| Subject: | Turnbuckles and hardwire |
Hello
I am working on the wing of my pietenpol and was wondering if anyone could tell
me where to find the cross reference for 325 sf turnbuckles. Also the plans
call for hardwire. I cannot seem to find this,and was wondering what size cable
to use.
Thanks

| Subject: | Regional Pietenpol fly in at Barnwell |
Fellow Piet builders and flyers,
Several weeks back, I posted a notice here about having a "regional"
Piet fly in along with Corvair College #21 that will be held on
November 11, 12 & 13 at Barnwell airport [ KBNL ]
So far, no flying Piets have indicated they would attend. Some who
normally would come have scheduling conflicts. There are about 8-10
builders to date who have indicated they will be here and want
information on how to build their Piets.
We will have my flying Piet, a static display of Don Harpers Piet on
the gear with corvair engine, maybe a second static Piet fuselage with
tail feathers, and we will hold a Brodhead forum type question/answer
session in my hangar to discuss building tips, do's and don'ts. I'll
have a rib jig and materials avaliable for those who want to learn how
to build a rib.
any questions/comments, let me know

Like Gardiner, I plan for 6 GPH. My stock wing tank is too small. I'd like another
3-4 gallons, which I'll add, somehow, eventually.
I'm really itching to get out after 90 minutes, and I'm relatively young and spry
(& Don Emch is younger and spryer than I).
If you live someplace with long legs between fuel stops I understand the desire
for lots of gas. If you don't, you may not need all that extra weight.

Hi Tom - I made a "hole" in the wing center section with fabric glued around and
down into the edge of the hole. The tank fits in the hole, is held down with
straps, and has an aluminum cover screwed on around the periphery, much like
what's already been described.
Notes:
- If you go this route, the edges of the hole need to be really stout. I made
a very robust wood structure on which to glue the fabric and still managed to
pull the structure apart when tightening the fabric. The fabric is astonishingly
powerful when it tightens up. I had to cut the fabric, re-do the wood structure
around the hole, and then repair the fabric. You don't really see it unless
you look, but it was all a pain in the butt and very traumatic when the
structure broke loose. I think I said something like, "shoot!"
- Not sure why you'd need to ground the aluminum cover.
- I've had the tank out once for inspection and for repair of a pinhole leak.
I was glad I made the tank easily removable.

I just had an unexpected windfall. A gentleman that I know came by my
office and said that since he knew I was building a Pietenpol Air Camper,
I might be interrested in this. It is a photocopy of a letter from
Bernard P. in answer to some questions concerning his use of the Corvair
engine. I do not know what the original questions were or who the letter
was addressed to but still - - words from the master himself.

I made my tank from aluminum. It fits between the spars and the ribs. It holds
16 gallons. A cross section of it is the same as the ribs. The top extends past
the tank to mount it to some strips I put on top of the spars. It will just
ride on the ribs with rubber between. I am not real happy with the tank because
it warped up from welding pretty bad. I am going to try to fix it but may build
another one.

I think you'll find that all the cable in the Air Camper is 3/32 except for the
control stick to bell-crank (which is 1/8) and possibly the straight-axle landing
gear support cables. This assumes you substitute the 14-gage hardwire with
3/32 cable on the tail.

Graham,
Helpful info. Thanks for sharing.
Here's a helpful website that lists gas stations that still offer ethanol-free
gasoline. The website gets updated regularly, by its users.
http://pure-gas.org/
Just click on your province or state, and get a list of stations that still offer
ethanol-free gas. Click on each specific station for details.
In Canada, for the most part, Shell is the only large retailer that still offers
ethanol-free gas - and then only the high-grade (91 octane) fuel. Regular has
10% ethanol, and mid-grade is a blend of regular and high, so it has about 5%.
However, just going to a Shell station isn't always a guarantee that the high
grade is ethanol-free. The pumps that are ethanol-free will have stickers on
them that state that the 91 octane is ethanol-free. Probably best to do a test
of the actual fuel at each purchase to make sure that it is truly ethanol-free.

