Les, Thanks for your imput. I am going to open up the carb (stromberg)
today and look things over. I have had three different carbs on and they all
do
the same thing. I have plenty of fuel flow to the carb, When I frst start
it up it seems to get into the higher rpms which might be bowl gas but then
dies unless I just idle. I have parts ordered for a marvel Shebler
(venturi) but are slow in coming if they do. Thanks again Ken Conrad in warm

I used to do spins in the Ford powered Piets all the time...I once spun down
from 5000 feet to 1000 feet over White Bear Lake...lost track of the turns.
Make sure the CG is not aft of 20 inches, and be carefull if the airplane is a
short fuselage model with a lighter engine up front...usually these ships have
the wing moved back, making the nose quite long, and usually the landing gear
is covered, compounding the problem of too much area out front. Bernard
never wanted us to cover the gear legs unless the airplane had a long fuselage,
for better spin recovery.

The non-metal needle has been suspected of causing problems in the Stromberg
carb when auto-gas is used. The additives MTBE and TAME seem to affect (swell)
the needle. This has not seemed to be a problem when using aviation gasoline
(100LL) having a greater purity and far less additives.
I through away my plastic needle and went with steel.

I have found that small plastic squeeze bottles (4 to 8 oz?) work very well.
The kind I use have a snap-on cap that is attached to the bottle so you can't
lose it.
I invested in a small digital scale (iBal 201) and mix the West System epoxy
by weight. These scales cost about $100, are used by ammo reloaders, and weigh
to .01 gram. They have a capacity of 200 grams. I typically only use 5 to
10 grams. Just put in the resin, get the weight, multiply by 1.2, and add hardener
up to that value. Its very accurate and repeatable for small amounts.
(I can't help it if I'm an engineer!)
BTW epoxy has a very long shelf life. Especially if you keep it sealed in the
can. By using the squeeze bottles, you don't have to open the can very often.

Subject: | Re: Safety? Fiberglass gas tanks & Static Electricity |
Why not add a piece of stainless welding rod to your glass tank when you build
it running from the low point to a spot a couple of inches from the filler cap
so it would come through the covering? Label the end of the wire as the tank
ground and clip to the protruding wire when you refuel (BEFORE you remove the
cap!).
On the plastic fuel cans I designed a grounding kit a few years ago that used an
R/C model fuel stopper with a piece of stainless welding rod through it that
was put through a hole drilled in the plastic can and tightened. The rubber
stopper expands in the hole when you tighten the screw and the SS wire is submerged
in the fuel. If the wire is bent so it goes close to the outlet hole it
stays submerged when pouring. Just ground the can to the fuel tank ground and
on to "earth" and you should be all set.

Subject: Pietenpol-List: Safety? Fiberglass gas tanks & Static Electricity
I've successfully dissipated and prevented static electricity in photographic
labs for many years by mixing Downey Fabric Softener to water at a 50/50 mix,
and then spraying carpeted areas in and around the lab. Here in the Southwest,
on a cold-dry winter day, we can darned near arc weld with static after walking
around on a dry surface and many rolls of films have been ruined when spooling
film out of cassette in a darkroom. The static can bee seen on the film after
development. The Downey/water method nearly eliminates the ionic charge,
thus the reason your socks don't cling after coming out of the dryer when treated
with Downey. (Ask any woman who wears nylon stockings... Downey is a must
on man-made textiles.)
When fueling my Cherokee in the boondocks, I've also used my "formula" for spraying
down the surface of the wings, gas caps, my shoes and the area where I
stand when transferring the gas, prior to fueling an airplane with plastic cans.
(The cans are sprayed before fueling as well and allowed a minute or so to
dry... The back of the vehicle is also sprayed before loading a plastic can! Try
gassing an airplane at the landing strip in/at Wall Drug Store in South Dakota...
ain't gonna happen unless you go into town for mogas. Also, Custer's Last
Stand! No gas at the field, but a convenience store 1 mile away...
Sorry, but sometimes remote fueling is an evil necessity for us who live and
fly off of fields not having a fuel source, such as a ranch or in places in the
Dakotas That's why I always carried my small spray bottle of Downy/Water in
my airplane.
I'm more concerned about fiberglass gas tanks in my Pietenpol though. Fiberglass
makes for a great attractant for static electricity! I wonder if there is
an additional way to enhance safety when adding gas to a wooden airplane having
fiberglass tanks? I'm about to build my fiberglass gas tank and I thought of
adding a small copper wire to the aluminum filler neck, then to the weldable
flange, running the wire down to a low spot on the fuselage where I could connect
to a ground source (probably a small copper shaft driven into the ground...)
Obviously it's wise to AVOID using plastic cans for fueling an airplane, but
sometimes we don't have a choice.
Does anybody have any information about grounding tips and way to avoid static
when fueling a wooden airplane having a fiberglass tank in the boondocks?
Thanks,

have never done that, actually. And precision scales are handy to have for
weighing epoxy resin and hardener. That's why I bought mine. I thought $100
(a little more with the RS-232 option) was really a great price for the
accuracy they give. Mine have the RS-232 option so it can be connected to a
computer. I have written a little computer program to multiply by 1.2 so I can
push one button and have the target weight for the hardener. I'm not sure
about the place I got it. I had to do some repair work on it as soon as it
arrived. They would not pay shipping either way if I returned it.

