Refilling
Being able to refill your fuel canisters gives you the the option to adjust the amount of fuel for a trip, consolidate fuel from partially empty canisters, and use cheaper fuel (especially in the case of propane). Unfortunately, liquefied gas canisters used for backpacking are generally considered nonrefillable. Butane canisters are generally too thin to "safely" reuse over and over again and lack bleeder/dump valves. The heavy steel cylinders used for propane canisters are considered unrefillable by the manufactures and possibly by law (for resale). That said, if it is possible to refill plastic butane lighters, it is likewise possible to refill metal butane and propane canisters - the real question is whether it is safe or not. The following information is for educational purposes only and in no way can refilling canisters marked "Never refill this cylinder," "Do Not refill," etc be considered completely safe. Do so at your own risk.
Propane Canisters -
Heavy duty propane canisters such as those sold by Coleman seem well suited for and can be easily and very cheaply (1/6 cost of replacement canister) refilled from larger canisters with a brass coupler (show below) or with a fabricated homemade adapter. The key is to not overfill the canister, as that would guarantee a leak after it warms up.

To ease filling you may need to stick your cylinder in a freezer for half and hour or more to liquefy your fuel and decrease pressure in the canister.
To help avoid overfilling, you can fill the canister while it is at an angle so that air/gas is trapped in the top most portion of the canister. The trapped gas will prevent the cylinder from overfilling. You can also use the bleeder valve to dump any extra fuel. You can also record the full weight of a new canister, weigh your canister after fueling and add/dump as needed. Shake your canister when you are all done to make sure that it isn't "topped off."
Butane Canisters -
These canisters can be very thin and are not made for long term abuse. If you are trying to save money buy using fuel not made for your stove, there are easier and less problematic options, such as using an adapter that allows your stove to run cheaper fuels. Also see this B (http://www.bushwalking.org.au/FAQ/FAQ_Stoves.htm#Refill)ushwalking (http://www.bushwalking.org.au/FAQ/FAQ_Stoves.htm#Refill) Stove site for more information on refilling.
That said, a Burton FuelTool or butane canister designed for refilling lighters can be used to refill Campingaz and PowerMax canisters without modifications.
Cheddar Gas Valve designed for refilling tanks for model trains
Two of these with a hose or tube connecting them should make a great refill tube
An adapter can be easily fabricated from two Brunton Fuel Tools, old stove parts, couplings, etc. Or, just about any combination of adapter can be purchased from www.alva.ne.jp (http://www.alva.ne.jp/)Babel Fish (http://babelfish.altavista.com/babelfish/trurl_pagecontent?url=http://www.alva.ne.jp/&lp=ja_en).

Running Propane in Butane Stoves -
You may need to add a pressure regulator to prevent damage to your stove if you decide to hook a butane stove to a purely propane canister. Filling a light duty butane canister with 100% propane is easy to do and may give you the best lightweight cold weather cook system around, but it may also be unable to handle propane pressures, leading to an explosion and death. This is of course worst case speculation.
Running Other Gases -
Some gasses, such as acetylene, require a stabilizer to prevent violent decomposition and explosion during storage and transport. Hotter burning gasses tend to burn at higher temperatures close to the stove and may damage them or cause a serious incident. Use of gasses other than butane, isobutane or propane for refilling empty canisters, camp stoves and/or lanterns present a serious and real danger. Do not use fuels your stove isn't designed for!
