Dreams,
I've ordered from them(West Fl. Components), they ship fast, have good prices & great products. I've got the 14,18, & 24(somewhere) gauge tubing. I was thinking about trying the 7 & 8. I'm thinking the 14 will be the ticket for me(only $.30 a foot!). A juice box will be a little later on for me. Right now, I'm working on a battery box with a box battery in it.

Well, not really a battery box, but, close.
Bummer about not being able to sell w/o registering as a supplier. But, please don't be regretful about posting a how-to. It's said what goes around, comes around. You've earned a big one for this!
I know about the honesty thing. If my family doesn't want to know the truth, they don't ask. I'm not a good liar.
Looking forward to your how-to, hope you don't mind if I turn it into a pdf file. I'll be able to keep it that way.
Have a great one!
