock washer on the inside, just under the wood. http://www.homedepot.com/p/The-Hillman-Group-4-Stainless-Steel-External-Tooth-Lock-Washer-70-Pack-43798/204794826 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. Quote Share this post Link to post Share on other sites
QuestionMark 132 Report post Posted June 12, 2017 Perfect. Thanks. I will stop at Home Depot and buy the lock washer and place it as you suggest. Thanks, again. QM aka Jazzman Jeff Quote Share this post Link to post Share on other sites
Drog 43 Report post Posted November 13, 2017 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. Quote Share this post Link to post Share on other sites
Guest Farnsbarns Report post Posted December 10, 2017 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. Quote Share this post Link to post Share on other sites
