Brief Description:  The gland nut

Placed the flywheel. Red RTV to inner margins. I had a friend who happens to be very, very strong hold leverage against the crank; I have a sturdy angle piece bolted to the prop flange. I then applied my body wgt to a breaker bar at my precisely calculated distance and SHAZAM! The gland nut was properly torqued. What torque value would that be you ask? Sonex says 237 ft/lbs. Tom Wilson says roughly 300 ft/lbs. The AeroVee does not have the particular stress loads at that junction as would an automobile configuration and therefore does not require that much torque. More simply imposes more stress, or so the argument goes. I targeted between 240-245 ft/lbs. This gives me a comfortable margin for error. I'm good with that. The entire thing was anti-climatic.

I used the main overhead support beam in my garage to fix a come-a-long. Using ratchet straps placed in safe locations I hoisted the engine up enough to remove the rotating stand. I then placed the engine on a wooden stand which will allow me to finish assembly. This was simple; after all, this engine does not weigh too much. This is how I will mount it to the aircraft as well.
