It's about time there was a Corvair College somewhere in the Midwest!
Although I did have my wife convinced that I would have to go to Florida for
this. :)
Kip, I am very interested and give 50/50 odds of attending, the only thing
holding me up is finding an appropriate core and scheduling the time away
from my wife and my two boys. Please put me on your list.

Kip,
I am interested, and definitely might show up.
Skip, in Atlanta now but hope to be in West Virginia next summer.

Knowing that today was the big 100th aniversary day and that the weather was
beautiful at 7:00am, I called my FBO early to get on the board for this
morning. My concern was that all the other airplane nuts in the area would
snatch up all the rentals. Apartently, this was not the case. I had my
choice. On the other side of the airport is five or six rows of T-hangers
and only one Quickie was getting ready. I couldn't quite understand, I
guess there are less airplane nuts than I thought.
So at about 9:00CST I went flying. Gorgeous clear cold morning and just
about had the pattern to myself. The Quickie behind me on a call to tower
thanked Orvile and Wilbur for the privelage, the tower responded that he
would pass along the message. One trip over to my hometown airport for a
T&G, two if you count the missed approach (I've got to practice landing in
strong crosswinds). Back up, some easy flying, and then back into the
pattern at Carbondale. I landed about 9:40 (or 10:40EST) roughly about the
same time they did, only 100 years later.

| Subject: | Corvair questions |
--> Pietenpol-List message posted by: hickpiper@misn.com
Greetings all,
I am going to pick up some Corvair engines this weekend, (my Christmas present!)
and after checking the #s I found that one is a pre '65, and I don't recall
the exact hp, but it is less than 110 hp. Will this have any parts usable on the
110? I'm sure something on this subject is archived , but so far all I could
find was the difference in cranks (pre 65's are weaker?) and bore size. I am
also wondering if I need to get some sort of bell housing...seems like I remember
reading something about needing one for something, but I don't recall the
specifics. I do plan on getting William's conversion manual, but I stumbled onto
these engines and want to nab 'em before they're gone! Thanks in advance...
Jon Jones in southeast Missouri...still trying to save up for plans & spruce without
upsetting the wife too much.

What do you mean when you say "some Corvair engines"? Like there might be
more than one???? Hey, if you mean there may be more than one usable setup,
let me know.
I might want to drive up to SE Missouri with a bunch of spare spruce and
Pietenpol metal fittings I have sitting here and trade it for some usable
corvair stuff...(?)
Just a thought.
Jim in Plano.......always anxious to help someone (well, ME in particular)
avoid upsetting the wife too much.......

Eric,
First the disclaimer: I'm not a structural engineer, and I haven't run the
numbers for the Piet fuselage. I do understand a lot of the physics
involved. I built my Piet fuselage 1 inch spruce longerons.
You're calculations are correct, at least for tensile strength. Stiffness
depends on dimension squared, and goes down even faster. There's a MIL-SPEC
on spruce--I don't have the number handy, but someone on the list probably
does. It lists substitution recommendations for other woods, including
Douglas fir.
On the other hand, there seems to be a general consensus that the Piet is
overbuilt. You could check into the construction used for other wood planes
to get a feeling for what is done. The only data point I (think) I remember
is that I've seen an Ospery I amphibian that appeared to be built of 3/4
inch fir.
Doublers seem like an interesting idea. If I were going to do it that way,
I'd think about 8 long strips on the outsides of the corners, over the
gussets, with filler blocks between the gussets. 1/8 inch Douglas fir over
1/8 inch filler would probably bring your strength back to nominal.
Stiffness would (probably) be better than using 1" spruce. I'd worry a bit
about using a spruce doubler over Douglas Fir because of a difference in
stiffness (Young's modulus to be specific).
Let us know how you decide to go.

Subject: Pietenpol-List: Good Fuselage??
--> Pietenpol-List message posted by: "Eric Williams" <ewilliams805@msn.com>
Hi everyone. This is my first posting to this list (although Ive been
lurking for a while) and I have a situation that I would really appreciate
any comments or suggestions on.
While at Oshkosh this year, a very good friend of mine, who has too many
airplanes in various stages of repair, offered to give me a Piet project
that he had acquired several years ago from a friend of his (the builder).
I picked up the project this past weekend and it consists of a completed
fuselage structure with the plywood skin on the forward half and the floor,
a complete set of wing ribs, and a complete set of tail surfaces.
The workmanship on the project looks to be acceptable however, one thing
that bothered me was the longerons and the other fuselage members appeared
to be small in cross-section. The builder happened to stop by while we were
loading it all onto my trailer. He said that he had used douglas fir and
since his research proved to him that fir was 25% stronger than spruce, he
had reduced the dimensions of the members by 25% (from 1" to 3/4"). The
problem with this line of thinking, as I see it, is that when you multiply
3/4" by 3/4" you end up with 0.56 square inches as the cross-sectional area
of the wood that was used, as compared to 1.00 square inch in a 1" x 1"
member. That means the longerons in my fuselage actually contain 44% less
material than had they been built using 1x1 stock.
I would sincerely appreciate any thoughts you all might have as to the
usability of this fuselage. I should say that it "feels" strong and I did
sit in it while it was supported at the approximate landing gear points and
there appeared to be no deflection or creaking at all (there were a few
engine noises made however). I also wonder if I might be able to epoxy some
1/4" strips to the various members for added strength? The builder said he
had used West System epoxy to construct it.
Thanks for your input.