--> Pietenpol-List message posted by: "gbowen@ptialaska.net" <gbowen@ptialaska.net>
Oh soooo brave, to do spins in a Piete, it'd scare me to death.
On secondary subject of long fuselages and CG's. I just completed the CG
stuff on the rebuild of Piete N-1033B. This plane was built by Dick Greide
back in 1979 and crashed in a MO cornfield in 1996 on the way back from
Oshkosh, due to engine failure. Because the wings were off of an Aeronca
1300 payload, and Greide moved the wings back, longer 4130 fuselage, I
decided to utilize the full advantage of this planes payload abilities by
putting on an o-235 100 hp and shifting the CG as needed to fly my 280 lbs,
plus wife's 130 lbs. Had to move the pilot's rudder petals forward about 4"
due to 6'4" and long legs. It's a cozy fit by all measurement standards.
Here's how the numbers came out: LE of wing used as datum point.
1) gear axles 2"
2) empty CG 5.5" with wt of 680#
3) fuel at negative 12"
4) tail wheel at 161" (had wt of 14 lbs when longerons level, min fuel,
with full tank the bird will fall on nose without lead on tailwheel)
5) Passenger's front seat moment was 20"
6) Pilot's back seat moment was 53"
Using 20% of chord as forward CG min. limit or 12" back from datum, and 33%
of chord as aft loaded max. CG limit or 20". Trial (paper) loaded weight
and balance came out as follows: 1) 170# passenger, 300# pilot, 120 #
fuel. The initial takeoff CG was 17" behind LE, after burning off all but
about 2 gal of fuel, CG moved back to 19". Both in the operational window,
but wouldn't want to do a couple spins, pilot may wantta lose a couple Big
Macs too..
Minimum pilot weight without supplimental weights in tail or baggage rack
is about 150# with full fuel. This depends on the elevator's authority to
hold the nose up during flare
Max pilot weight with min. 2 fuel is about 305#. Moral of story, it is
possible to build a fat boy's Piete, hope this info is helpful for the
other couple non-FAA standard 170#'ers out there. Hope to be airborne next
week or two.

Gordon,
If I read you e-mail correctly, you have wings off of an Aronca on your
Pietenpol. If this is true, then you CAN NOT use the 33% of chord as the aft
loaded max. The 33% aft limit (or as BHP listed it as 1/3 of the wing chord),
is
for the Pietenpol Airfoil...not the Aronca Airfoil. You MUST use the CG range
of the Aronca Airfoil, which probably has an aft limit of no more than 30%.
Loading in an aft CG range is where you will be in serious trouble if you enter
a spin. On several occasions I've seen Radio Controlled Model Planes spin
all the way to the ground, because they were intentionally loaded with an aft
CG, in an effort to attain a sensitive pitch control.

True...Very True !!
On Friday evening, I was doing some 'Smoke Runs' around Cook Airfield, and
someone called the Fire Department, reporting a plane that was smoking, and
going to crash. Luckily, two airport guys were there when the Fire Department
showed up, and they pointed up at my plane as I flew past, and let them know
about my smoke system. I guess I'll have to let the Fire Department know when
I'll be 'Blowing Smoke' !!

Normally, the fuel valve is NOT placed on the engine side. In case of fire, you
want to be able to turn is off. Fire will damage the valve and you might not
be able to turn it off so the tank continues to feed the fire.

Chuck,
I hope to never even approach within 2" of the aft limit on these wings,
for safety reason. But, the Aeronca has a straight constant chord of 60"
like most of the storebought tail draggers, and a lot of tricycle geared
planes. The limits of 33% of chord aft CG and 20% of chord forward CG
limit has nothing to do with Pietes or Aeroncas, these are standard
percentages used since the first Piper's and T-Crafts, due to the standard
shape of the wing. Look at any oldtime builders book, use to be available
from EAA bookstore, on how to build wooden homebuilt plane, these old books
always used the 33% and 20% rule of thumb numbers due to the shape and
chord of the wings they were building. Some designers recommended 32%,
like the Osprey, others like Rutan had other numbers due to the sweep of
wing and the constantly changing chord. For safety reasons, each
homebuilder (aka Test Pilot), has to understand CG limits and how to safely
experiment with their homebuilt wings and, if feasible, expand the safe CG
envelope.
The purpose of my prior email was to let a few of the other Big Mac
challenged potential builders/lurkers know, it's possible to build a
quasi-plans Piete that will safely handle their weights, if adequate
attention is paid to placement of stuff that affect CG. Plus moving the
wings LE back to approx. 18" behind the firewall.
Gordon Bowen
P.S. I stand corrected, I provided the approx. ARMS of the moveable stuff,
not moment. Also N-1033B has a GM starter motor hanging out there by the
prop and a 20lb battery between the passengers legs.

