Woodgas Can Stove

Step 3 Drill the bottom sides of the inner can

This step I will be doing differently in the next model.

What I did here was drill two rows of 1/4" holes in the bottom side walls of the can. This does not provide enough draft. A design known to work, this stove's closest relative in fact, has holes in the bottom, rather than the bottom sides, so one could drill out a bunch of quarter-inch holes into the bottom.

I intend to drill out another can in the near future, with three rows of 3/8" holes up the inner walls, and perhaps more holes as well. I'll update this instructable accordingly, and welcome comments on people's luck with this step.

The penny-wood stove (http://www.csun.edu/~mjurey/pennywood.html) uses a grid of much smaller holes all across the bottom and one optional ring around the outside. The lower they are, the longer/better each charge of wood will produce wood-gas, so on the bottom is probably the best location.

Ideal might be several big openings on the bottom and a wire mesh bottom dropped into the bottom of the can to spread out the ventilation manifold.
