Finished my current project, Vederstein's Camgine. OK, now what? Well why don't you finish your 1/4 scale Rider Ericsson Hot Air that's been on the shelf for a few years. OK, all buttoned up. The only thing I deviated from was changing the displacer unit from steel to grill brick to make it lighter. Put a flame under it and no go. Yes, the unit is rather tight. So, my question is, how free should the unit be when spinning the flywheel by hand? I still have to free up one connection. When spinning this unit by hand, how many revolutions do you think it should spin before it stops with no heat? Any help would be appreciated.
