Wasn't always so pleasant. Our first few trips to Brodhead in the late
80's early 90's made us not ever want to go back. For new guys on the
block, my wife and I were treated pretty nice by most but pretty lousy by
the rest. They were a pretty snobby group and you'd think they had just
got off of a Lear jet from the left seat instead of a Pietenpol. We were
really turned off by that I didn't care to go back for quite a few
years. Since Steve Eldredge started this e-mail list in Utah (and Grant
MacLaren poured his volunteer time into putting together a great
newsletter---which some still bad mouth because they lost a measly $10 or
$15 bucks over !!!!) the group has really come together. There might
have been the good old boy click thing going when we first got there, I
dunno. Anyway, what was super about the last meeting is that I got to
meet people from the list in person. Really neat and you feel like you
know them already. The new blood in the group over the past 10 years has
really improved the quality of the planes we are producing and the
willingness to share as much info as possible to get more of these in the
air as time goes on.

Chuck:
I was wondering how long it would be before the Hiebie Jiebie Emails would
start rolling in. I'm also very concerned about safety. These bolts are what
holds the control sticks to the torque tube. Dad used the wrong size ID tubing
(to build the bushing/tube inside the torque tube at the stick pivot point)
for a bolt to fit in and it rattles a little. A 1/4" bolt is too small and if
he bores it out, to a 5/16"? The bushing that's welded inside the torque tube
will be paper thin. I don't think the treads in this application are going to
be an issue. I will use aircraft bolts, even here, if I can find a 7mm with
a shank instead of threaded all the way up.
The alternative, according to my builder (Dad), is to rebuild the entire
control system. I can't see it, so I kinda have to take his word on it for now.
We have several week to address the problem, I just like to resolve things
ASAP.
I appreciate your concerns and constructive criticisms, please let me know if
you think this is still a safety issue.
Thanks in advance,

Max,
Patience is the word. One thing worse than " 90%" completed is 100%
completed, hangared, insured and full tank while watching Mr Johnson and Nathan
Moss
fly and have fun in your our creation. Let's imagine a little scenario," suppose
Teddy Kennedy had flown several hours in his youth and a little along the way
then he decides to get his physical renewed so he can fly Bobbie III's 150
some weekend in Palm Beach. The Fed Drs say you will have to have the
cardiologist perform all those tests plus a max stress test, the neuro Dr perform
all
those MRara Is etc. Cost in excess of 13K. Teddy pleads that all he wants to fly
is Ted Brousseau's Piet. No way says Mr Fed Dr. Question: How long after the
final No from the Feds would it be before some action MIGHT develop on the
Sport Pilot issue. Not that ole Corky is implying that politics COULD play a part
in the passing of this loooooooong awaited priveledge.
Sorry I got off the subject Max, what I really meant to say in this little
note that you are mighty welcome to choggie east on I-20 and visit us anytime.
You might check with Mr. Edwin Johnson, who likes fine Scotch, and try to
arrange a little hop with him. He and Nathan Moss keep the keys. That's personal
so
I can't speak for him but he is a great guy.
Corky in La waiting for those idiots in Washington to get off of it and pass
the Sport Pilot issue while I can still walk to my plane even though it's now
with a cane.

Dave-- I'd go with aluminum alloy rims vs. steel for weight savings and 40
spoke if they have them over the much more common 32 spokes per wheel. 18
thru 21" diameters would work fine.

you'll want something like an 18-20" wheel. try to get one with the widest hub
you can.... if you can't find one with at least a 6" hub (and I doubt you will)
then you'll have to have some of your own hubs turned. Essentially your
just buying the rim ring.

Dave,
Aluminum, 21" and 36 spokes(72 spokes are lighter than 80), also get the
widest hubs you can as the angle of the holes will line up better if you
build 5 1/2 or 6" hubs.
Be sure you check the weld real close, I got 3 rims and 2 of them cracked at
the weld when I took the spokes out.
Another thing, when you get the tires, make sure they go with the rims, the
tires I got have real fat or wide beads and are a REAL pain to seat on the
narrow rims.

Chris,
I asked this question several months ago on this list and didn't get any
response. Asked around locally and decided it would be ok. The guy who did
my welding said I should not put any stress on the rim for 6 months, no
problem for me, to give the weld time to harden.
Also I think that once the wheel is re-laced, there will be a lot less
pressure on the weld.
Anyway I have one on my Piet project.

