I decided I should get off my lazy fat butt and get to building my engine. It is going to be an .061 bushed to meet the pylon rules here.
I started and almost finished the crank today. This is the rough form, everything is a bit oversize so I can polish and fit after heat treat and grind.
Some details, The journal is .3125 dia with the passage bore at .228, the pin is .137 dia. the counter balance is way thicker than the std Norvel crank and the over all length is shorter than the Norvel. Timing on the widow is 36 deg after BDC and 64deg after TDC the window is .375 long, The edges of the window were left with a .015 flat as per common practice on high reving speed engines (not sharp)
the crank on the right is a Norvel crank for comparison.
