Mounted dummy prop hub

I primed the spinner backplate and doubler, then riveted them together:

I had to buy these spacers from Van's for five bucks each, since the dimensions aren't shown on the plans (and I don't have a lathe either).

Using hardware-store bolts, I attached the spinner backplate to the dummy prop hub. The plans call for an AN960-416 here, but I think they must have meant -616 for a 3/8" bolt.

Another view:

Then I bolted the backplate and hub to the engine crankshaft. There's only enough clearance to turn the captive prop bolts about one flat at a time, so this part took a little while. Removing the prop to replace the alternator belt is going to be annoying.

I plugged the oil passage to keep moisture out of the inside of the crankshaft. The hole isn't threaded, but I managed to find a plug that fits somewhat snugly and used fuel lube to seal it.

Just for grins, I threw the top cowl on there just to see how it looks. Pretty cool:

Oh wait, I forgot about this part… I may need to finish the top skin before I can work on the upper cowl attachment stuff. Argh.

Back to wiring I guess…
