[Stoves] Magh Utham Woodgas Burner

[Ronald Hongsermeier]

Dear Crispin,

thanks for the pic!

One observation and one suggestion:

I can't tell by the size of any referents in the picture how big the can is.

By putting an extra "half-round" in the slit on one or several of the slits, it would be possible to add fuel through the sides and thus bring the cooking vessel into constant distance from the top of the exhaust.

regards,

Ron H
