new collar for E2E, very cool but question

[keithhr]

I just got a couple of brass collars for E2E lights, screwed it on and placed the screw into the dimple towards the end of the tail that marks the on off point for lotc. Should I use something to lock it on to the tail or would that be a bad idea in case it had to be removed. It seems very secure with the screw going into the dimple(hole). I didn't use a shim because that slight hole seems to be a good place to screw down. If I used just a shim like some have done it seems as though the shim would make friction the only locking mechanism. It's very cool because the collar almost acts as a handle to turn the tail cap into different on off positions.
After checking the button, it seems that the button will unscrew from the thread so I need some kind of locking paste, I can't recall what some of the prvevious recommendedations were, something like locktite? , which I've never used.

Yup, Locktite is a good choice for the button. Also, you can crank down on that button pretty well with a thin piece of grippy rubber in your hand, or very carefully with the protected jaws of some pliers. I have mine on so tight that it won't go anywhere....PLUS I have locktite on it. You can pick up locktite at most hardware stores. It is just goop that creates enough friction to keep fasteners from coming off until you WANT them to come off.

thanks Darell, I'm glad I have two of these collars, it will be a nice way to carry my Nascar modded E2E/P61 and my E2E/Kl1 that cm is putting in a W4W LS for me.

Ya know... I'm not sure it would make all that much difference, but I don't put my set screw in the divot. I just let it hit on the knurling somewhere. That leaves the set screw out farther for the button to grab. The main reason I did it NOT in the divot is because if the set screw makes a scratch, it won't be as visible in the knurling. Believe me - it holds just fine NOT in the divot.

I agree that you must use thread locker. Loc-tite Blue should do. Another guy lost his McLux, because he did not lock the button.

I posted elsewhere that I slipped a piece of stainless steel "shim stock" behind the set screw to protect the finish. It works great! However, small quantities of shim stock are not easy to find. I just happen to have some from years ago when I was making knives. I found sheets of shim stock at various industrial supply houses, but they want you to buy too much.

As a work-around, you might use feeler gauge leeves.
