OT Maglite threads

For the many Maglite fans:
Someone here recommended Burndy Penetrox A for aluminum-to-aluminum
and aluminum-to-copper threaded electrical connections.
I picked up some yesterday, tried it on the tailcap of my 2D Maglite,
which is old enough that the anodization has worn off of the threads.
WOW! The tailcap now screws on very smoothly.
I found the Penetrox A (catalog number P8A) at a large electrical
supply house -- for half the price of buying it online.
BTW, Gunner, I'm making progress on the Luxeonated MX991\U. I think
I have a scheme for driving a 3W Lux from 2 D cells, full output down
to 0.9 volts per cell. A 1-watt would be more "practical" because of
longer battery life, but I think I'm gonna go 3 watts on this one
just for fun.

"Pax Americana is a philosophy. Hardly an empire. Making sure other people play nice and dont kill each other (and us) off in job lots is hardly empire building, particularly when you give them self determination under "play nice" rules.
Think of it as having your older brother knock the shit out of you for torturing the cat." Gunner

On a Mag light, the threads themselves are supposed to be anodized and the electrical contact is made on the faced end of the tube, and the mating surface on the cap. If you have a Mag where the anodizing is not worn off unscrewing the cap will break the contact. IIRC Mag recommends using Vaseline to lube the threads. Probably a lot cheaper than Penatrox.

Vaseline is definitely cheaper, though $8 worth of Penetrox would be a lifetime supply. I've used Vaseline on aluminum threads. The Penetrox works a LOT better. Hams who use it on aluminum antenna parts outdoors also say it works very well. Conductivity aside, it is designed to have very good anti-corrosion properties.

It is not so much the $8 but I think it would do you no better than ordinary slickym. I have never noticed much corrosion in my well used Mag lights even the penlight that spends a lot of time getting drool on it when clenched in my teeth.

YMMV! The hams that use it on their antenna towers sure like it. For dentally-mounted flashlights, may I suggest chocolate frosting as a more suitable lubricant..... or perhaps K-Y gel in the new herring flavor....
