Thanks so much for facilitating (I DO hate this verb) the effort.
JM wanted to visit me and my project last summer; alas, I was to be at
OSH so could not accommodate him. I see my small contribution to Mania
as an act of penance and, hopefully, goodwill.
In an age of Feds throwing Billions to Bailouts, I'm warmly reminded of

Good evening everyone,
We are emailing this evening to distribute the final update regarding
Markle Mania 2010, the effort to help Jim Markle keep his Pietenpol
project. We have received 73 generous donations out of 78 that were
pledged, for a grand total of $6490.50. No further donations have
arrived in the past few weeks, so I think it is safe to say that we can
draw this to a close.

This was primarily for thermal expansion and secondarily for stiffness.
It had nothing to do with the transition to turbulent flow, as the SR-71
operated at a very high Reynolds Number, even at "low" speeds.

Subject: | Re: Riblett 612 and angle of incidence |
This is how I'm doing my ribs: Spars are perpendicular to the chord line.
The lower surface of the Riblett 612 at the front spar location is quite a
bit below the read spar location, so I've built a spacer into the truss.
The standard 4 3/4" high spar will sit on top of the spacer and just fit to
the top capstrip. If I remember correctly (don't have my notes here at
work) the front spar still sits slightly lower than the rear with
respective to their positions in the FC10 section. When it comes time to
mount the wing I'll do the math to put the wing at the right angle so that
when the wing is at cruise AOA the fuselage will be level. That's the great
thing about building a Pietenpol, you can leave those decisions until you
have to make them.

Tim, It is just a med-heavy paper adheasive tape, with 1/8 inch holes in it. They
carry it at your local Home Depot, or Lowes. It is not actually dimpled,
it has holes, but it would probably have the same effect. I might try a sign
shop for some vinal tape as Jeff suggested. I'm not expecting a drastic increase
in performance, or economy, just a little. It also just gives us something
to experiment with for some thing to do. The perferated drywall tape, by the
way, is an easy way to get acceptable results on your drywall projects, I can
frame, but I hate drywall, and the sticky back tape makes it a little eaiser.

Dan.
I tried to build the 612 the same as the FC 10 per the drawings. 90 deg. with a
spacer T88ed to the top of the spar to rib. Harold R. suggested I use a 1 deg
angle of incidence for best performance. I would just make the change in the
cabane height. to achieve the 1 Deg. Keep in mind that my wings are clipped 2
Ft, much like a clipped wing 4412 on an earlier Piet that performed great but
much faster on landing speed. I am sure you will be satisfied with the glide using
the 612, approaches the J3.
Pieti Lowell
I watched the videos Jeff B. put on Youtube of your talk at Brodhead
last year. You mentioned that you kept your AoI of 2 degrees from the
FC-10 and that you'd probably like to see it at 1 degree or less because
at flat out cruise you've got to apply a significant (30-40lbs) amount
of forward pressure on the stick.
The question I have is this: did you build the angle of incidence into
the spar orientation in the ribs or did you keep the spars at a 90
degree angle to the wing chord?
Also, looking at the Riblett 612, I see that if you keep the front spar
the same distance from the leading edge as the FC1-1, 6 inches, that
dictates that the front spar and the rear spar will not be aligned,
vertically - the front spar must be shifted down an inch or so to fit in
the rib with respect to the aft spar. How did you address this? Did
you even worry about it?
Thanks,
Dan

The 1 inch is correct but if you go 612 use 1/2 inch to get 1 Deg.

Hey Don,
Great minds think alike eh?
I talked to my friend at Old Rhinebeck (owns the beautiful "626" that used
to fly there) since they are really good at the period look. He directed me
to Universal Overall company as the only place he could find old cotton
coveralls. Ck out their site, they have cotton coveralls with hidden
buttons. I'd have somebody put buttons down the front. They come in many
colors, but White or unbleached probably would look great.
I just got a pretty good old Mobilgas image that would certainly have that
thirties look, and the kind folks from this site have been sending me stuff
too, so we'll see. Let's talk and see what we come up with. Being an
artist, I can always clean on of these up or make our own. The important
thing to me is to get something that really looks old.
Sounds like we have an offer from a silkscreener to make screens (thanks
Jake!) which is the best printing way to go as it'll outlast and stay
fresher than a heat transfer. The ultimate would be to have it embroidered,
but I'll have to ck out the price on that, and it probably is way overkill.
Don, let me know if you want to order a few coveralls with me, and anybody
else and let's put our heads together about a logo so we can get something
done before flying season.

