Scott thanks for remembering that post and for passing it on, I appreciate your interest!
Peteski and Randy - thanks for your nice comments, truly appreciated.
No the flame does not make any rumblings when it lights up. That MIGHT be the next attempt, it would be cool.
Randy- here are a couple of images of flame without the cotton.


Add a little cotton and you get something like this...

Yes, there are 5 LED's plus 2 very small mirrors that I wrapped the cotton over. I dry brushed a very small amount of red onto the cotton and then, after getting it shaped as I wanted, I dry brushed black fairly heavily. May need a bit more black but I will wait to see after it is put on layout. I wish I was smart enough to think of this process but I got it off of a Y-T video made by a guy making flame throwers for war games.
Thanks for mentioning the sound as I can remember here at the Chevron refinery the flare sounded like a jet engine, at times.
Be well,
Carl
