First off, THANKS everyone!!! And sorry for not responding earlier, I've just been swamped :[
Pritorian, I've seen that a few times; it may just be a bit too ghetto for me
After reading that link, mfpmax, I was thinking about copper tubeing (gmat), and still am a bit, but after reading your post, nicozeg, I relaized I've got the PERFECT thing.
It's an old bucket I got abroad, been dragging it around for years; it looks like it holds 2.5-3 gallons, is PURE 1/8" copper, and I have two of them. These sound good?
If y'all think it's ok, I'm going to start ordering guts.
THANKS AGAIN EVERYONE!!! Really, thanks
