Thanks or all the responses about covering. When I planned on going o the EE
A Fabric workshop, I did not realize they would only be speaking about the P
oly-Fiber system. I felt a little bad about being there and knowing I would
not be using their system. When he said their Poly-tak required the two par

t is bad enough just varnishing the damn wings.
Hope to meet up with Gary this weekend.

Subject: | Glue and Varnish Test |
From: | "dgaldrich" <dgaldrich(at)embarqmail.com> |
Several days ago, I revealed that I had "dunked" my ribs in varnish. Someone pointed
out that the varnish might pose a problem with future glue. In order to
determine whether I'd have to sand all the nose portions of the ribs, I did
an experiment, or rather two.
I had some turtle deck stringers that were varnished and almost 1/4 inch thick
-- .220-.245 inch -- that were laying around so I ripped them into 1/2 inch pseudo
cap strips and glued 6 inches of them to a piece of 1/4 okoume plywood.
That length was chosen to approximate the amount of rib that would be glued to
the plywood leading edge. Since I had some mixed up, I used West System epoxy
as well as T-88. Glued 3 each for a total of 6. Also had some douglas fir
that was approximately .285 thick so I ripped some of that into 1/2 inch strips
and also glued them to the same piece of 1/4. After the glue had cured for
24 hours, I marked the sticks at 6 inches out from the plywood, put the plywood
in a vice and hung a water bucket at the 6 inch mark.
I chose this particular test, rather than a tension or compression arrangement
with the thought that the primary strain on the glue joint would be a side load
on the nose part of the rib where it's nominally glued to the leading edge plywood.
After hanging the water bucket on the cap strip, I added water to it until the
wood or joint failed and then weighed the bucket on a bathroom scale. Did it
for the twelve samples and the results are pictured below. ALL of the test pieces
failed in the same manner. They all broke at the "hinge" point where the
cap strip met the plywood. NONE of the glue joints failed.
Conclusion: Since this was more of a qualitative experiment than a serious quantitative
one, the primary one that I reached is that a T-88/West System glue
joint with varnished wood is strong enough for the intended purpose and I don't
have to sand off my ribs.
Observations: The Douglas fir pieces were approximately 25 percent thicker than
the Sitka and yet failed at an average of 70 percent higher load. This lends
credence to the AC 43-13 note that Douglas is stronger and those that use it
could probably use slightly thinner longerons and diagonals in the fuselage.
Notes: This test was for ONE failure mode and the data samples were not tightly
grouped so the quantitative reliability is not very accurate and any calculations
should be based on much more rigorous testing. Since the glue joints did
not fail, this is confirmation that West System is suitable for at least this
sort of application.
Pictures: Glue 1 is the board before testing. Glue 2 is the varnished pieces
after failure. Glue 3 is the Douglas fir pieces after failure. The numbers are
the weights at failure.

I believe it would be a mistake to proceed with your project based on these results.
My understanding is that although a strong bond may appear to have been
made, the epoxy has adhered to the varnish and not the wood. Varnish will eventually
break down as the moisture content of your wood changes seasonally and
the wood expands and contracts because of it. Time will weaken the joint.
Have you checked with the manufacturer about these tests?

What needs to be glued to the ribs after you have varnished them? The leading
edge sheeting or the leading edge itself?
I can't see any reason why you would have a problem. I'd sand any portion of the
rib that needs glued for some key, and then wouldn't worry about it.
My dad dipped all his ribs just like you did on his Hatz, no problems. It's a
similar wing.