Subject: | Re: corvair conversion cost |
that's too large for a Corvair if you want to take advantage of the full horsepower.
at 2,000 rpm you're getting maybe 55hp at most. You need to spin it up
to at least 2600 static. It will unload to about 2800 or so on the rollout
giving you almost the full 100hp.
You'll need something like a 62x34 through a 66x29. I have a 66x29 on mine and
it gets 2700 static.

Subject: | "Hearty individuals" and cold weather open cockpit flying. |
--> Pietenpol-List message posted by: "Graham Hansen" <grhans@cable-lynx.net>
To Chuck G., who said it was 4 degrees F outside, and:
"Hearty individuals like Shawn Wolk and Graham Hansen, call this
'Pietenpol weather"!!!"
Well, I can't speak for Shawn, but this old geezer never flew his Pietenpol
when it was THAT cold! I guess the coldest was around 18 degrees F.,
but that was when I was young and stupid. Now I am old and stupid, but
not nearly so tough as I used to be.
On November 15, 2000 I flew my Pietenpol to commemorate the thirtieth
anniversary of its first flight. The temperature was -6 degrees C (or about
22 degrees F). The flight is well-documented by photographs and, if I get
a scanner, I'll post a couple. This anniversary flight was made on wheels;
there wasn't much snow. The very first flight was made using Federal
A1500A aluminum skis similar to the ones in Shawn's photos. Since then
I have used home-made skis made from ash and currently have a set of
old Federal SC-1 aluminum skis rigged for the Pietenpol. In recent years
snow conditions here have not been favorable for ski flying, but this winter
seems to be shaping up to be better. Usually February and March are best
because the days get longer, the temperatures moderate, and the chances
of getting a sunny day improve. My Pietenpol is an excellent skiplane. How-
ever the open cockpit is a serious limiting factor. A nice canopy for the
pilot
and a cover on the front pit would be great for solo ski flying. Installing
a
canopy in the front would be more difficult to accomplish.
A HISTORICAL NOTE:
75 years ago, in early January, two brave men took off from Edmonton,
Alberta in an Avro Avian two-seater biplane, on wheels, to deliver diph-
theria antitoxin to Fort Vermilion, about 500 miles to the north. The tem-
perature on the ground was -33 degrees F when they left. It was a night-
marish adventure and the round trip took several days. After landing at
various places along the way, they literally had to be lifted from the cock-
pits because they were practically "frozen stiff". This remains one of the
greatest feats in the history of bush flying. Their names: W.R."Wop" May
and Vic Horner.(The Avro Avian they flew was a wood-and-fabric open
cockpit biplane powered by an in-line 4 cylinder Cirrus engine. It was a
bit larger and heavier than a Pietenpol Air Camper, having a longer fuse-
lage and an extra wing.)
NOTE: Wop May was set up to be the 81st victim of Manfred Von
Richthofen on an April day in 1918, but the "Red Baron" was
shot down while chasing him at a very low altitude.Wop May
became a WW I "ace" with 7 victories.
Graham Hansen [Pietenpol CF-AUN is in the hangar at Camrose,
Alberta, where the current temperature is now
only -28 C (-21 F), and I think it will stay
there
for the time being!]

<< Would like to hear of your/our Post Brodhead tour and what plans you may

Corky,
It's good to hear you're back at it. Gonna have to make a bracket or
something in your front pit, to carry your cane. I put in a request for vacation
several months ago (7/16/04 to 8/16/04) but two weeks will be unpaid. They
have to get everyone's request in, before they hand out the OK...I'm still
waiting.
Assuming everything is GO, Fri./Sat 16/17th I'll be heading 180 to
check out some of our 'Texas' Pietenpols. Sun / Mon I'll head 090 to
Shreveport, La. I've got a sectional out here, and Shreveport has a double big
#8
shaped Class 3 Airspace. Those Magenta circles give me the Hiebie Jiebie's.
Where is your airport ?? The Sport Pilot will be passed by then, and from there,
We Will Fly 005 direct to Brodhead. Looks like about a 4 day trip. After
Oshkosh, I'd like to continue 360, up around Lake Michigan, and then 170 back
down thru the state of Michigan, to Columbus OH (big sister lives there),
then 090 to Wheeling W V (my hometown). From there, it will be 270 back to
Wichita KS. I'm sure there will be other 'Low & Slow' flyers that will join us
on some of the legs. Does it sound like a pretty good cross country trip ???

Max,
Doug Bryant did the same thing when he built the controls for my plane. Flew
it that way for about 15 or 20 hours, and couldn't feel the slack at all
during flight. About 80 hours ago, I used a piece of brass shim stock rolled in
a
tube shape, with the 1/4" bolt, to take up the slack. Grease both sides of
the shim. This application is in shear, so it's important to have the shank
all the way through the bushing, and use a caslte nut / cotter pin, because you
don't really tighten up the nut. I carefully check it on every pre-flight.