Hello all,
Just wanted to introduce myself to the list and apologize in advance for all
the stupid questions I may ask in the future.
Bryan Reed from Buckeye, AZ
I have Piet plans on order and am awaiting their arrival. I will be building with
my great friend Dennis Mclain. You may know him here as he is the cartoonist
on the weekly Barnstormers email list.
I am 51 so I am old enough to know how little I know. : )
Flying for about 20-years: 5 in sailplanes, 10 in ultralights and the last 5 as
a Cessna driver.
I am a structural engineer at a wood truss manufacturing plant and yes it is slow.
I also am a residential general contractor as well as a general pool building
contractor. I spent many years as a carpenter so have pretty good wood skills.
My build partner has the metal skills and is actually an artist and graduate
from LA School of Art.
At this stage in my life the above are only what I have to do to afford to fly
as that is my passion.
Thoughts (right or wrong) are:
Build per plans
Long fuselage
Continental-65 (May add port and polish w/Higher compression pistons)
No engine electrical-hand prop and wind generator w/battery to run radio and transponder.
Per plan split gear
16 to 18" Motorcycle wheels.
Sitka Spruce w/Glue T-88 ???? (Kinda firm on the Spruce though)
Well that is what my thoughts are anyway,
Any and all advice/criticism greatly appreciated and thank you,
Bryan

Jim, my center section is 36 in wide and holds 20.5 gallons. No fabric on CS.
All plywood with an aluminum cover screwed down. Just finished 30 ribs,--One
extra and one for a wall decoration. Also just finished rewiring the whole plane
with a new panel and lots of help from my electronics guru. New tail feathers
have hinges on now and covering is next. Also I have to make new cabanes as the
old ones were smushed. I have the materiel for cabanes but haven' decided
whether
to use aluminum from carlsons for the struts or to build wood ones out of
douglas fir. It is just like building a new plane again only this time I have
all the metal and fittings made. STILL.
Thanks for the interest, and I know that this plane will be better than the
original I think I will name it the REPIET. Cheers, Gardiner

Sounds like you are off to a good start. You have lots of options, but
if you use a hand prop
A-65 without an engine driven generator you don't need a transponder, so
you can skip the wind
driven generator and battery. I just use an i-com handheld radio with a
headset and it goes over 10
hours between charges.
Welcome to the list, this is a great group for getting more than one
good answer to every question.

Thanks Ben,
Hoping I was headed in the right direction.
While transponder isn't required with non electrical it is very busy here. It
is a good safety item to have a transponder as most airports around town are
towered. Without it we are not very welcome and that can be shown in some "not"
very subtle ways. I also transition Phx Class-B a lot and it is required there.
I like the Icom radio and may use one but they can come across as very weak
to towers and other planes. I'm not sure why as I have tried them with various
antennas. Have access to a couple of old Delcom portables. They were always
better when meshing with conventional radios so I may give them a try.
Sometimes I wish it wasn't so busy air traffic wise as I am just looking to get
north to the mountains so I can noodle around at a couple hundred ft agl.
I like more than one good answer, it keeps you on your toes.
Thanks again,
Bryan

Welcome, Bryan!
I like all your choices. Pretty much what I did although I have a straight
axle. If I had it to do over, I would do the split axle gear with wire
wheels, like Don Emch and Kevin Purtee did.
Only possible change I might suggest would be to do without the wind-driven
generator. My only experience with one of them (on a friend's Luscombe that
I was ferrying) was not pleasant.
On mine, I have full comm radio (not a hand-held) and a mode C transponder.
I run them off a battery that I recharge every few flights on the ground.
As long as you don't have to run the transponder all the time I can get
about 20 hours of flight between charges.
You will find this group to be the very best group on the internet. Full of
good advice and friendly (until you abuse said good advice).
Plan now to come to Brodhead next July and bring a camera, tape measure and
notepad.

Jack,
I am sensing that the wind driven generator is a bad idea. I have has several
emails offline advising the same. Out with that idea.
My first thought was a marine battery and just plug into a good battery tender
when not flying. A "friend" had suggested the generator.
Where did you mount the the radio and transponder? I would like to put in the
Val Avionics Com 2000 as I can get a deal on it but am unsure of which transponder.
Any suggestions?
Thank you,
Bryan

Bryan,
I like your way of thinking! I'm probably a little biased though. With the exception
of any radio equipment, your ideas are pretty much how I built mine.
T-88 and all. Here is a shot of it from this past weekend when my dad and I flew
out to breakfast. He was in our Chief and my son and me in my Piet.

