This instructable walks through the process of making a mouth-friendly edge on an aluminum bottle turning it into a Cool Reusable Metal Tumbler Cup.
The steps outlined here are, stand-alone, instructions to make a complete Metal Tumber from an aluminum bottle; suitable to use as a lightweight tankard for all your favorite beverages.
(I recommend the chilled kind. Remember science?...aluminum is an excellent heat conductor; you don't want hot cocoa burns on your fingertips as well as the tip of your tongue!)
However... those of you familiar with the Aluminum Bottle Backpacking Stove,
( http://www.instructables.com/id/Aluminum-Bottle-Alcohol-Stove/ ) will also recognize the technique demonstrated here, as a means for creating light weight cooking tools to accompany an alcohol stove.
The video below shows these Aluminum Bottles & Tumblers in use as a lightweight backpacking cook / storage system.

The bottles are obviously used for beer (and I know at least one soft drink) however, availability of either (or any for that matter) varies by region.
As an added note: I had reservation about posting an instructable that featured an alcohol container as it is not appropriate for all. I would have perfered to use a soft drink bottle however due to availability in my area, I only have found the beer bottle variety.
But ultimately, its the aluminum bottle that we're interested in, not necessarly the beverage. Dispose of the contents as you deem appropriate, or seek out empties through another source.
(Along the same lines: I am pretty sure not everyone who has built a bar-b-que from a steel barrel personally bought, and consumed the 50 gallons of Crude Oil inside to get to an empty drum.)

Thanks
1. Make sure the cut edge is free of saw nicks, burrs, and file marks. There should be no edge imperfections that could initiate a crack.
2. The cut edge should be flat. After any cutting or de-burr filing turn the edge on emery cloth placed on a flat surface. Removing material this way eliminates high spots on the edge and ensures the edge has a full wall stock thickness.
(see the first photo below)
3. When the flare is started make sure the edge is not too wide.
4. When rocking the bottle on the wood to roll the edge, do it gradually and evenly. It will take a number of turns. Periodically stop and examine the edge to make sure it is rolling evenly. Adjust downward pressure accordingly.
5. Make sure the bottle stays round while rocking the bottle do not apply so much downward force that the edge of the bottle takes on an extreme oval shape. Stop occasionally and use the dowel or push bottle over the neck end of another bottle or use a PVC pipe connector (photo 2 below) to "stretch" the edge back into round.
Good luck and keep trying. Let me know if you succeed.
I didn't think that putting such a neat finish on the borders could be done by hand without some kind of weird specific tool.
I'm doing this to my alcohol stoves soon :)
Thanks a lot.
Hehe You don't know my uncle down in S.E. Texas!
This is really cool. This was part of this week's email and the timing is perfect- it helps with some ideas for something I'm looking for. As a biker, I find it a pain in the butt to fill the tank. The McCuff is a rubber-like device that makes it super easy, but you have to put it on, take it, etc. (I'm lazy, I know) So I'm thinking of trying to build something out of aluminum or stainless that stays in the take-fill hole and is collapsible. Basically, you'd open the fill hatch, lift the multi-section device with a twist (which locks it in the 'up' position, fill the tank, and collapse the device back down with a reverse-twist, close the hatch and go. Any ideas how to add your brilliance to my idea and make it, you know, actually work?
