Making air holes in a can:

Note: you can go higher up the can with another row or two of holes to increase air flow.
You can also twist the Cross-Member more to expand the size of each hole

Note: we provide a free P-38 can opener with every set of Cross-Members, so you even have the means to open a can, for an all in one survival tool!

Make your own superior Wood-Gas Stove with the
Siege Stove Cross-Members and two interlocking cans

These new wood-gas stoves have the following advantages over other wood-gas stoves:

  1. Faster and Easier Start-up: Wood-gas stoves take longer to get going than a typical wood-burning stoves. Reason:  The double-wall of a gas-stove inhibits air flow. With the Siege Wood-Gas stove, you can start the fire in a single-can which is well ventilated. As soon as the fire really gets going, simply place the outer can over the inner can with the fire. You now have a double walled wood-gas stove thru which the super-heated air flows by convection. Advantage:  The super-heated air burns the smoke particulates at the top of the inner can. This is the gasifier effect. It results in a cleaner, more efficient burn and will boil water faster. A bit less wood is used too. Two reasons:  (1) The wood’s gases are burned, and (2) Less heat is radiated out from the sides, and therefore, more heat goes to heat the pot on top.

  2. Easier Fueling and more Efficient Gasification: Because a single can Siege Stove breathes better than a typical wood-gas stove, it will fire up a bit more quickly.
    Another advantage of the Siege Stove is that the Cross-Members are higher. Two reasons:
    1) The ample space between the top of the can and the pot makes it easy to add wood without having to remove the pan, and
    2) Smoke from a newly lit fire is not blocked from escaping, and the fire burns better sooner.
    One more point: The efficiency of wood gas stoves is lowered with big wood feeder holes in their sides. Reason: a large volume of incoming air goes straight into the fire rather than up between the walls of the cans. This reduces the gasification effect.

  3. Very Low Cost: For just the cost of a set of cross-members anyone can create a powerful wood-gas stove! Because cans can be had for free (or low cost, if customers purchase them pre-punched from us), the Siege Wood-Gas Stove's cost is incredibly low. Compare this to the much pricier wood-gas stoves on the market.

  4. Superior Ventilation and Ultra-Lightweight: Because the inverted outer can is open underneath and held up by the bottom Universal Cross-Members, air is easily drawn up between the walls of the two cans. Ordinary wood-gas stoves sit directly on the ground and have vent holes around the sides of the bottom to bring in air. Not only does this inhibit air flow, the double bottom adds weight and robs the inside of space for wood fuel.

  5. Improved Support for Pots and Pans: The cross-members widen the support above and below the stove, providing improved stability over other portable wood-gas stoves.

  6. Easy to Build! With the Universal Cross-Members you no longer need to spend a lot of time with specialized power tools to build a wood-gas stove. Until now, DIY wood-gas stove projects have required a lot of work on such tasks as drilling ventilation holes, finding and cutting a circular internal grid floor to elevate the fuel, drilling holes to hold the floor rods, bolting / welding heavy legs onto a canister, etc.

The inner No. 10 can can be used on its own as a wood-burning stove. Or, to make an awesome wood-gas stove, place the gallon paint with the Cross-Members as shown over the No. 10 can, and ergo, you now have a powerful, low cost, and efficient lightweight, wood-gas stove!
The inner can should have a ring of small holes near the top, so that the hot air and gases that are rising between the walls

How to create your own Wood-Gas Stove in three easy steps:

1. Gallon Paint Can outside,
No. 10 (restaurant size can) inside

2. Quart Paint Can outside,
"Progresso" soup can inside

  1. Remove the bottom from the Paint Can with a can opener.

  2. Cut 4 slots in the lip of the paint can for the cross-members. Just saw thru the lowest dip in the lip of the paint can. Leave enough to support the Cross-Members.
    Technique: Use two hacksaw blades in the hacksaw at once. (A 32 tooth per inch blade is best.)

  3. The latest innovation in the Siege Cross-Members are sharpened fangs on one of the bottom members. If you don’t have an ice-pick handy (best), or fillet knife, you can use a 16” X 1” (or thereabouts) branch to hammer a fang into a can to provide air holes; then, when the point is embedded, twist it sideways to enlarge the hole.
    Tip:  Before making holes in the side walls of the can, install the top Cross-Members in the top of the can to help the can hold its shape.

3. No. 10 Can (restaurant size) outside, Big Coffee Can inside.

  1. Inner can: Punch holes in the inner can as in step 3 above.

  2. Outer can:  Begin with the top of the outer can removed.

  3. Cut a circular hole in the center of the floor of the other end using tin snips, heavy-duty scissors or in an emergency, a knife—this tends to dull the knife. The hole should be just slightly smaller than the diameter of the inner can.

4. Big Coffee Can outside,
Chilli Can (40 oz) inside.

Both Quart and Gallon sized paint cans can be used with the Universal Cross-Members to create lightweight single-wall stoves.
