Insulated Canteen From No-Refill Propane Bottle

Insulated Canteen From No-Refill Propane Bottle

Cool Instructable from user hpstoutharrow. Of course these propane bottles are not meant to be opened, so you have to be careful to follow a sensible procedure, but it seems to me like hpstoutharrow has done a good job in providing that. Commenters there seem to agree.

Once any residual flammable gas is safely vented, both valves are removed by drilling, and the bottom of the bottle is cut out to insert a 20 oz plastic beverage bottle, which has been shrunk slightly by exposure to boiling water. The neck of the soda bottle protrudes where the tank’s center valve was, and is secured there with an o-ring. Spray-in foam insulation holds the liner in place and insulates its contents from the metal bottle, and the bottom of the tank is reattached for appearance’s sake. [via Hack a Day]

How-To: Ultralight camp pot from Heineken “keg” can

How-To: Ultralight camp pot from Heineken “keg” can

In the summer of 2002, Heineken introduced its 24 oz. “mini keg” can in the US. Besides having twice the volume of a normal aluminum beverage can, the “mini keg’s” unusual design includes a number of ridges and rings that make it much more rigid. Sometime around 2004, so far as I can tell, ultralight backpacking enthusiasts began experimenting with using the new can design as a cooking pot.

The community has evolved the design of these cooking pots to a remarkable extent, and although there seem to be as many variations as there are builders, a few common features seem to be emerging:

1. The top of the can is removed with a side-cutting can opener and preserved for use as a lid. The tab may be bent up to provide a handle, or a small knob may be attached.
2. The side of the can is wound with 1/16″ fiberglass wick to provide an insulated gripping surface
3. An elastic silicone wristband is stretched around the rim of the can for drinking comfort.

I’m sure to screw it up if I try to give any particular person “credit” for any of these ideas, but the embedded video overview from Minibulldesign Cult gives the best general overview of the idea I can find. And Rick of Wilderness Survival Forums has produced a good phototutorial describing the fiberglass winding process.
