worth searching for and acquiring?

Jeff I would use cover technique to pull some twist out. My wing is one piece too
but it turned out great. I have modeled for years and have straightened several
twisted wings by twisting it the opposite way too far then cover and slowly
shrink, let go and see where it goes. You may need to shrink more on the top
side than the bottom. Like Don said the wing is pretty flexible. Mine got stiffer
after the cover but is still flexible.

Don't cut it. Period.
IMO adding a ply scab would introduce stress points on each side of
the scab, but that may not be critical.
You have two good solutions suggested. If the wing is not all
assembled, wetting and stressing may well work. If your wing is all
assembled, Don's suggestion of adding washout would help.
Do you know the status of your other wing; e.g., is it built yet?
Maybe you have the same droop in it, too. Worse would be a loft on
its tip-- a warp in the opposite direction-- permanent bank built in?

My wheels were made and sold by Hayes for airplanes back in the 1920's. Hayes
had about 3 different sizes. They are drop center wheels not the clincher type.
You will notice that there are 3 rows of spokes. The outside row gives them
the strength for the side loads induced by aircraft. I have 300 x16" motorcycle
tires on them. The spokes are straight laced meaning that they don't cross
like a motorcycle wheel does. I am told that because of this I cannot put
disc brakes on it. Others have said the hub would have the ability to spin out
if there was a braking load applied to them. I'm not sure about that and have
not tried it.
A friend of ours had them hanging on the wall above his couch in his living room.
He said we could have them if we would use them. This was back in 1970.
These are the only wheels that have been on this plane. They have worked out
very well for us.

I am about to trammel my wings. Does it make a difference if I use the short or
long turnbuckles? I understand 4" full length for short and 8" full length
for long. If I don't need a lot of adjustment I should prefer the short to save
weight. Correct?

Not much adjustment is needed, John. Some have even gone without the
turnbuckle and twisted the cable 'till tight! Stay with the shorties if you
have a choice.

Uhhh, maybe not.
This matter has been discussed in the past.
The previous BPA newsletters (Buckeye Pietenpol Association) were compiled and
published by Grant McLaren, who holds the copyright to them. Grant has made it
clear that he does not grant permission to copy and/or redistribute the old newsletters,
as is his legal right.
Don't bother asking Doc to make copies.
The only option would be to find someone that has a collection of the old newsletters
that wanted to part with them permanently.
End of story.

Mr. McLaren sounds like a peach of a guy. Glad he is so helpful.
Has anyone discussed with Mr. McLaren the possibility of a group purchase of copies
of the old newsletter? Copyright does protect him, but it doesn't mean he
can't reprint and sell them (again). I would be interested in purchasing for
a reasonable fee. They certainly aren't making him any money sitting in his protective
"vault". Sheesh!
Or maybe I would just print them if I had them and let Mr. McLaren go to the expense
of suing. (Sorry. Just the old Marine in me bristling at the idea of somebody
being "difficult" about a reasonable request)

As I said, this issue has been discussed before.
Questions were asked, and very clear answers were given directly from the holder
of the copyright.
If Grant ever chooses to republish them, I'm sure we'll hear about it.
But for now, the case is closed. Let it rest.
Nuff said.

Bill,
In my very short time associating with Pietenpol builders, I have found 90% (or
more!) of the people to be helpful, giving, and just down right kind. I guess
I am a little surprised when I run into people associated with Pietenpols that
fall far outside those adjectives. Mr. McLaren may be a great guy, and he does
have every right to handle his copyrighted material. It is just a shame to
keep the info locked up and unavailable. I am sure there is a story there that
some new guy like myself would not know. But it is still a shame, nonetheless.
If I offended you with any comments, then I apologize. No intent to offend.

| Subject: | Re: Spar problem |
Jeff,
I have great news! Today I brought down the wing that had the warp in
the
spar, in prep for cover. This trailing edge had warped about =BE=94!! In
review,
before varnish, I supported the wing on the ends, then started spraying
water on the spar. Kiln dried lumber soaks up water quickly! I estimate
that
I used about 1 gallon of water, allowing the =91coats=92 to soak in each
time.
Then, from the strut attach bracket, I suspended about 50 lbs of weight.
In
my case, that was enough to bring it to straight. After drying for a few
days, I removed the weight. The spar remained straight, so I varnished
it.
It hung for about 2 months in the ceiling, during which time I had
little
hope that it would stay fixed. Imagine my relief today!! Best of luck to
you, too=85

the wing is all together... one piece wing
the other side is perfect..
My guess is a trim tab or aileron rigging would work but i don't like it..
i thought about the stress part.. and considered that i could add ply to the rear
side of both rear spars..the full length.. then they would be the same..
i may try the wetting the spar and bracing it in the right position till dry
thanks for the thoughts

Jeff, have you checked whether your center section is square? I have a one
piece wing and had a similar problem with the right rear corner of the wing
sagging. I had used cables to hold the center section in place so I could
easily move the wing fore and aft when I was checking the CG. After saw the
problem with the corner of the wing sagging, I was so focused on the
outboard end of the wings that I hadn't paid any attention to the center
section not being square until my EAA tech counselor pointed it out. When I
squared up the center section, the outboard corner of the wing came up where
it should be. This problem is probably unique to the one-piece wing.

Greg,
As usual, you are the calm voice of reason. I guess we should not worry about 'maybe'
information. Rather, we should enjoy the 'definite' information that is
available to us, such as this forum, westcoastpiet.com, Brodhead, BPA, to name
just a few.
And the great Piet people we meet along the way. Thanks, Greg, for the refocus.
At least for me.
