For those who don't know, regular poster Bob (aka Ajaffa) and his wife recently lost his house and many of their possessions (but apparently not his engines!) to a bush fire. Please see this post for details of an appeal to help him rebuild. Thanks, everyone from LEF.

Here, what is called "steel wool" is hair fine fibers of steel, which actually burn and rust up real easy.
Something from a boat yard called Brass Wool (for scrubbing finish and crud off boats without leaving iron bits to create rust streaks) wouldn't oxidize as fast, but may melt from heat. Maybe stainless wool ? or something like coarse stainless chips & spirals from a machine lathe
Thank gadget,
The pump is a 12 volt solar hot water unit. It is wired to a toggle switch at the starter button.
I will look at the data sheet and check the allowable orientations for the pump.
Ideally the pump and heat exchanger would be mount "off-skid". But this is for testing the concept.
I tried that but he is gone, cleared out, disappeared, maybe the CIA got him. I left him a PM on Microgen, but he hasn't replied or read it. I too found his knowledge useful and easily overlooked his abrasiveness. His insight into everything WMO/WVO is unequalled. If you do happen to go past him, please PM me his details. I know EdDee is also keen to contact him. Thanks, Peter

You can also run it slower and add a thermostat to keep the combustion temperatures high.
You can also load the engine up to 85% of the HP it creates at that lower speed, ensuring that it's adequately loaded and making as much heat as possible.
Good luck with the project, and be sure to post pictures/videos

Shrouding may not be the technically correct term but the 45° seat angle starts at the deck and continues down past the full face of the valve and below it. The head of the valve recessed at .100 below the deck. Certainly not conducive to good flow past the valve,, or great seating either.