Bryan,
I mounted my radio and transponder in the centersection, because most
avionics are 12" deep and the space between the rear instrument panel and
the back of the front seat is only about 7". By putting them in the
centersection they are easily accessible in flight, but don't interfere with
the "antique look" of the airplane. Here's a photo showing what the
installation looks like:

Jack,
I am sensing that the wind driven generator is a bad idea. I have has
several emails offline advising the same. Out with that idea.
My first thought was a marine battery and just plug into a good battery
tender when not flying. A "friend" had suggested the generator.
Where did you mount the the radio and transponder? I would like to put in
the Val Avionics Com 2000 as I can get a deal on it but am unsure of which
transponder. Any suggestions?
Thank you,
Bryan

Subject: Pietenpol-List: Fuselage tank and the C-85 engine...and beware
ethanol in auto fuel.
Group,
I will deal with the tank question first, and then provide a "heads up" with
an account of my experience with ethanol in auto fuel.
My Pietenpol has a 12.5 Imp. gal. ( 15 US gal.) fuselage tank located in the
nose. It is an expanded cross section of a Piper J3 tank, forming an ellipse
which holds 3 US gallons more than the J3's 12 US gal. This tank provides
ample clearance for the feet of the person in the front pit because it is
mounted as high as the cowl behind the firewall will allow.
Initially I used a Continental A-65, but substituted a C-85 early on and,
although I was apprehensive about the C-85's increased fuel flow
requirement, there has never been a fuel feed problem in over 700 hours with
the C-85.
However, totally unrelated to the fuel tank location, I did have a fuel flow
problem caused by ethanol (5 to 6%) in the auto fuel I was using in my
Pietenpol. For years, since 80/87 aviation fuel disappeared, I have used
regular auto fuel without problems until this summer. I had long ago
substituted steel float needles, in my Stromberg NAS3 carburetors, for the
neoprene-tipped ones but, for some reason as yet undetermined, didn't
realise the carburetor in my Piet still had the neoprene-tipped one until I
had disassembled the unit. I installed a spare carburetor that I KNEW had
the steel needle and, of course, it is unaffected by the ethanol in the
fuel and works fine.
Since then I measured and recorded dry dimensions of a new (old stock)
neoprene-tipped needle and then placed it in a glass jar containing
fresh-from-the-pump auto fuel. After about 5 hours I re-measured this needle
and found it had "grown" appreciably. This would lower the fuel level in the
float chamber causing a lean mixture which, at full throttle, could (and
did) result in engine stoppage. I strongly recommend that anyone using auto
fuel make certain that a steel float needle is installed in the NAS3 series
carburetor, if they have one on their engine. The Delrin needle is an
alternative to the neoprene type, but I don't know whether it is affected by
ethanol, or not. Someone out there will know.
I had flown for about 30 minutes with no problems, landed, and then
attempted to take off again. It was a short flight. Luckily there was lots
of runway ahead since I barely got airborne when things abruptly became
quiet. The first thing I checked was the fuel flow to the carburetor and it
was ample. The problem had to be in the carburetor...and it was. Why this
didn't occur at the first takeoff perhaps could be explained by these
factors:
1. The oil was then cool and the engine didn't turn up to the critical rpm
during the initial takeoff.
2. I had recently installed a finer-pitched propeller, allowing the engine
to rev up higher than it did with the other propeller.
The engine must have been running "borderline lean" since the introduction
of ethanol in auto fuel and these factors may have tipped the balance in
favor of engine stoppage.
My experience reminded me that the three most useless things in aviation
are:
1. The runway behind you. (Luckily, I started the takeoff with all of the
runway ahead of me.)
2. The altitude above you.
3. The fuel you didn't put in the tanks.
In nearly 61 years of flying, this is the first time an engine has quit on
me at takeoff, and I'm glad things worked out the way they did. Back in the
1920's, Hereward DeHavilland (Geoffrey's brother) said in essence:
"In order to survive, the aviator must be continually apprehensive."
He was so right!
Automotive gasoline has contained ethyl alcohol (5 to 6%) for several months
in Canada, and this probably applies to the USA as well. This summer I
encountered a service station that sold fuel containing 10% ethanol! (It was
consumed by my automobile, though.) The above experience has caused me to
wonder how ethanol might affect the flexible fuel lines in aircraft and my
chemist/aviator friend and I are currently conducting tests on samples of
aviation fuel hose and automotive fuel hose by immersing same in fresh auto
fuel. We will keep you posted.
Cheers,
Graham Hansen (Pietenpol CF-AUN)

