I received my set today. Absolutely beautiful. The finish is far better than I
thought they would be and the dimensions match the plans nicely. I like that they
are flat and I can bend to the size of my wood parts. I know a lot of folk
have condemed the bulk manufacturing of metal parts as each plane is different.
Im sure there will be parts that will apply to. Im very happy with them and
recommend Georges parts to anyone. Its going to save me a lot of time and hassle.
Thank you George, your payments on its way!

I am collecting pieces a little bit at a time, so No, I have not gotten the hinge

Are you going to make multiples of the pulley brackets as well? Let me know if

I guess I don't get the rush to "get done". If I rushed anything during the
10 years it took me to build the Piet, it was the yard or house repair wok
I had to do before I was finally able to go out into the hangar and thorou
ghly enjoy making each and every part (that I was capable of making) of my
beloved Pietenpol. The whole project is "tedious" I suppose, but that was j
ust part of the whole experience. If one really wants to "get done" fast, j
ust go out and buy someone's finished project.......
I'll probably get flamed for this.....

I agree with you, Dan. It took eight years for me to build mine, but I made
nearly every single part of it and enjoyed it thoroughly. Once it was done
and flying, I felt sort of lost - not knowing what to do with my time in the
evenings. After a year I bought an RV-10 kit and have enjoyed building it,
but not nearly as much as I enjoyed the Pietenpol. There's just something
cool about finishing an assembly where you made all the parts. With a kit,
you're just assembling parts some factory made and it's just not the same.
Still, it's nice to have an airplane project in the basement.

With you, Dan! Funny what you said about the house work. I even abandoned a
kitchen remodel! All that's left is replacing the linoleum with tile, but
the raw edges of the old linoleum keep curling up.so I keep cutting it back,
so we don't trip over it! My wife has had saintly patience.

Hi Dan....why do you think what you said was going to "get you flamed"? Your reading
more in to it than what was intended. Our situation here in Australia is
a little different to the USA. Materials are not as easily obtained and are considerably
more expensive than you guys can obtain them there. I dont have the
tools to make the metal parts in an efficient way and being very time poor due
to young kids and running my own business, buying these parts ready made will
make my build experience more manageable than cutting parts out with a hacksaw.
Im in no great rush to get this built but I know my current limitations.
I love building with wood and have the tools to do this. I guess since im a trade
certified Watchmaker I could build all my own instruments and am curious as
to why you guys didnt make yours if its so important to make every single part?
George has gone to a lot of effort to produce CAD files for these metal parts
and I for one appreciate his time and highly recommend his product. Lets all
build with respect for each others personal situation.
Sunny side up!

I agree Dan. The only time something got tedious was when I had to redo a part
that I screwed up. For me the journey has been a lifelong dream and now that I
am in the final stages of completion, I almost dont want it to end. I guess I'll
have to build another.

No- there is no extra weight behind the CG. Everything is to plans with the trim
system (aluminum) installed due to my weight 280lbs. Holding stick pressure
it fine but I prefer trim to assist with that. Also, the weight of my trim system
is 1.45 lbs. acceptable to me, not excessive by any means!
The outside bell crank arms are for two reasons: First - I like the look and nostalgia
of it and two-it keeps the control cables off the stabilizer. Same outcome
different design, that's all.
No stops on my control stick and the throw is acceptable with others who responded.
Frankly, I see no reason to change anything at this point.
As for aft CG, my weight is a big factor as well as keeping everything light. I
have only necessary gauges with no compartments or accessories. Taking bets I
come well within overall plane weight!

Hey Guys..
on the straight axle, i was wondering what size bungees you used..??
i remember the last plane i built i tried to use something like 1/2 inch and discovered
that it was almost impossible to wrap...preload... and adjust.. so i
ended up with about half hat size... like 1/4 inch stuff.
it was a lighter plane..
i'm thinking longer lengths of 5/16 or two lengths on each side.
BTW ratings i found were
5/16......... 350 lbs
3/8............400 lbs
1/2............ 450 lbs
these are on a single strand of cord..... so more wraps of smaller cord could be
as strong as fewer wraps of large cord with more control of tightness right
??

| Subject: | Kennedy Space Center Flyovers |
One positive for the end of the Space Shuttle program is they have
reopened the space center for flyovers. Took the opportunity to fly the
length of the shuttle landing facility this morning. The runway is 3
miles long, and it took 3 minutes to fly the length. The only rule is
you have to stay above 500 ft. It was taking so long I called the tower
when I got that far and said "When I finally get to the end of the
runway I'll make a right turn and depart to the west" Quite a thrill
after watching the cockpit views of the shuttle landing on this same strip.

