OK, how come I haven't seen this classic on
a Piet yet??? Even the tail's the same shape.

Jeff, I have absolutely no experience with a one-piece wing, but just
yesterday (Feb 17) a couple of friends and I put my 3 wing pieces together
for the first time. Had a little trouble getting the holes in the metal
pieces to line up but after we finally got things together the wing looks
OK. Picture attached. I used spruce spars, incidentally.

John, I purchased my turnbuckles from a person (rather than pay full price
for new ones) and they are sort of hybrid. The barrels and forks are from
short ones and the pin eyes are from long ones. They look kinda funny, but
they work fine. I doubt the weight difference between short pin eyes and
long pin eyes is noticeable. C

| Subject: | Brodhead Pietenpol Assc newsletters |
Everything said about the desire of the copyright holder to not make the old
BPA back issues available is true, so that is a moot point for now.
However, IF you ever hear of anybody selling their collection. SNAP 'EM
UP!!!
I was lucky enough to be about 20 years worth with my project with the first
ones from the very early eighties. They are not only an invaluable resource
for a builder, but they are very interesting reading.
The flavor was very technical and flying oriented with TONS of useful info
and stories, good and bad, to learn from. Grant had a soft spot for Fords
so the newsletter heavily promoted the "purist of the pure" Piets.
Cool stories like props flying off in flight, photos of the twin towers from
a Piet! (try that today.) daily logs of California to Brodhead trips with
lots of forced landings on desert roads, bailing wire fixes, sleeping bags
under wings, filling radiators from cattle ponds, Marvel Mystery oil, flying
for four days on two sandwiches and tractor parts/bubble gum fixes.
There was one year with something like 37 Piets at Brodhead.
They seemed to be VERY productive decades seeing lots of Piets getting built
AND finished AND flown.

Maybe just maybe the holder of the copyrights will realize a lot of new Pietenpol
Builders (like me) are around who would greatly appreciate and benefit from
reprints or allowing someone to compile articles and publish them
I for one would be very grateful. Maybe?????
If anyone has back issues they would be willing to sell I am interested.

| Subject: | Re: Brodhead Pietenpol Assc newsletters |
Birth of the Pietenpol Association
This is my recollection if someone can update the timing more accurately please
do so.
NATIONAL PIETENPOL ASSOCIATION newsletter by Janet Green in 1977 which then became
the INTERNATIONAL PIETENPOL ASSOCIATION in 1985 with the newsletter produced
by Bob Taylor.
The BUCKEYE PIETENPOL ASSOCIATION first appeared in 1983 and the newsletter was
produced by Frank Pavliga (Dick Akire was president) and was later produced by
Grant Maclaren in 1990. In 2001, the Independent Register of Brodhead, WI started
producing the BPA newsletter and the first color copies were made. Then
around 2005, Doc Mosher assumed the responsibility for the BPA newsletter until
the present.
This is the closest I could figure from my archive of newsletters.

| Subject: | The previous pietenpol club |
Several of us have newsletters going back to pre-Pavliga days. Grant MacClaren's
are by far some of the most professional and informative of any of the eras.
Grant shows up at Brodhead sometimes and largely remains in the background. We
tried to twist his arm to continue publishing but other interests and life's
changes had him going in another direction.
Several years ago I sent my entire collection to someone who was going to compile
the whole history and make it available to anyone who wanted it. After keeping
my newsletters for a year or so, I got them back but nothing more was ever
said about his project.
I suspect that even if they were made available they would be used about as frequently
as the archives on this website and the same questions would still be
asked with the same regularity as always.

| Subject: | spar problem-again |
Jeff,
It sounds as though Gary has a de-warp fix for a fully assembled wing,
referenced below.
However if you do not want to try that, I don't think your original
idea of scabbing
on a short length of ply will be detrimental. Consider that we
introduce a major stress
point where we scab on ply at the lift strut attach point. We can
mitigate the differential
loading by sanding the ends of that ply (like one half of half a
scarfing process, right?)
to taper off the forces at play. Do the same thing here. Make sure
the ply length is long
enough to straighten it out.
And, after all, the ply scab is the FAA-recommended treatment for a
cracked spar, etc.
Lastly the Piet spar design is very forgiving and already overbuilt.

Subject: RE: Pietenpol-List: 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

In Chet Peeks Pietenpol book Chet states that BH Pietenpol had this tubing custom
made. Another place, maybe this forum, I read that the company that made it
is still in business, but no longer supplies it.
What is the true story on this tubing?
Did it have a name?
Does anyone know what it weighed per foot?

thanks for the thought..
Exactly my thought on the crack repair per 43-13..
it if OK for a crack repair how much stress are we causing ?
I'm going to level the plane and check the whole thing..struts..cabane struts...and
braces to make sure something isn't out of wack.
i'm trying not to loose too much sleep yet..
covered my elevators and rudder today.. and will stitch em tomorrow..
but the next step is leveling and measuring

That tubing has not been available for decades upon decades, probably
disappearing not long after Pietenpol included it in the plans.
Nowadays you use normal streamline tubing and install jury struts.

Thanks Ryan, I know what we do today. I'm asking about the HISTORICAL aspect of
this specific brand of streamlined tubing.
This is what I need to know:
What is the true story on this tubing? Was made custom for BHP or was it an off
the shelf item? What period of time was it available?
Did it have a name?
What did it weigh per foot?

| Subject: | Re: Question Re: Flying Strut Attachment Location |
Hey all,
I have a question regarding the location of attachment of the flying strut. I
am building the three piece wing and am using 3/4" solid spars. Each half of
the wing (not including the center section) is 13' 2.5" per plans. Today I laid
out the spars and slid the ribs into position.
As I read the plans, the center hole for the flying strut strap attachment to the
spars is 79" from the root of the wing half. With my ribs in place, I measured
this distance from the root of the wing. This location (79") appears to
be only 3/4" from the next (outer) rib. This doesn't seem to be correct as it
doesn't leave room for the underlying ply or the 3/4" square compression struts
that would be fit in place.
I did review westcoast piet pictures as well as some of the other personal build
sites (Textor, Markle, Chouinard) to see how others have done it, and none of
the pictures I saw have the "spacing" problem I seem to be running into.
I spaced my ribs according to Drawing No. 5 of the "Improved" plans (from the outer
edge, 4.5, 12, 12.5, 12.5, 12.5, 12.5, 12", etc., moving towards the root).
Moving the "offending" rib doesn't seem to be the answer as it will change
the aileron length.
Did anyone else run into this problem? Or did I space my ribs incorrectly?
Any advice would be appreciated.
Thanks,
Tom