Most of the Continental A65's that I've seen, including mine, has a 72 X

Subject: | Re: (no subject) |
Best way to resolve the problem is buy a bolt that fits and run a static test on
it to prove it is stronger than needed by the standard safety margin for the
location. You will need to calculate the highest load the bolt will ever see
(pretty easy, just find the part that will break first in its load path) and
double it just to be safe. Test load the bolt to the double load and you know
the weak link will fail LONG before the bolt. I am a FIRM believer in using
aircraft grade hardware but it is just silly to rebuild the whole control system
when the load the bolt will see in the WORST case is probably 10% of its yield
strength. We don't use certified wood, engines, paint, fuel, props or even
the design. Safety can come from proper design and testing just as well as
from a "certified part" bin. If you show proper analysis of the load and a test
of the part to show it is up to the task the FAA won't give you a problem.
THIS DOES NOT MEAN YOU CAN GO AROUND PUTTING IN HARDWARE STORE BOLTS WHEREVER
YOU WANT!! (Yes I know I'm yelling) But in this case a little analysis and testing
would be a lot easier than rebuilding the whole control system.
Hank (Don't forget to corrosion treat the bolt) J

We made the mistake of building our hubs before locating rims. The hubs were built
to Howard Henderson's plans calling for 40 spokes.
We spent about three hours in a mosquito infested motorcycle boneyard looking for
a
matching set of 40 spoke, aluminum rims.
We found LOTS of 36 spoke rims. Many were new and still in the protective wrap.
We would occasionally find 40 spoke rims. Finally, we found a matching set in
usable condition. They were 19" rims from older Honda Goldwings.
Some of the bigger Kawasaki's also had 40 spoke rims.
The weight difference between aluminum rims and steel rims is minimal.
I would recommend that you find your rims BEFORE you build the hubs.
If I were to do another pair I wouldn't hesitate to use 36 spoke steel rims.
Greg Cardinal in Minneapolis
PS. As Dale and I were walking out of the boneyard with our hard fought prize
we noticed a pair of rims leaning against the building. The rims were, you guessed
it,
a matched set of 40 spoke, 19 inch, aluminum rims marked $20.00 ea. !!!!!

List,
I've found a motorcycle shop in Rosebud Missouri that has hundreds of used
motorcycle wheels sorted into bins. I'm going there Saturday to pick out my
Piet wheels. Any suggestions as to what to look for and what to avoid? Thanks.

Hank and Chuck:
I found a 7mm bolt with a 40mm shank at Metric and Multistandard in Irving
today. It is an 8.8 which is apparently equivalent to a grade 5 American bolt.
Your average hardware bolt is about a grade 2. I think this will be more
than adequate for this application. Hank, for curiosity more than anything else,
I will take your suggestion/advise and rig up a test. Chuck, a castle nut
would probably be a good idea. We were planning on using a lock nut, but a
cotter pin sounds good.
Mike and Chris
Thanks for the info on Aircraft Supply Co., I will make an effort to get by
there and visit with them sometime. They do not have everything; I called them
first thing this morning and was informed they don't have metric. I told him
Mike King said they had everything. I mean everything, haha. They are very
nice however and referred me to Metric & Multistandard.
I sincerely appreciate your help and concern for my safety.
Thanks again guys,
Max

That sounds even easier than the bolt test method. I would pull the bolt at
least every annual and re-lube and inspect.

Thanks to all who gave advise about the wheels. I've noticed from various
Piet photos that where the metal bracket (that attaches a wooden landing
gear to the fuse) - some have two bolts and some four bolts. The plans
(which are for a metal gear) show a bolt going through the bottom of one of
the struts, just above where it is glued to the bottom longeron. So....I'm
wondering if I should bolt through the struts, or through the wedges that
are in between the struts or both. Perhaps it doesn't make any difference
since the wood is just the stuff between two steel plates. I don't know.

If we don't have the Piet going by then, I'll at least escort for a leg or 2
in the Taylorcraft. Perhaps, I'll bring the digital camera.

Max,
A castle nun / cotter pin is standard practice in a rotational application.
Hank,
How could a homebuilder set up, and do a destructive test, and come up with
an accurate reading ? The ol' Sledge Hammer doesn't offer up any numbers !!
Everyone,
Keep in mind that these e-mails will go into archive, and for future
reference the 'Subject Line' should pertain to the text.
