This is the Prop Hub made
for my corvair engine by Dan Woodward of Knight
Hawke Experimental Aircraft in Epsom, NH. Dan makes prop hubs for
VW and Subaru conversions. When I came home from the 1999 Gathering with
William Wynne's Conversion Manual.
I asked Dan if he could make me a hub for the Corvair engine. He took
a look at William's drawings included with the manual.

He said he would come up with
something. This is the result. A hub with a third step to mount the flywheel
on the hub without the need to make a puck to keep the flywheel and hub
strait. The flywheel is one of Dan's universal ones. The ring gear is
from a Subaru mated to an aluminum web that Dan machines. Most are used
for a pre-rotator for Gyroplanes.

The bell housing is cut down
to make the front cover on the engine. A 3/8" plate is used to mount
the '85-'89 Subaru Starter
The top cover is made from 1/4" aluminum plate. Grade 8 cap screws
3/8-24 mount the hub to the flywheel flange of the crankshaft. The crank
was drilled and tapped for the cap screws and a 1"-14 safety shaft.
The safety shaft was made out of 1" x .188 wall 4130 steel tubing.
