New Pot Lid

I was weighing parts of my cooking kit one day, and realized that the lid of my MSR kettle was pretty heavy in comparison to the pot, wieghing 36 grams (1.27 oz). I decided to make a new lid out of some thick aluminum foil, and the result is a total savings of 29 grams (1 oz)! My new pot lid weighs 7 grams (0.25 oz). I used a piece of nylon cord for the handle. Here's a picture of old and new for comparison:

Here's a picture of the MSR Kettle with it's new lid, weighing a total of 97 grams (3.42 oz).

Enlightened Pocket Rocket

I decided one day to try and shave a little bit of weight off of my trusty old MSR Pocket rocket. Unaltered, it's a pretty light stove, and weighs 87 grams (3.07 oz). I thought it shouldn't be too hard to take a little bit of weight off of it, and the result is a 71 gram stove (2.5 oz), with a total weight savings of 16 grams (0.57 oz). The modifications I did are:

-took off the nearly useless mini windscreen
-ground down the inner part of the potstand legs
-ground down the aluminum stove base (reducing by far the most weight)

Lightweight windscreen system

Windscreens are always a little bit of a problem, especially if you're trying to make them lightweight. I've designed this windscreen system to use with my Pocket Rocket. It has an adjustable ring, and can accomodate a small or large diameter pot. The base mounts directly onto the stove. It holds itself in place with its own weight, and creates a microclimate of heat around the bottom of the pot, vastly increasing the efficiency of the stove. With this system I can boil 2 cups of water with around 6 grams of fuel. I chose to use titanium foil because of it's durability and strength to weight ratio. It's also easy to cut with sturdy scissors or a utility knife.

Material: .005" Titanium Foil (base) .002" Titanium Foil (ring)

Weight: 17 grams (0.6 oz)

Here's the base mounted on the stove:
