NACA report 354 gives test results
for aircraft wood. It's results show
that White Ash is superior to Sitka
for aircraft structures. According to
my many comparative tests I
believe they underestimate the
superiority of ash to sitka.
The Sitka Spruce used in these
tests is the highest grade/
highest specific gravity, and
strongest that I've found. Yet
the ash is significantly stronger.
Even the Ash with the sloped
grain was much stronger than
the Sitka spruce.
