I wanted to see how small I could make a Gasifer  So I started off with a simple can in a can ontop of a can

This was the original design braze welded together. The idea is that the gases would pre heat any  fuel and cool down a bit in the process.

This would have worked well in theory but there was a problem with the construction.

The spacing between the cans was not enough to capture the gasses I wanted.
So here is Version 2.0 made slightly bigger and more reliable

Much bigger burning chamber and better ash control.Welded solid with my flux wire welder :)
