Lynn, What do you think of this stuff for bearings in a rotary? Side plate surfaces? http://machinedesign.com/ContentItem/72386/TheBondedOnBearing.aspx

Here's some real world tests:

I hope to be applying a coat to my side housings tomorrow. Just hoping the weather cooperates. I spent last weekend getting my 'oven' working. It consist of a wooden box that is doubling as a blast cabinet. For the oven function, I remove the hoses, replace the top with an inuslated one (house fiberglass batting held with aluminum foil), and add a board that has four halogen bulbs supported by paperclips. It's a Junk-Yard Wars contraption, but it only has to work once.
I've already coated my rotors in a thermal barrier. Used a toaster oven for the baking. I've removed the exhaust inserts from the rotor housings, and I'll coat them with thermal barrier before putting them back. The oil chain sprockets and the distributor drive gear will get a DFL (dry-film lubricant) coating. I'm still debating if I want to coat the rotor and main bearings.
The first test of whether it is all worthwhile will be to put a torque wrench on the engine without plugs or exhaust and see what it takes to spin it. Energy not needed to turn the engine will be delivered to the prop, or lighten the load on the starter.