Ben Hi from England.
What a positive that is to fly over Kennedy SC. Almost seems like an
enlightened decision by someone.
I only hope our fashion here to copy the US extends to this liberal
approach to aviation. I'm sure it wont based on present conditions.
The Airspace being grabbed for the 2012 Olympics in London is crazy.
Enough or I'll be ranting.

I just had to jump on GoogleEarth and go check out what a place named

Mead, Peasedown St John, Bath, BA2,UK. More words in the name than there
were buildings . I can just imagine what it must be like flying over that
countryside in a Piet. GORGEOUS! Compare that countryside to what you

Tom Hi!
Quite a difference! Most of our fields don't get any bigger than 20 acres, 10 is
normal. WOM is 1700' X 100' of well drained grass.
It is great flying here but crowded getting around airspace restrictions sometimes.
I'm lucky as my Strip is under the Bristol CTA and the Radar service given
is second to none. A few nights ago with 6 'Heavies' coming into Bristol International,
all sorts of speed control to get them on the ILS they still had time
to ask me whether I was having a good flight and where I had been.
The video is great and all proof that a Corvair flies! Sounded good. Hope that
doesn't start any contention!
I'm flying an old Corben with a A75. Great Airplane and good fun. I've finished
with the 'plastic' speed machines. My brain cant cope!
Old and slow...got to be the way.
Regards
Gerry

We know Mr. Purtee is very generous in giving rides in his Piet, but if you keep
referring to him as Ken Perkins, he might not offer you another ride. Then again,
maybe Kevin will take it as a compliment.

it was a lighter plane..
i'm thinking longer lengths of 5/16 or two lengths on each side.
BTW ratings i found were
5/16......... 350 lbs
3/8............400 lbs
1/2............ 450 lbs
these are on a single strand of cord..... so more wraps of smaller cord
could be as strong as fewer wraps of large cord with more control of
tightness right ??

Hi Jeff,
Like Jack, I also used 1/2". I concur that it is a real bear to stretch, bu
t necessary. Douwe Blumberg told me about these mega-jumbo plastic "wire ti
es" that are sold at Home Depot in the heating and air conditioning departm
ent (by the duct work). There is a special tool that they also sell to tigh
ten them. I used that tool to cinch the bungees together.
Ideally, one would need three men and a boy to help with this bungee-stretc
hing operation. I have done it alone, by first looping and attaching one en
d to the axle by itself, then stretching and lacing, then finishing by usin
g that aforementioned tool to fasten the tail end. Very difficult without t
he extra help to be sure.

Dan,
I also used scatter graph with smoothing. Adjusted the scale in page setup prior
to printing. It was trial and error. Adjust, print, measure, adjust, print,
measure, etc...
This may depend on the printer you have.
Hope this helps.

>>OK ! I used the scattered graph to plot the Clark Y airfoil for my propeller.
How do I scale the graph so that when I print it is in the correct scale ?
In this example " Inches " PDF attached.

Ben,
Very cool picture. Made me think the Piet and Space Shuttle have something
in common, they both glide like a brick.

Fantastic ! Thank You. Those are the airfoils located at specific stations on
my prop profile. Did you accomplish that with excel or a CAD program? If Excel,
how did you do it ? Much appreciated.

I used Pages, which is part of iWork (Mac). I just took each jpg of the airfoil
and made them the width you specified while retaining the original proportion.
We don't need no stink in' Excel!
Actually, I am sure that one of the computer gurus on the Forum could have found
a better way to do it, but I thought that doing it this way might work. Glad
I could help.

Hi I agree with Jack completely. Stretching the bungees is a 2 person job.
Practice stretching and leave the beer for after you are done.

Didn't realize that the "tail strength" was something that needed to be addressed.
So, with your built to the plans (apart from larger external bell crank, trim
system, and fully sheeted plywood fuselage that only adds 1.45 lbs aft of
the pilot) Pietenpol, it will be interesting to see how far back you have to move
the wing..at 280, I guarantee it will have to come back, just curious to see
how much.
