Subject: | Need Help on Horizontal Stab. Diagonals... |
From: Stacy Clark
Subject: Re: Pietenpol-List: Need Help on Horizontal Stab. Diagonals...
Peter,
The problem I have is that the wood supplied by AS&S was too short for the swept
stab (two 1/2" x 3/4" x 48"). Anyway, this is the solution I came up with (attached
jpg's). Have no idea whether my "best guessing" is right, but it looks
like it disipates the energy. In the end I'll probably go back to "as plans"
as I discovered tonight that I'm missing 1" x 1" of suffcient lengths for the
elevators. Which means that as I "have to" order those I might as well order
the stuff for the diagonals as well. (The kit originally had two 1" by's of
sufficient length but they had to be sacrificed for the #6 side trusses as their
"supplied" trusses were all 36" long, i.e.: too short for #6. BTW, had to
rip all those down to 7/8" width [nos. 2 thru 6]).
Word of advise to all that are thinking of going through AS&S for their spruce
kit (3 pc. wing)...don't! If I had to do it over again I would have ordered the
standard Piet with one-piece and modified it to three piece. The way you must
buy it from AS&S with 3-pc wing is with their "Modernized Pietenpol" only.
They clipped me for about $300.00 extra bucks plus I had to eat the material
for the wing ribs which I already had pre-built (maybe I'll build some doll houses).
And of course the added bonus of having to ship it up here in the Alaskan
bush.
...Sorry to vent. (Sill working with, and achieving the impossible...) :-)

Stacy : I bought a set of atv tundra tires from a place called Flying K
Ent. Caldwell Id. They make (made ? ) a plane called Sky Raider. I wish
I had bought several pairs. The owner of Flying K was killed a couple of
years ago and I don't know if they are still in business. They were the
only source of these tires that I new of and I never tied to figure who
there vendor was. They should last a long time if you land on grass all
the time, but I think paved runways will ware them out in a hurry. They
sure look good in the Piet. Corky: The split gear is the only way to
go if you want to keep the weight down. Originally I was going to use
the Jenny gear, but after reading in the old news letters that the wire
wheels weigh up t 18 lbs each alone, then there is the massive axel to
go with them, I went the other way. I am bound and determined to stick
with the anemic Ford A, so weight savings was crucial. I also dumped the
brass-copper radiator ( 19 lbs ) for a VW Golf radiator at 4 lbs. I sure
hope it all pays dividends in the future. Leon S. in Ks. 6 years into a

For those of you actively flying, it might be a good idea to check to see
if President Bush is in your area. I found this
site on the FAA's web page that shows the active and upcoming TFR's coming
to a town by you. I was at an airshow in
Toledo this past weekend and after the Thunderbirds landed, Air Force One
landed about 45 minutes later. Luckily, I drove to
the show. http://tfr.faa.gov/tfr/jsp/list.jsp

Subject: | How many ounces does it take |
Group,
I would like some opinions from the "older wiser ones" (more experienced)
who have covered a Piet or two. My thinking ,right now, is to cover the wing
and tail with medium weight (2.8 oz.) and the fuselage with light weight (1.7
oz.). The wing does the work, so I thought it needed to be a heavier grade,
and then cover the body with something light, as it does not take the same
abuse?
Is it necessary to even use medium weight at all? If it is, should I just
use medium weight throughout? Or, if I want to use medium and light weight,
can you put medium weight fabric on the top of the wing and utilize light
weight on the bottom side? The difference in cost between the two is minimal.
Is
there a major difference in weight between the two after covering and
painting? I have been told that the lighter fabric is easier to work with than
the
medium and heavy weights.
The only reason I think I would want heavier fabric on the tail would be for
landing in stalks and heavy weeds on unimproved landing sites.
Having never done this, I feel like I am delving into the dark sciences a
little. I plan on using uncertified dacron and dope, with as few coat as is
practical. I do not want a glass finish, I want the weave to show and would
like four coats, maximum, I think.
I try not to bother the group with trivial questions; please bare with me,
and forgive my ignorance in this matter.
Thanks in advance,

>>The yellow Piet in the "Victoria Piets" file on Mykitplane has eyebolts
and is old enough to have been rebuilt and recovered a number of
years ago. No mention of eyebolt or flight problems.
That doesn't mean the eyebolts will never rotate. It takes an extra 5 minutes
to fix it and the consequences of a locked control surface could be fatal. Some
things can be left to fate but respectfully, I disagree and this is not one
those things.

