Good points all.

The point that stood out most for me was the part about the crank
from the engine that William built for his own demo 601. From the
article: "This engine represents a standard installation, albeit one
that was flown at its limits by Gus"... "showed stress fractures on
both sides of the area in question." at 200 hours. "no nitride"

Yes, that paragraph does seem to run contrary to the rest of the
_long_ website's information. So what gives, others in the know?

His recomendation of nitriding every corvair crank is NEW based on this
data and the several KR crank issues in the recent past. In other words,
nitriding was considered optional until the last week or so....