Subject: | Re: Riblett 612 and angle of incidence |
Thank you, sir.
I'm just trying to think ahead a bit. If I can keep a true
parallelogram between the front and rear cabanes, rib and top longeron,
then there shouldn't be too much trouble shifting the wing back and
forth to adjust for proper CG location.
Well, I'll be a son-of-a-gun! If you placed the spar at the bottom of
the ribs, and built your cabanes exactly the same height, that would
build in a 1"3/32 difference between the front and rear cabanes, which,
of course, makes an AoI of 2.16 degrees. Furthermore, and this is the
beautiful part, shifting the wing back and forth wouldn't change the
angle of incidence.
Lowell, if you didn't re-adjust your cabane lengths and kept a shorter
one in the back, you might actually have a 4 degree angle of incidence.
Maybe I'm doing my geometry wrong... it's been known to happen.
Ok, enough dithering, hypothesizing, and pontificating. Time to get to
work.
Thanks again,
Dan

I have actually been in the "snotworks" working on my retractable gear
for the Cub. I am looking at hand crank version similar to what was used
in the F3F/F4F. Just 237 simple turns of the crank and I will never be
passed by a Pietenpol again! If I slant my N-numbers it should be faster
as well.
But seriously folks, I have used CafePress for about seven years with
pretty good results. The better your artwork in the input side, the
better the output. I find a png file renders the best results. Wayne is
right in that the colors are not always vibrant, but what I am doing
does not require it and they are very durable, so I have been happy.
That being said and always looking for improvement, I am experimenting
with another online vendor on my next project.

Subject: | A Piet is a Piet |
Saturday was a banner day for Pietenpoling in central AR. There was an EAA
lunch at a far distant (12 miles) airport that I had decided to attend. The
wx was a vicious gale (5-7 kts) but there were no clouds and the temp was
a balmy 49 deg so, with the promise of cheap eats of the high cholesterol v
ariety, off I went.
With the conditions as they were I expected some bumps due to gusts but not
much else as the terrain here is like unto a pancake. Boy, was I in for a
surprise!
About half way to my goal I started feeling little nibbles of lift. Then su
ddenly I noticed the tail rise and my loosely held altitude of 1000' starte
d going up at a rate that I had never before seen in my Piet. I put the nos
e down and brought the mighty Ford back to idle but the climb continued. Si
nce everything else was out of my ability to deal with, I decided to just r
elax and see what was in store for me. Now this was not a head-knocking, co
ntrol fighting struggle to stay upright, rather it was smooth and calm like
an elevator.
3K came and went then 5K. Now, 5K was my all-time highest flight ever and a
s discussed a few months ago, that's the altitude where things get kind of
weird in a Piet. All of a sudden there is a voice in your head that whisper

Wave lift in AR? Who knew! Sounds like a grand day.
Here it's sunny, 36 degrees, winds aren't too high at 9mph, and my
exhaust is off and sent out for replacement.... humph.

There are only 2 reasons I'm interested in the dimple tape - better
climb rate and lower fuel consumption. If I can clear the trees/corn
stalks by a bigger margin, that's a winner. If I can save 10% on gas,
well, that's a nice bonus, too.
All this talk about going 24mph faster in a Pietenpol... good grief,
people! What on earth for?!??

Hey Don,
Great minds think alike eh?
I talked to my friend at Old Rhinebeck (owns the beautiful "626" that
used
to fly there) since they are really good at the period look. He
directed me
to Universal Overall company as the only place he could find old
cotton
coveralls. Ck out their site, they have cotton coveralls with hidden
buttons. I'd have somebody put buttons down the front. They come in
many
colors, but White or unbleached probably would look great.
I just got a pretty good old Mobilgas image that would certainly have
that
thirties look, and the kind folks from this site have been sending me
stuff
too, so we'll see. Let's talk and see what we come up with. Being an
artist, I can always clean on of these up or make our own. The
important
thing to me is to get something that really looks old.
Sounds like we have an offer from a silkscreener to make screens
(thanks
Jake!) which is the best printing way to go as it'll outlast and stay
fresher than a heat transfer. The ultimate would be to have it
embroidered,
but I'll have to ck out the price on that, and it probably is way
overkill.
Don, let me know if you want to order a few coveralls with me, and
anybody
else and let's put our heads together about a logo so we can get
something
done before flying season.

Subject: | the vintage coverall project |
Hey guys (...and gals??)
Some people are interested in getting some vintage coveralls with some kind
of cool old logo silkscreened on the back.
Anybody who is interested contact me offlist at douweblumberg@earthlink.net
Right now I'm thinking that everybody can order their size and color and
have them shipped to me. Then those who want vintage buttons added can have
that done with mine.
My friend will do the silkscreening. The old mobilgas logo I like is only
two colors so that'll only cost $20 each and some more if you want your name
on the front. If you want a different logo than what we all come up with
it'll be more, especially if it's full color and you have to pay for the
screen charge yourself.
I think the coveralls are around $36
Let me know who is interested and I'll get you the details and we'll all
figure out what logo suits us, or if we want to do more than one.

