Dorcy 1AAA question

[thartley]

Hi,

I find that when I carry my Dorcy 1AAA on a key ring in my pants pocket, it unscrews itself to the point where the battery falls out, and it does this fairly frequently. Has anyone else experienced this and/or have any suggestions on how to modify the light to keep this from happening?

Thanks.

I got a short (~3/4")piece of clear plastic tubing (1/2" I.D. - from hardware store) and stretched it over the tail cap so maybe 1/4" extended over the rear body. It provides enough friction to hold the tail piece in place - and also gives a cushion for your teeth if you ever hold it in your mouth. Doesn't look too awful.

How about gouging the threads just a bit to add some friction?

Do you think that a thin strip of Al foil will help?

 

[bobisculous]

I think alluminum foil may rip up to easily. I bet teflon tape would do the trick. That or get a slightly larger o-ring on there, to tighten it up. Either way, you will also get a slightly more water proof light. Although, I took one of those in a pool once without any modding, and it survived. Had water in there pretty badly but still worked fine. Aired it out some and good as new.

Anybody find a source for o rings which fit and tighten up the Dorcy 1 AAA or the CMG Sonics, let me know. Please.

 

[markdi]

almost any hardware store or auto parts store should have a selection of o rings

I use Parafilm to give enough hold to keep lights from unscrewing. It is usually used to seal laboratory tubes. The Parafilm stretches to about four times its original size then I wrap the threads of a light. One roll lasts forever.

WHAT THE HECK IS PARAFILM?

 

[thesurefire]

That parafilm stuff looks pretty neat.

 

[Lurker]

Teflon tape on the threads will tighten it up.

 

[wholeflaffer]

Won't Teflon or Parafilm placed on the threads reduce or eliminate conduction of electricity from the negative terminal in the endcap to the main flashlight body?

 

[Lurker]

No, the tape won't prevent conduction because the path of conduction is not through the threads of the endcap. The negative terminal spring is mounted on a disc-like piece that hits the end of the tube when you press the button or screw-down the endcap.

 

[eebowler]

Oh, that makes sense. That was why I suggested foil in the first place.

 

[TrueBlue]

Like Lurker said. And if you use an airbrush like I do the stuff is great for masking. I can make so many pretty color lights with the airbrushes and Parafilm.

If you trim the rose bushes the Parafilm also makes a super bandage.

You'd only put the Parafilm on the threads but not on the very edge of the light.