Looking at the plans again it appears to me that the brace interferes
with the hinge bolts anyway. The block does not have to be very
thick, 1/4" will work fine. If you do decide to go the eyebolt route
the block will be an advantage as the shank doesn't have to go
through the angled brace. It will be in the middle of the block.
Also why would there be much more weight at the end? The bolt
or bolts, depending on the hinge used are only going to be an extra
1/4" long and the block weighs nothing. Another also, the brace wires
attach half way between the two outer hinges ( 11" in from the tip ).
I wish I'd thought of Corky's idea of mounting the hinges beforehand.
Getting nuts down between the gussets will be fun ( crawdads must be
brain food! ). :-)

be very creful with the AN43 eyebolt style hinges. If you do not secure them
so that they can not rotate in the hole you could get a locked up control surface
in flight.
A good way to keep them from rotating is to use the drilled shank version with
a castle nut. instead of putting a cotter pin on it, use a short length of
music wire that has a round loop bent into one end. Slide it through the shank
and use a wood screw through the loop and screw it into lead or trailing edge
spar. It is only necessary to secure one side of the hinge.

I read your E-mail and went downstairs to take a look at my uncovered stab.
Then I came back upstairs and read Clif Dawson's reply. Then I went back
downstairs to take another look at my stab. I would go with #4. Cause #2 would
cause interference with my elevator hinges and # 4 has half as many pieces
to deal with. Also, I used the GN-1 idea for elevator hinges instead of the Piet
idea for hinges. The Piet elevator hinges are more original, but the GN-1
hinges(Eye-bolts) can be purchased thru AS&S.

Subject: | How many ounces does it take |
Hi Max,
I had the same questions, so when I went to the PolyFiber class at SNF last
year, I asked them. They strongly recommended against using the light
fabric for anything but an ultralight. While it is strong enough for a
Piet, they said it would balloon up too much between the ribs and the
stringers.
Of course, I didn't ask about what you are suggesting, but they could have
recommended covering the fuselage with the light stuff if that is
acceptable.
So I followed their advice and used medium weight throughout. it is tough
stuff, and can certainly withstand a lot of abuse from finger-pokin'
onlookers.

Subject: | Re: Need Help on Horizontal Stab - AN43 eyebolt hinges |
When I was toying with the idea of using the eyebolts, my mentor brought up the
issue of them rotating. So I went with hinges that looked original.
I do kind of like the hinges that are just a strap of steel with the ends bent
at a 90. Both hinges together with the hinge pin thru look like a rectangle.
Very clean looking.

Max,
Since the max wing loading and max speed far surpass the Piet, I used the light
fabric. It was the uncertified stuff from AS&S, at about $3.10 per running yard
of 62 inches wide. I worked out perfectly.
Just keep in mind that the thicker fabric holds more paint/dope.
My final empty weight was 595#. And nothing flew off yet!
But then again I don't have any rough terrain/stalks to deal with.

Hi Piets
Hi Dennis
The original plans are for one piece wing, use the suplemental center
seccion so you can get the center point of the semi wing (not the
spar), with this and with the new fittings (long fuselage) the fittings
are inline with the flying struts, double check both ,the one wing plans
and the 3 pieces wing for it, I think that I made on the same way that
Corky.,,

Thanks for the advice and your concern for my safety. I will gladly use
your idea. Now is the perfect time for me to do as you suggest, cause I
am ready for final inspection of the wings. Should be ready for fuselage
and tailfeather inspection within a month.
