Group,
We finally had our first big snow storm of the year... Here in Utah we usually
have more snow by now but Mother Nature hasn't been kind to us skiers.
How this thread is Pietenpol related is... this is the road which I drive out to
my hangar at the Skypark airport to work on the Piet, I am glad I wasn't one
of the poor unfortunates to get piled up. Hope you enjoy the video.

Ive made several changes to Fat Bottom Girl over the last several months and have
promised updates. Here they are:
Wood Struts
The original wood struts have Douglas Fir tops and bottoms sandwiching aircraft
plywood. I bought them from a friend. I noticed signs of delamination between
the fir and the plywood on all the struts at around the 250 hour mark. The
worst delamination was on the left rear strut, which I used as a support point
for loading passengers. Im pretty sure the guy who built the struts used T-88
but I dont remember. Anyway, a dear friend who shall, as always, remain nameless
(Gary Boothe) made new struts for me. They are constructed from four
hickory sticks laminated together. The glue lines on the original struts ran
parallel to the wing, the new laminations are perpendicular. They seem quite
stout though I have not flown them very long. Gary is a saint.
Note: For what its worth, the holes on the old struts showed no sign of distress
or elongation. Thats with 260 hours, several hundred takeoffs and landings,
and a significant wing dragging episode on each side.
Wing Cross Wires
I used the cross wires at the right front cockpit to hold the wing in place. I
can honestly say that I do not remember why. I also do not remember why on earth
I lopped off the ears from the top motor mount where the diagonal cabanes
would mount. Regardless, I added diagonal cabanes and got rid of the wires to
improve ingress/egress from the front cockpit.
I did not want to cut a bunch of fabric and remake motor mounts, so I carefully
crafted an East Texas Redneck Modification (ETRM) to provide the front mount
for the diagonals. I welded them to the vertical cabanes at the top. Ill improve
that ETRM when we re-cover the plane. See attached photo.
Clourcars Prop
Ive taken so much abuse for the ugly-but-effective Warp Drive prop that I broke
down and bought a wooden prop from Cloudcars. It is 68x34. They originally
sent me a 68X27 which Jay calculated to be similar in pitch to my Warp at 7.5
degrees. It wasnt enough pitch. They very kindly provided another propeller.
It appears to have a little more functional pitch than the Warp. The plane
climbs a little slower, but still at better than 500 fpm, and flies about 10%
faster. Since were not allowed to fly our Cloudcars in the rain I may switch
to the Warp for traveling to and from Brodhead, and then use the pretty wooden
prop while there. See attached photo.
Landing Gear Springs
I think Ive talked about this already. I re-did the gear with springs instead
of bungees after one of the bungees failed and left me limping down the taxiway
at an awkward angle. I used Hans Van der Voorts drawings.
The Dreaded Corvair
The Weseman 5th bearing has been installed for ~60 hours. So far so good.
Last year at this time I noticed a sudden drop in power of about 150 rpm. It turned
out to be a burned valve. Roy Szarafinski re-did the heads for me. The
reworked heads actually give me an increase in static of 150 rpm. I originally
had the heads done at a car shop several years ago. Its safe to say that Roy
does significantly more sophisticated work than most car shops.
Use as you see fit.

| Subject: | Wing Strut Forks |
Can anyone help on where I can find the minimum thread engagement on the
forks that fit in the end of the wing struts? I'm getting ready to cut
the struts to the correct length and would like to assure I can use the
maximum amount of threads for adjustment and still have sufficient
thread engagement. I can't find anything in the Bingelis books on this.
The forks I have are from Aircraft Spruce - 7/16 x 20 threads and the
threads are 2 1/4 in. long. The barrel it fits in is about 2 in long as
well. Should I assume 1 in. minimum thread engagement, then have 5/8
in. adjustment either way, or ??????
Appreciate any help.

That was a very good post Kevin. What kind of degree setting did you have on
your warp drive. Also what was your static and cruise speed? I would like a
cloudcars too but I need to get my plane flying first. I am about finished with
the first wing. A good way to carry the prop would be tied onto your wing struts
just out board the jury struts. You will never know it's there. Cheers, Gardiner

Hi Kevin,
What a beautiful prop; glad to hear it improves your cruise and that you still
have good climb. I like the forward cabane struts to the motor mount; I have those
just mocked up right now; was going to wait until I do weight and balance
first time.
You have been busy and your Piet is even better looking now.
Cheers,
Jim B.

| Subject: | Rudder Pedals VS Rudder Bar |
I know some Pietenpols have rudder pedals for the rear cockpit and some have a
rudder bar.
For those that may have flown both types is there a difference in handling on the
ground or in the air?I would think not in the air so much as ground handling....maybe.
Thanks
Larry

Larry,
Rule of thumb diameter = minimum thread engagement.
Thus 7/16 diameter you need 7/16 lenght to get full strenght on threads.
But more is always better.

Subject: Pietenpol-List: Wing Strut Forks
Can anyone help on where I can find the minimum thread engagement on the fo
rks that fit in the end of the wing struts? I'm getting ready to cut the s
truts to the correct length and would like to assure I can use the maximum
amount of threads for adjustment and still have sufficient thread engagemen
t. I can't find anything in the Bingelis books on this.
The forks I have are from Aircraft Spruce - 7/16 x 20 threads and the threa
ds are 2 1/4 in. long. The barrel it fits in is about 2 in long as well.
Should I assume 1 in. minimum thread engagement, then have 5/8 in. adjustme
nt either way, or ??????
Appreciate any help.

| Subject: | Re: Rudder Pedals vs Rudder Bar |
My Piet has a rudder bar in the back and pedals up front, and I fly it from both
seats.
I like the bar a lot better and I was extremely skeptical about it when I first
sat in a Piet.
I think it's a matter of geometry. Since the pedal is a class two lever and the
linkage attach point moves in an arc, it's not a linear thing... and in the
wrong direction (most sensitive near neutral and less sensitive as travel progresses).
Pedal hookups for rear seat usage may be different though.
