Properties of a good wood gasifier

Thanks for that. I learned something today. Now I see why Tone showed us a picture of his masonry bits.
Anyway, this is a piece of an axle shaft from a 1998 Bronco. I heated it orange and then let it cool slowly in an old coffee can surrounded by charcoal with the lid on so the charcoal wouldn’t burn up. It is soft. I can use regular metal cutting tools on it.
