| Subject: | Speaking of Poplar |
Some years ago a fellow cut down a big poplar tree that he grew in his yard, had
it dried and milled and built his entire Pietenpol out of that tree. I forget
what happened
to the plane -- I think it was lost in a fire. There was an article about it in
one of
the old newsletters.
Poplar, Wis., is also home to Major Richard Bong, America's ace of aces. They have
a
great museum with a P-38 at nearby Superior and tells Dick Bong's story. So if
you're
ever in the Duluth-Superior area, stop in there.

Insects don't like poplar so it has a natural resistance to infestation. From what
I have read.
I like that part too. It keeps one from building an inferior model

Subject: Re: Pietenpol-List: Speaking of Wood Selection...
Yep: Kiln dried and stored in a warehouse. Sweet!
And, I went to a new computational websearch engine called
Wolframalpha.com to look up the weight difference in Poplar and Sitka
Spruce. It spits out the density of Sitka at .335g/cm3, and poplar at
.38g/cm3 ... And the strength properties listed are extremely close.
So I don't think I'll be adding a bunch of weight to the plane, and
keeping the dimensions the same on all wood parts would yield about as
much weight as if I was sloppy with glue or something. The difference
(if I am looking at this properly) is .38 minus .335 or a difference
of .045/cm3 or about 13 percent heavier...13 pounds per 100... for a
dollar savings of a lot!

I bought a wonderful 70% project which includes the original "Jenny"
type landing gear. Rather than rip out the work in place I'm going to go
ahead and stick with that gear. Question. The solid steel axel appears
to weigh about a ton and a half. My thought is to substitute a steel
tube or failing that, replace the center half of the solid steel axel
with an aluminum tube, sleeved over the axel end pieces. What say the
assembled, and far more experienced, masses?
Also, beyond asthetics, what are the considerations on windshield
design? I'm leaning towards the simpler single piece, bent plastice
motorcycle type althoough the classic framed type has more "Classic"
appeal. Is the simpler lighter? What say you?
Thanks in advance

| Subject: | Re: Poplar (Yellow) and a corvair engine |
Steve, there's a perspective I hadn't considered. We live in Central
California, and it's a dry (too dry) place. However, I also plan to hanger
it, and varnish all the parts first.
We grow approx. 25% of the nations food right here in Fresno county. Can
you believe that? One county, 25% of the food. I thought it was a joke or an
exaggeration, but it is true (unless the farm bureau is lying... It still
sounds high to me). It is possible because of the growing conditions, and
the fact that in the 50's/60's they built an aqua-canal system to send water
here, because we are an old dried up lake bed with no real water of our own.
Big news here is that the government has diverted the water this year (a
drought year for the 4th or 5th year in a row) due to an environmental law
protecting a bait fish that is common in many parts of the US, but would be
somehow endangered in the delta where it lives now. Now they are plowing
the crops under for lack of water, and food prices nation wide are about to
go up quite a bit as a result.
So, I am wishing we had some rain here to rot my wood :o)
All that because I saw your tag line "Steve in a very damp Maine."

Steve,
My axle is 1-1/2" diameter, .188" wall 4130, heat treated to 160,000 psi
tensile strength. The loading of the axle is a bit unusual - if you look at
a shear and moment diagram for such a structure, the axle is under a
constant bending moment from bungee to bungee, which means the stress is
constant all along the axle. Landing loads can put some pretty high
stresses on it (I broke my first axle during a forced landing, hence the
heat treating of the new axle).
As for windshield design, the curved design is considerably lighter and
infinitely easier to make than the framed type.
It all depends on what you want. If you want good performance, build a Piet
with standard "Cub-type" gear, curved windshields, etc. If you want the
"classic" look, go with the sraight axle, wire wheels (with or without
covers) and framed windshields, but understand that all those things add
weight and hamper performance, particularly on hot days.
Good luck!

I try to use light oil, but the truth of the matter is that enough
"stuff" flies, drools, and drips back from the engine that things
stay fairly well lubed regardless.

Pieters,
Looking for pics of a Piet with regular gear, coil spring shocks and
motorcycle wheels. Any info on such an animal will sure be appreciated. don't
remember any but it's been a long time since I Pietered.
Using 1/2 gallon milk jugs is THE answer for wing flotation. You can fill
those spaces entirely. That thing would float forever

Hi Corky
Several of the Pietenpols built in the UK have the coil spring and
motorcycle wheels.

Pieters,
Looking for pics of a Piet with regular gear, coil spring shocks and
motorcycle wheels. Any info on such an animal will sure be appreciated.
don't remember any but it's been a long time since I Pietered.
Using 1/2 gallon milk jugs is THE answer for wing flotation. You can
fill those spaces entirely. That thing would float forever

I hadn't really thought of engine drips, etc. from oil changes and all lubing
the sliders. Probably only need to lube them for the initial setup and check after.