I forgot to mention that the varnish on the wood was 12 years old and was taken
from a previously flying airplane. With a great deal of difficulty, I pried
off the pieces that remained on the plywood. None exhibited the failure mode
you're describing. I've redone some 90 year old varnished furniture (I grant
you not SPAR varnish) that was not giving up without a serious fight. The point
is properly applied varnish of most any kind is a b++++ to get off.
I think for use on the leading edge plywood, this is not an unreasonable test.
This ends up being a low stress joint in any event due to: 1) the fact that all
the ribs will be held parallel by a combination of the drag/antidrag wires
and the fabric rib lacing and 2) there is very little, if any, "side load" from
aerodynamic forces.
As a reference to the amount of stress on leading edge fairing, take a look at
Aeronca Chiefs and Champs. Their leading edges are .016 or .020 aluminum held
on by a relatively small number of short wood screws.
Please note that I am NOT recommending using varnish under glue for anything structural.
What I am suggesting is that the dunking technique DOES insure that
the entire rib, even the nooks and crannies behind the gussets, is varnished
and protected from moisture. The "conventional wisdom" that you can't or shouldn't
use glue on varnished surfaces may NOT apply to this specific kind of stress
with these specific epoxies.
That's what experimentation is for and why I offered this data.

I agree with you. Epoxy is recommended to glue all sorts of non porous things
together, don't know why wood with the grain sealed would be any different. Key
is the key, needs to be sanded some is all.
I've never seen varnish release due to seasonal movement. I do believe some very
old varnishes eventually oxidize to the point they flake off, just like the
paint on old machines.
Varnish being spar or not shouldn't have anything to do with it's ability to hold
either, spar varnish means that it's got UV inhibitors is all.
I like the idea of dipping the ribs because of the difficulty of ensuring you've
painted all the surfaces. It's EASY to miss places.

Hi Steve from Owings,
I just had a look through your construction web site (www.mypiet.com) and it is full of great detail.
The one which caught my eye was the Cable Configuration Thoughts and in particular
the slides showing the elevator cable configurations.
I must agree with you that Setup B is the one to aim for to avoid those loose cables
we hear about on flying examples.
The key there is ensuring that from the control column all the way to the control
horns, everything is symmetrical.
By symmetrical, I mean in the neutral position, the control column, idler bar and
control horns are vertical or at the same angle from vertical AND the cable
connection points on each of those items are equidistant from the pivot point.
By equidistant I don't mean that all three items have to have the cable attached
at the same measurement, they can be different, but for each item the cable
should be the same measurement from the pivot point. Does that make sense?
This is why setup B works.
The same would apply to all the cable controlled surfaces.
Symmetry is good! When moving things are symmetrical, they move together in harmony
and all is good.
Hope this information is found to be useful.
Best regards,
John Woods

I Like the dipping idea too. But if the desire to
have bare wood for gluing is there then simply
cover those areas with a bit of masking tape.
Remove that after taking the rib from the tank.
Spar varnish is more than UVinhibitors. That's
a modern idea. Traditionaly this varnish was

Today I slipped another dawn patrol in. Got to the airport about nine, temp
was around 40, but the winds were perfect (calm) so I suited up. Did five
take offs and landings and only landed high once, but no biggie; just tap
the throttle, keep the stick back, keep her straight and she tracks true.
Proceeded to patrol the lines but no Huns showed their faces, all clear.
Patrolled over the house, waved to the wife and proceed to wake up my friend
at his house a few miles up the road before returning to base. Good
landing. She runs rich because. it's a continental and the long pipes make
it run even richer AND my engine guy doesn't want me to lean her out until
25 hours, so I've invested in rags and cleaner because with those really
cool long pipes.. The stuff gets all over the fuselage and tail. Yuck!! Oh
well..Coolness trumps practicality sometimes!!!!!
Nice still day so I think I got some good gps readings.
Cruise at 2200 is around 70.
2400 seems to produce around 75.
2000 is 65ish, maybe a bit less.
2000 to 2200 is FUN. the engine just purrs along sipping the gas, she trims
out nicely and just chugs along very quietly.
It was cold so she climbed REALLY well, my gps vertical climb indicator was
reading between 600 and 750fpm on a totally normal climb-out, so I decided
to actually try a steep(ish) climb and got a steady 1,000. I believe the
gps is accurate, but attribute those high numbers to the cold, the big
C-90/cloudcar prop combo up front, combined with little fuel and me only
weighing 160 all clothed up.
Keep building, it's worth it!

