can i use locktite on it.

As long as you use the blue one and not the red one (permanent) you should be fine

 

Or you could use a spring washer. Same concept as a lock washer, but very thin.
Nail polish and super glue will also work.

 

I’d check the threads on both the input jack and the threaded washer; if they’re bad it might need replacement. Get a switchcraft.

 

Where's the input jack on this Lakland?

The spring washer sounds like a plan. I would expect there to, already, be a star type locking washer on the inside of the output jack assembly. Is this a Skyline (chili) or a US made one (looks like a Korean[?] one, to me)?

 

The Red one is not permanent. You can heat it with a hair drier for about 20-30 seconds and it will come loose as if it wasn’t ever there. The blue one is not affected by heat.

 

How well does the finish on the bass in the area of the heating hold up?

 

Such an elegant looking bass!

 

Have you taken the jack plate off and inspected the inside for a spacer? It is unusual for a standard 1/4 jack to be almost flush with a thin jack plate like that. If it is just a case of not enough threads, replace it with a better jack.

 

yep-i would be hesitant of applying glues etc to such a nice object too-my fender tele '77 custom i've had sympathetically serviced (as in, not by morons who'd destroy its classic build) twice in last 30years-first time new bone nut made-2nd time 1 replacement pot-id get it to someone like that-personally recomended-check WHY it keeps loosening, rather than "sticking plaster" the priblem....

 

This is a Purple Loctite job, just saying.

 

if you can get a grip on it from the inside and crank on the washer from the outside, it should stay. But ya a little locktite should be fine.

 

yeah-its just me personally-for instance-when i decided to get all my knives etc sick sick razor sharp, it took a little while, experimenting on unimportant kitchen knives, until i got the whetstone technique down real good-in same way, im such a DIY-not-intuitive-but-able-to-learn-most-things type, as i havent got rows of £50 pawn shop guitars to practice on-id always take my 4 babies to someone who does guitar repairs all day, every day....thats just me tho....✌️✌️

 

The jack is mounted to a plate that can be easily removed from the bass to see.....



..........with the jack loosening.

 

So you should be able to pull the plate off, get some grip on it, and give it a good turn?

 

Someone has to ask - What is the best loctite for metal?

 

Go to the hardware store and find a spacer to really get the lock washer to bite in when you tighten your nut.
Maybe get a wider nut if you got one of those super skinny ones with your jack.
Slim o-ring around jack will help keep some tension as well.

 

Blue loc-tite or a lock washer will do exactly what you want.

 

Talk to LocTite.

I took the seminar.

I assemble with it daily, about 6 various bottles on my bench.

222 is the Red stuff. Yes, you can loosen it with a hairdryer, they usually recommend over 300F to loosen, which is not good for plastics.

242 is the blue stuff. Still won't back out on its own, but user removable at a lower torque.

Why use heat if not needed?

Its called welding
