Hi Paul and Colleagues,

Before anyone rushes out to make one, today we set it up beside some "real" bamboo to get enough for a run in my Pioneer Class gasifier, and yes the short comings quickly showed up!

Being thicker and harder walls, the extra force caused the disc blade to slightly move side ways just catching on the edge of the back side plate. My mate and I discussed an alternative side plate design with just a hole in it about 2" (50mm) diameter, so we retain the suspected advantages of the disc blade concept. Another week and you will see it I hope.

I'm aware you would want to take one to a remote place, but your baggage weight would seriously be compromised. Once you have tested one, you might consider just talking key tools like metal hole saws that fit in a pedestal drill, and maybe high tensile bolts so local metal can be worked. If gas cutting is available, then you only need bolts and 1/4" plate steel. You should have some lessons while making your own first, so you can instruct rural tradesmen in the basics. You really need to also test it's ability to be made locally, or at least what support they need to do so.

Doug Williams,