Hank,
They're welcome to come and see me. Looks like they'll be coming to see you too,
now that you've used those key words! This is "The home of the free .....
" isn't it? Its perfectly legal to reload shells, as far as I know. I have
never done that, actually. And precision scales are handy to have for weighing
epoxy resin and hardener. That's why I bought mine. I thought $100 (a little
more with the RS-232 option) was really a great price for the accuracy they
give. Mine have the RS-232 option so it can be connected to a computer. I have
written a little computer program to multiply by 1.2 so I can push one button
and have the target weight for the hardener. I'm not sure about the place
I got it. I had to do some repair work on it as soon as it arrived. They would
not pay shipping either way if I returned it.
I'm not real sure how critical the 5:1 ratio is with West Systems, but I don't
know of a more accruate way to mix than this.

Being into WW-I aircraft and guns as well as getting on the web on several other

the ATF and FBI really DO watch for key words in e-mailed and when ordering
materials. One that draws attention really fast is precision scales (great for
mixing explosives and drugs). Don't be surprised or upset if you find yourself
answering a knock at the door from someone yelling "ATF!, open the door!"
and by all means remember, it is NOT a delivery! ;-)

I have found that small plastic squeeze bottles (4 to 8 oz?) work very well. The
kind I use have a snap-on cap that is attached to the bottle so you can't lose
it.
I invested in a small digital scale (iBal 201) and mix the West System epoxy by
weight. These scales cost about $100, are used by ammo reloaders, and weigh
to .01 gram. They have a capacity of 200 grams. I typically only use 5 to 10
grams. Just put in the resin, get the weight, multiply by 1.2, and add hardener
up to that value. Its very accurate and repeatable for small amounts. (I
can't help it if I'm an engineer!)
BTW epoxy has a very long shelf life. Especially if you keep it sealed in the
can. By using the squeeze bottles, you don't have to open the can very often.

Actually, if all of us self styled engineers want to get it right...as
Bernard said, we are moving the fuselage forward, not the wing back...the wing
stays
right where it is.

Normally, the fuel valve is NOT placed on the engine side. In case of fire,
you want to be able to turn is off. Fire will damage the valve and you might
not be able to turn it off so the tank continues to feed the fire.

Subject: Pietenpol-List: Fuel cut-off valve
Pieters,
Am to relocate my fuel valve from under tank, center. Does anyone know of any
rule, objection to locating this valve on the engine side of the firewall?
give me your thoughts on this subject, please
Corky
Corky,
I located my cable operated, 3/8" fuel shut-off ball valve on the engine
side of the firewall, before I realized that certified aircraft must be
located behind the firewall, for reasons stated by Cy. My reasoning was that I
didn't want any fuel connections in the cockpit, where leaks could possibly
develop. I now have a plan in the works to retrofit a stainless steel box
enclosure, to capture the fuel shut-off valve, and carry a drain in the box overboard,
to the belly. I cannot relocate the valve behind the firewall, because I
built a blister in the tank outlet, to protrude thru the firewall, where the
weldable fitting is glassed in. Any ideas about this retrofit would be greatly
appreciated.
This brings up another question about fire hazards...How much heat is
required for Baby Oil to burn ? I have the fiberglass smoke tank located on the
engine side of the firewall, however my exhaust pipes go down & aft slightly,
totally outside the cowling.

Chuck,
I hope to never even approach within 2" of the aft limit on these wings,
for safety reason. But, the Aeronca has a straight constant chord of 60"
like most of the storebought tail draggers, and a lot of tricycle geared
planes. The limits of 33% of chord aft CG and 20% of chord forward CG
limit has nothing to do with Pietes or Aeroncas, these are standard
percentages used since the first Piper's and T-Crafts, due to the standard
shape of the wing. Look at any oldtime builders book, use to be available
from EAA bookstore, on how to build wooden homebuilt plane, these old books
always used the 33% and 20% rule of thumb numbers due to the shape and
chord of the wings they were building. Some designers recommended 32%,
like the Osprey, others like Rutan had other numbers due to the sweep of
wing and the constantly changing chord. For safety reasons, each
homebuilder (aka Test Pilot), has to understand CG limits and how to safely
experiment with their homebuilt wings and, if feasible, expand the safe CG
envelope.
Gordon,
I wasn't aware of those other airfoils with 33% aft CG limits. I thought the
Pietenpol's undercambered airfoil could get away with it, because of such a
high negative pitching moment. A flat bottom airfoil does not have as much
negative pitching moment (nose down) as an undercambered airfoil.
Chuck G.
p.s. the Wittman Tailwind has somewhat of a semi-semetrical airfoil, and has
an aft CG limit of 28%.

Has anyone tried to log onto the EAA website this
weekend? I have tried all day Sat and all day today
(Sunday)...no luck.
Also, if anyone of you have the FAA N number query
page stored as a "favorite"...would you try to use
that. I have been "denied access"....
All other websites I visit work fine so I don't think
it is my computer......
thanks in advance

Larry,
The EAA site is working fine for me. It looks like the FAA redesigned
their site, this link should get you to the N number lookup.
