There's the kind of DIY that looks like B.A. Baracus rigged it up in the back of his van, then there's the good kind. Erik Anderson's Recycled Wine Bottle Torch is the good kind, made in classic fashion: He wanted something (patio torches) and was unhappy with the commercially available selection (have you seen Tiki torches?) so rigged something up on the cheap (using parts from the hardware store and empty glass bottles).

Anderson broke out the instructions for all to see and emulate, along with photos so pretty it looks like they were shot and framed by a pro. (Hit the link above to see 'em large.) Says Anderson,
In any of my design work, whether for clients or for myself, I'm most proud when I can find a solution that's highly creative and effective while keeping resources to a minimum. This is totally inexpensive (around $5-bucks). Plus it's a great way to recycle a bottle.

There is one flaw in the design: there needs to be some way to let air into the bottle as the oil level drops, or the capillary action will slow down as the oil level gets low. All he needs is a narrow spacer around the plug to let air in.
All he needs is a quick release mechanism for the bottles, and he'll have a dual purpose lighting system that doubles as a bunch of Molotov cocktails at-the-ready.
Won't the teflon tape that he's using to fit the colar to the bottle break down from the heat? That copper collar must get really hot from the flame. I don't think it is a good idea to heat teflon tape too much; teflon breaks down into some really nasty stuff. Do a web search for safety warnings on non-stick pans, and you'll see what I mean. Heating it above 450˚ (or something near that) will cause it to emit nerve gas like toxins.
These are awesome! I love upcycling, and have a fasination with beautiful wine bottles! Cant wait to try it out!
