Hey Scott,
Stitts has a number of fabric packages for homebuilts and they do have one
for the Pietenpol. It includes all of the fabric, stitching and tapes as w
ell as the chemicals to silver. Check out their website or give them a cal
l. They are in Ohio. Shipping is a little bit costly because of the nature
of the dangerous goods. We have a supplier agent in Toronto so I'm sure t
here must be a network throughout the USA. My guy quoted me $5200.00 Cdn l
ast year which included a single colour.
Best of luck.

Oscar,
I failed to mention that when I am smoking there is a muffled sound to
the engine or at least from the right side where the smoke exits.
I don't see a loss of rpm that I can detect but the pitch of the engine
certainly changes somewhat and I think that is normal. Again in cruise
flight (or preferably a lower pass down the runway "to scare the deer
away") you will know the results of your handiwork better.
PS-- Never admit to doing a buzz job but merely couch it in the terms
mentioned above and if you have no deer in your area just substitute
whatever animal is native to your area: groundhog, prairie dog, Elk,
Moose, Canadian Geese, or penguins. For those down under, slow Koala
bears looking for a tree, Tasmanian Devils, or a pack of hyenas or
kangaroo.

Yes, I can just hear it now. I taxi up to my hangar and shut down after
making a couple of smoking runs. Airport manager comes up to me and asks
what the heck I think I'm doing? "Fumigating for elephants" I'll tell him.
"Elephants? There ain't no elephants around here!" To which I reply, "Well
then, I guess it's working!"
Har, har. Sorry for that bad one.
I know what you mean about the muffled sound when there is smoke in the
pipe, but this was an actual missing/stuttering sound, almost as if smoke
was getting drawn back into the chamber and causing a miss. Regardless, I
think you and Chuck are right and when I operate it at normal flight RPM
with the engine warm, I'll have no problem. I will flight-test it at
altitude before trying it near the ground though. We have plenty of
buzzards around here and I can do an aerial application of "buzzard
dispersant" when the time comes.

Around here our "buzzards" have a fancy name
http://www.scienceviews.com/animals/condor.html
...and are "protected" in such a way that we can't even fly over where they
might live, let alone actually fly over them and spray them with
"dispersant".
Elephants are fair game however.

Actually, our most populous species around here, Cathartes aura (the turkey
vulture), is one of the most inspiring and amazing fliers around. It is
grand to sit and watch them fly and they are really skilful in the air.
They use their tails to maneuver very precisely and their wings are big,
powerful, and provide great lift. They use only minimal flapping to get
airborne or to maneuver since it requires so much "100LL roadkill" to flap
such large wings.
Not the best on the ground, though. Sort of like a taildragger ;o)

Turkey vultures nest and rear young on Vancouver Island
here in BC. When it's time to head south they circle over
Victoria until they have sufficient height( hopefuly anyway)
then launch off towards the Olympic Penninsula. Some
don't make it. Some get part way and realize they aren't
going to make it and turn back. They will glide down until
in ground effect hoping to reach the beaches of Esquimalt.
I've seen them so bone tired that they just plow head first
onto the beach and just lie there. Whatever it is about the
area ( Saanich Peninsula) North of Victoria that makes
them risk their lives and that of their young to get there
is some powerful motivator. Unfortunately they like the
Victoria International Airport. With International flights
from Seattle, the Orient and elsewere, regular flights from
all across Canada, the flying club, lots of training at all
levels, two parachute businesses and highly, world wide
respected repair and restoration companies filling the
air with everything from large jets to warbirds to 152's
using all three runways simultaniously it's a wonder that
these huge birds find it so appealing. In my day (62) it
was spiders and duck hunters. Now the students have
Turkey Vultures. :-)

Congratulations....Chief Oscar "Oil your grass" Zungia..... or how about Chief
Oscar "Baby your wood" Zungia..... tee-hee-hee
Oscar Zuniga <taildrags@hotmail.com> wrote:
Well, 41CC may have a new habit soon. Smoking. I got the test apparatus
hooked up securely enough to allow ground testing. Consisted of an
automotive windshield washer reservoir and pump bungee'd to the side of the
airplane with a small 12V motorcycle battery sitting on that and also lashed
on. Flex hose to the exhaust stack with the last few inches a piece of
copper tubing, to a brass fitting threaded into a boss welded to the stack
just where Mike Cuy said to put it. Two small holes drilled through the
stack wall, again as per Mike's specs for size and location.
One large bottle of baby oil went in the reservoir, engine was started and
warmed up (tail tied to my car's trailer hitch and wheels chocked), then
1500 RPM and I gave it a blip of smoke. Wowza!!!!! She makee smokee! Let
that one waft past the hangar behind me and blipped it again. And again.
And againnnnnn!!!!!!!! Looked back and the hangar was full of smoke, and a
nice trail downwind about an eighth of a mile in the light breeze. Decided
to call it good before the volunteer fire department showed up, since my
apparatus had proven itself.
Couple of things I noticed right away. One: the grass beneath and behind my
airplane was all oily, so was my car parked downwind (tail of the airplane
was tied to it, remember?). So were the gear legs. Maybe when the smoke is
on with the airplane is flying it doesn't oil everything up so bad, but it
consumed 3/4 of the bottle of baby oil and it looked like a good deal of it
was unburned or maybe the smoke condenses.
Second, when I would apply smoke the engine would start to stutter a bit on
that side. It was definitely the smoke doing it. Not sure why, but again-
maybe with higher power settings such as used in flight, it won't do that.
Kind of strange.
It will be nice to get the system complete and operational, but at least I
know that my components will work and the smoke volume should be about right
when the airplane is in flight. I don't know how Chuck "the master of baby
oil" Gantzer does it, pirouetting his airplane in a cloud of smoke. He must
get out of the airplane covered in oil!
Took my brother up for a flight after that and made a pretty decent x-wind
landing. Pietenpols forever!
