? Could you use some type of basket or holder to use saw dust in a RMH
in the RMH I built I used a 1/2"mesh SS basket to hold wood chips fed from a hopper, works OK but still tweaking it. (wood chips free by the truck load from local tree trimmers)
Len: I'm in So Cal spring and summers here dry a large truck load of chip pretty fast, turn it a couple of times with tractor during the dry season. I started getting the chips for the garden walk ways and have a pile 2years old (rather large pile) so when I started playing with the RMH it was an obvious fuel.

I would do an iron plate and pipe with a hydraulic jack myself then i could put a few thousand pounds of pressure on the briquette. also you might think about the dura log type briquette as it may work better than what we where working with. (the ones with the hole in them.) make the briquette either small or to the height of the feed tube.

Version 1.3 tested tonight.
Added a bit of kerosene to the slightly damp saw dust
added two more burn holes in the sawdust charge
added a red hot secondary burn plate raised 1/2" off the top of the 35 g dust charge dum where the plate had a down turned edge to trurn the flame down easier while being aided w by burnulli flow from 50g drum lid & plenum pressure between lid and burn plate
at that level the 50g drum got cherry red and no smoke was visible arround the cowled 50g barrel of water to be boiled.
then there were some problems that reduced the burn rate.