Subject: | Re: Riblett 612 and angle of incidence--No, no, TWO |
DEGREES!!!
Thanks, Lowell and Dan. This has uncovered something in my own peculiar case.
I have the BP FC10 airfoil with an added nose, but am still using the original
2 degree (1") difference. Thus with a different airfoil nose, I have a larger
radius at the nose, resulting in a slightly different (higher) chord line,
and will have more AoI than I thought with my application. I'll take a look.
I can still change it if I need to.
However, with an A65, lift and climb are more important to me than speed, so I
am erring on the right side in my mind with more AoI, but I don't need more pitching
moment, etc.

Shad,
I was just pulling your leg on the drywall mud bit. I think your idea might work
very well, and admire your ability to visualize that connection. For the natural
permanence of the vinyl sign material, that might work better. I have
never seen it, though. In fact, I have never used that particular adhesive dimpled
paper tape with drywall, but have used the plain paper and the adhesive
nylon tape. I love carpentry, but also hate doing drywall.
If the adhesive perforated paper drywall tape works for this, we will have to rename
it "plane paper."

They carry it at your local Home Depot, or Lowes. It is not actually dimpled,
it has holes, but it would probably have the same effect. I might try a sign
shop for some vinal tape as Jeff suggested. I'm not expecting a drastic increase
in performance, or economy, just a little. It also just gives us something
to experiment with for some thing to do. The perferated drywall tape, by the
way, is an easy way to get acceptable results on your drywall projects, I can
frame, but I hate drywall, and the sticky back tape makes it a little eaiser.

Subject: Pietenpol-List: A Piet is a Piet
Saturday was a banner day for Pietenpoling in central AR. There
was an EAA lunch at a far distant (12 miles) airport that I had decided
to attend. The wx was a vicious gale (5-7 kts) but there were no clouds
and the temp was a balmy 49 deg so, with the promise of cheap eats of
the high cholesterol variety, off I went.
With the conditions as they were I expected some bumps due to
gusts but not much else as the terrain here is like unto a pancake. Boy,
was I in for a surprise!
About half way to my goal I started feeling little nibbles of
lift. Then suddenly I noticed the tail rise and my loosely held altitude
of 1000' started going up at a rate that I had never before seen in my
Piet. I put the nose down and brought the mighty Ford back to idle but
the climb continued. Since everything else was out of my ability to deal
with, I decided to just relax and see what was in store for me. Now this
was not a head-knocking, control fighting struggle to stay upright,
rather it was smooth and calm like an elevator.
3K came and went then 5K. Now, 5K was my all-time highest flight
ever and as discussed a few months ago, that's the altitude where things
get kind of weird in a Piet. All of a sudden there is a voice in your
head that whispers, "You don't belong here", and the Piet seems to be
too small and too delicate to be that high. As all that was bouncing
around in my brain I passed 6K then 7. Going through 8 thousand feet
things got eerily quiet and I could see the curvature of the earth and
stars were appearing in the blackness that was gathering around me. I
think it was real but it could have been because I had my eyes closed
for a while. Prayer Donica know.
Well the lift subsided just as gently as it had come and I had a
long,long,long glide to the luncheon airport but it was a crosswind to a
paved runway and I just don't do that so I did a 180 and headed back
home. Of course I took the great circle route around my earlier
adventure.
Now my Air Camper is about as stock as any one out there and it
has served me well, even setting the absolute altitude record for
Pietenpol aircraft in Lonoke County. I've flown it to OSH twice, C37
often, flown with geese and egrets and herons, had an unscheduled
landing in a bean field, done touch-and-go's in farm fields all over the
fruited plain and never ever felt like I wanted or needed a more
powerful engine, different airfoil, pushrods, radio, lights or any other
thing more or less than what Mr. Pietenpol suggested.
I do have a high performance (read high dollar) head that
promised better fuel economy while delivering higher RPM, power,
acceleration, smoother idle, etc. I don't think the engine or the
airframe can tell any difference.
As for adding dimple tape and VG's and other innovations for no
apparent purpose, I'll take a pass. My simple, cheap, honest,
easy-to-maintain and joy-to-fly Pietenpol Air Camper fulfills it's role
perfectly.

Larry, I think you were in the Twilight Zone in your Piet at 8k ft. I lived
at 8k ft. in CO for 11 years and never saw stars during the daylight hours
(except for that big one at the center of the solar system).

One must breath the exhaust of a Ford to have such a flight, A cure would be, try
looking off to the right in place of the left for the first 20 minutes after
take off.

Many years ago I had a chance to read through the SR-71 pilot's manual.
The one thing that I remembered was that it got its best MPG at the
highest and fastest it could go. I think it was way above Mach 3, and it
was something like 80,000 feet. Just mind-boggling numbers.
