polishing process looks like Nevr Dull?
Black stuff? probably just the polishing paste on newspaper.
I used 600 grit then 1000 grit wet & dry then 0000 wire wool then…
That’s a tall picture…
I think the black stuff asked about was what’s inside the tail of the pill in picture #20 from the top…
Ah, duh - i’m tired now lol. The copper slug was all i had so to fill the rest of the empty space that’s a jb weld and silicone carbide mix. Didn’t catch on because it’s grey…
Yeah i consolodate the pics for less work/ hassle.
You have a lot of patience 
, great mod!!!
WOW!! thats really impressive. Great work. My hands cramp and fatigue just scrolling through those pics.
Amazing work :sunglasses:
Thanks guys :+1:
Wow, that is a chunk of artwork!
Beautiful work!
Im amaze with your copper pill .
so nice and shiny
That is nice work sir. Truly hand made. I would be proud of that rig! How long did it take to complete once you got going?
Thanks for the comments guys 
Hello mate, good to see you again.
I think maybe around 3 hours altogether.
The most difficult part was precision fitting it so the optic presses against the host glass and the aluminium ring presses against the rim inside the head so there is solid contact all round when tightened.
Nice Work!!! Thanks for sharing. You guys that do that are just tough!!! :+1:

Well done, very nice finished light.
Thanks, nice compliment from you guys 
Awesome sharing !! Thank you.
Looks like a new project for me
Now where can I find copper
CRX, your craftmanship skils never stop to amaze me! :+1:
cheapest copper I could find was in home DIY shops, like Home Depot, Lowes, … paid about 1.5 $ for a short copper pipe that should be good enough for 2 P60 dropins (if you’d follow this build or something similar).
copper rods on the other hand… are not necessarily available in the regular home repair shops. The home depot I went to didn’t have them.