This is not directly Piet related other than it has to do with a

and he's had a ride in my Piet. Anyway, today his V-tail Bonanza
took to the air after what seems like years of he and his kids and
dog laboring over getting it airworthy again. When I got to the
hangar about 1 PM to continue working on my A75, there were guys with
pencils and checklists crawling all over Steve's airplane and a while
later, it took off. Engine didn't miss a beat, the airplane must
have been over the airport for a half hour, and I guess that means
everything stayed in the green and he's back in the air again.
Having the Bo back will probably break Steve of his need for slow
flight so he'll probably drop off the list now ;o)

Corky-- if you can, ask for ANYTHING that rides on aluminum alloy rims---they'll
be lighter and they can be polished to appear like they
are chromed. I have 19" aluminum alloy rims on mine.
40 spokes per wheel are BEST but most bikes don't come in those anymore....32 is
the standard I believe anymore. I happened upon a set
of 40 spoke aluminum alloy rims after searching 3 motorcycle boneyards and many
stores.
Sun (you'd have to Google them) sells alum. rims off the shelf--any size---perfect
if you're willing to spend the money.
You can always just go to the guy who made the wheels (and airplanes) for the movie
Flyboys....he sells wire wheel kits with all you need
including a video on how to lace and true them.
http://www.airdromeairplanes.com/HeavyDutyWheels.html
Wheel kits ready to be laced with 2 tires, 2 tubes and 2 bearing sets
sell for $495. This also includes a step-by-step detailed video.
The weight of 2 hubs is "about" 2 lbs.
(We couldn't get them to register on a digital scale.)
The weight of ONE wheel complete with tire and tube is 18 lbs.
So, two COMPLETE wheels will weigh 36 lbs.

| Subject: | Re: Axels, ahem, axles!! |
The axle on NX18235 is 1 1/2" X .120 wall thickness and is not heat
treated. No brakes are installed so the length of axle extending beyond
the bungee's is shorter than a brake equipped Pietenpol. This helps to
limit the bending stress on the axle.
The axle has withstood some teeth jarring landings just fine.

hmmmm, .188 wall thickness? I'm not looking at them right now, but
what do the plans call for?? I don't know, but I think I screwed up and
used thinner wall tubing. Already painted and installed, but if I need
to replace or put a doubler tube inside at least past the bungees . . .

Steve,
My axle is 1-1/2" diameter, .188" wall 4130, heat treated to 160,000
psi tensile strength. The loading of the axle is a bit unusual - if you
look at a shear and moment diagram for such a structure, the axle is
under a constant bending moment from bungee to bungee, which means the
stress is constant all along the axle. Landing loads can put some
pretty high stresses on it (I broke my first axle during a forced
landing, hence the heat treating of the new axle).
As for windshield design, the curved design is considerably lighter
and infinitely easier to make than the framed type.
It all depends on what you want. If you want good performance,
build a Piet with standard "Cub-type" gear, curved windshields, etc. If
you want the "classic" look, go with the sraight axle, wire wheels (with
or without covers) and framed windshields, but understand that all those
things add weight and hamper performance, particularly on hot days.
Good luck!

Guys, The WACO fly-in was FUUUUUNNN today.- Dad drove the 1932 model A 1
1/2 ton truck up today, and parked inside the- aircraft parking.- A fel
low walked up after a while and asked Dad if he could pull up tight to a mi
nt looking Waco (UPF-7 i believe) so they could take some time period photo
s of the 2 togeather.- Well it turns out that it was Bill Knight's WACO,
who also owns the "Last Original" Pietenpol up at Brodhead.- After talkin
g about Piets, airplanes etc, he made the comment "What a nice day, wish I
could find someone who wants to go flying" (wink wink), he offered me, Dad,
and my wife a ride in his WACO.- It was a blast!- And how in the heck
someone ever flew, (landed rather-)one of those from the front cockpit is
amazing, the top of the pannel is about the top of my forehead, and the fr
ont pit is about 3 feet wide.- He let me fly a little after we got to alt
, and it flys nice, light ailerons, and heavy rudder.- It is nice to see
the
commrodery (sp?) of the airplane brotherhood, especcialy Pietenpol guys.
- I can't think of a nicer group of folks anywhere.- It goes to show, n
ot all those with money are buttheads, some don't forget where they came fr
om, and where we are all headed.- I will gladdly develop the black and wh
ite digital photos I took of dad's model A with Bill's Waco and give them t
o him at brodhead next month.- And I don't want to forget to mention, it
was great to see Tom Brown of Colby Wisconsin (Corvair Piet "Brown Aero"),
and Skipp Gadd (GN1) from Hales Landing WV.-

Looking forward to seeing Y'all next month for the 80th

If "ramp appeal" is important to you then the Jenny style landing gear
and 3-piece framed windscreen are good choices.
At the Father's Day fly-in at our home field of Stanton (SYN) the
Pietenpol was parked with a bunch of shiny fiberglass light-sport
aircraft and a bunch of Cubs. Which airplane do you think had the crowd
around it? The Pietenpol.......
Replace the solid axle with tubing. It is still heavy but better than a
solid axle.

| Subject: | Re: Continental Motor mount plans-- downthrust specifically |
The downthrust on NX18235 is per the plans. It displays a slight
tendency to go "nose down" when I let go of the stick. It is the same at
all throttle settings so that indicates it is an aerodynamic issue and
not related to motor mount downthrust.
Any builder weighing more than 180# might want to consider extending the
motor mount 1 or 2 inches.
