Small update:
I started with a SS tube and drilled some test holes.
After that, i have drilled my first 10 holes. Still 30 to go!
Every hole needs to be perfect...Man....i am no monck.....I hate that work...pffffff
After drilling, i have to bring it to my metalshop for polising the inside, or maybe chroom?
They also have to weld an smaller inlet and outlet tube on the ends for this 1 inch diam tube.
Its 1 inch by 4 inches long.
Because there will be 4 different leds in it, i have to make 4 different driving circuits.
But, he. If you try, then do it right...
See what this all bring to us.