Fellow Piet builders and flyers,
Several weeks back, I posted a notice here about having a "regional" Piet
fly in along with Corvair College #21 that will be held on November 11,
12 & 13 at Barnwell airport [ KBNL ]
So far, no flying Piets have indicated they would attend. Some who
normally would come have scheduling conflicts. There are about 8-10 builders to
date who have indicated they will be here and want information on how to
build their Piets.
We will have my flying Piet, a static display of Don Harpers Piet on the
gear with corvair engine, maybe a second static Piet fuselage with tail
feathers, and we will hold a Brodhead forum type question/answer session in
my hangar to discuss building tips, do's and don'ts. I'll have a rib jig and
materials avaliable for those who want to learn how to build a rib.
any questions/comments, let me know

Don,
I love the matching paint. A Chief and a Piet, what a great combo to tag team
boring holes in the sky.
Thanks for sharing the picture.
Bryan
Jack,
What a great idea for the radio and transponder mount. With that set-up I could
probably source a used Narco transponder.
Brilliant idea, thanks,
Bryan

HI Gardiner,
I have actually been thinking about remaking my center section to make it b
igger for the fuel tank. I was making=C2- mockups today and calculating h
ow much fuel I could get in either the nose or center section. I can get ab
out 12 in my current center section and about 11 in the nose as I have all
the coils, switch, etc. all mounted behind the firewall.
I don;t like=C2- having to climb on a=C2- ladder to=C2- fuel the wing
=C2- but don't like having fuel in the nose right near the coils and coil
switch either. so making a new center section=C2- may be the easy choice
; i.e. fast than making two fuel tanks.
Thanks for the information on your center section. It sounds=C2- like you
are making really good progress though on getting her flying again. I like
the name Repiet; it fits.
cheers,
Jim B.

Folks
Well I=92m done working on my 3D Pietenpol airplane computer model. I cou
ld
add more detail, but its time to start building the real deal! Fall brings
an end to the flying season and the beginning of the building season! The
goal last winter was to learn how to build a Pietenpol by first building a
3D model of it on my computer. My thoughts where to make the mistakes
building in the virtual world before destroying the valuable wood downstair
s
in my shop. I=92ve found I am not very good at visualizing how all the piec
es
of the plane would fit together. So this little exercise worked out great
for me. I downloaded Google Sketchup 8 to draw the model. I probably have
over 500 hours in the drawing (yea I know, I could have used those hours to
build the plane). I used to have to look through dozens of pictures to see
how a part was used, now I just pull the drawing up, zoom, pan and rotate t
o
see how something fits on the plane. While not the original intent, some
folks have asked me offline if I could make the model available to them for
their build. So after discussing it with some senior members and friends in
this group. I=92ve going to try and make it available to the group. But fir
st
I would like one or two people to review the computer model and honestly
tell everyone (including me) what they think. I=92m looking for people that
have a good knowledge of the Pietenpol, preferably someone who has built th
e
real deal. The second thing is they have to know computers well enough to
help with any problems that might come up. If your interested, please email
me offline. I=92ll pick the 2 most qualified people and send them the drawi
ng
to review.......

PS: You can=92t build a Pietenpol from this drawing. It was intended only t
o
show how all the pieces fit together. You still need to buy the plans from
the Pietenpol family to build the plane!

Yes=2C they're 3/4 unrouted on the CC. I live in Brooklyn Park and would l
ove to have you stop in and take a look - as long as I could do the same so
me time. Feel free to give me a call sometime. 612-210-4103. Aircraft Spr
uce just emailed me today to let me know I'm on the 'first come=2C first se

y give me a clue on when it would ship either.. I so love good customer se

your center section=2C you went with the 3/4" unrouted spars? That's what
I ultimately decided to do after much consideration. If I remember correct
