Subject: | UV exposure, realiy ck... |
After years of reading about UV degradation, exposure issues with covering
materials; and seeing UV tests galore I got to thinking to myself. "how many
hours of sunlight exposure will most Piets actually experience?"
I'm sure they exist, but I don't know of a single Piet that doesn't reside
full-time in a hangar. I then did some math and calculated the number of
hours a year she's actually outside, and what percentage of those days are
full sun, and what percentage of full-sun days eve/morning flights with a
low sun angle to arrive at some numbers.
I'm certainly not suggesting UV protection is unimportant. I'm just
wondering if we are possibly overdoing it sometimes considering the real
world application on this airplane.
Do some figuring, I'll bet you'll be surprised. I was. I think I concluded
that I could fly with untreated ceconite for like two decades.

I appreciate this post, and it's great that someone would buy the engines to save
them for us. I have an engine just about apart, and a spare for parts. Good
to know that other engines/parts are out there. Thanks for the information.

I found a guy in Colorado that has at least 6 cores and set me up with what I think
is a great build. He's been rebuilding corvairs for 30 years and has lots
of stuff. Let me know if you need his contact info. Found him on Boulder Colorado
Craigslist.

I was talking to Rick at antique engine rebuilding and he tells me he has never
