with an arc body, turned down to be nice and shiney, for no other reason that...well...to be nice and shiney, i decided that i should put it somewhere i could use it, because it was impossible to turn on with one hand, and i've wanted to try alternative arc mods anyway. i decided that i should go ahead and put that useless arc to work.
i had some nice pictures during the production of this light, but the camera got sick, and the pics were deleted /ubbthreads/images/graemlins/frown.gif
here is the head. the pink stuff is nailpolish i *cough* borrowed *cough* from my sister. this ensures that the large positive nipple of the dcell battery does not ground out on the crimped area of the arc head. the foam was obviously removed. i also enlarged the solder dot a bit to insure good contact (the dcells i'm using have a concave surface in the nipple)
to make the negative connection to the led, i bored a hole in the endcap of a dcell maglite, and made it *just* wide enough to firmly press the arc head (it was turned down previously), and after the head was inserted, i potted the inside of the dcell cap with titanium epoxy, ensuring a good waterseal, and keeping the battery frompushing the arc back out.
here is the head again, you can see that the dcell pushes up tight against it.
here you can see the spring that's used to hold the dcell in suspension and provide firm electrical contact.
here is the spring inside the light, showing how it makes contact with the body and the dcell
here it is, next to my mmm and e2e.
i took a dcell maglite, and cut the bottom section off. i used the tailcap with a hole in it to hold the arc head, and i took another endcap and took the threading off, and removed the annodyzing of the body to ensure good electrical contact. i then took another piece, and pressfit it inside the dcell endcap to make connection with the end of the battery. i then took the body and the endcap to the vice and used my superhuman strength to push them together.
the light works the same way as a regular arc now. the mag doesn't use it's threading for electrical connection, but uses a thin strip of bare aluminum on the endcap and the end of the tube, so when they are screwed down to touch each other, the light turns on /ubbthreads/images/graemlins/smile.gif