Subject: Pietenpol-List: dawn patrol
Today I slipped another dawn patrol in. Got to theairport about nine, temp
was around 40, but the winds were perfect (calm) so Isuited up. Did five
take offs and landings and only landed high once, butno biggie; just tap th
e throttle, keep the stick back, keep her straight andshe tracks true.
Proceeded to patrol the lines but no Huns showed theirfaces, all clear. Pa
trolled over the house, waved to the wife and proceedto wake up my friend a
t his house a few miles up the road before returning tobase. Good landing.
She runs rich because it=99s a continentaland the long pip
es make it run even richer AND my engine guy doesn=99t wantme to lean
her out until 25 hours, so I=99ve invested in rags and cleanerbecaus
e with those really cool long pipes. The stuff gets all over thefu
selage and tail. Yuck!! Oh well.Coolness trumps practicalitysomet
imes!!!!!
Nice still day so I think I got some good gps readings.
Cruise at 2200 is around 70.
2400 seems to produce around 75.
2000 is 65ish, maybe a bit less.
2000 to 2200 is FUN the engine just purrs alongsipping the gas, sh
e trims out nicely and just chugs along very quietly.
It was cold so she climbed REALLY well, my gps verticalclimb indicator was
reading between 600 and 750fpm on a totally normalclimb-out, so I decided t
o actually try a steep(ish) climb and got a steady1,000. I believe the gps
is accurate, but attribute those high numbers tothe cold, the big C-90/clo
udcar prop combo up front, combined with little fuel andme only weighing 16
0 all clothed up.
Keep building, it=99s worth it!

What is the bump (stalactite?) hanging down from the wing above your head in
the cockpit picture? Is that some type of fuel gage at the bump where the
fuel line exits the wing?

Have you read the newest EAA rag? It has a great article regarding Hangar etiquette.
It's like they have been following me around or or spying on us at our
airport. Great read and right on the mark.
Happy landings all,

Hey all!
I'm thinking of getting a SPOT satellite locator, but wanted to see if
anyone had experience with some of the others out there now before I commit.
Thanks!

Exactly... while I really enjoy visiting with the people around the airport, the
worst is when I get up in the morning and decide that it is so nice out that
I'll take a day off. Something about taking a day of vacation (and the nice
wx) seems to bring ALL of the retired folks out. Ha! A bitter sweet deal as
I really do enjoy my neighbors.
I've often considered posting the Burt Rutan rule (I think it was Burt)... If you
have been here more than 7 minutes and you don't have a tool in your hand,
it's time to go.

Mark; I am scheduled to be in San Luis Obispo on Thursday, June 13 for my culminating
presentation. Commencement is that Saturday, but I don't plan to "walk".
Steve: sad to say, but MFR is an international airport of entry, so we have the
chain-link fence with "bob war" on top, gates with prox card entry, roving guards,
and no fooling around on the airport grounds like at 8T8. Yes, there are
retired guys and snoopers around from time to time, but it's hard to even find
somebody to help me flip a wing or load/unload anything. I have a mighty fine,
clean, new, insulated, lighted hangar so no complaints, but I do miss having
a few like-minded folks around. There are definitely no walk-ups interrupting
me and asking questions. They mythical teenager peering through the fence
just waiting to wash airplanes in exchange for a ride would get arrested and
questioned as a potential terrorist nowadays, I'm afraid.

Subject: | Question about Continetal Engine Mount |
All
I have a question about the plans for the continental engine mount. The 4
mounting points on the engine side of the mount call for "Ream for 7/16 inch
bolts". According to my continental overhaul manual, the mounting bolts for
the A series is a 3/8 inch bolt. Also, in one of the Bengalis' books it
shows a 3/8th inch bolt.
So, what size do I make the hole for the bolts on the engine mount?

Hey Chris,
What you're seeing is a faired housing for a "DG type" compass.
I actually have two similar "sumps" (you can just see the rear one) on the
bottom of my tank that are pretty big too because I'm freaky about fuel
starvation and wanted sumps large enough to really hold some fuel at any
attitude.
They and the compass housing are each made from half an old Soviet aluminum
canteen, cheap and nicely shaped for the purpose.

When my parents lived across the street from us I used to go help him in the yard
on Saturdays. His neighbor always seemed to come over and wanted to talk, every
job took twice as long. One day we put him on the other end of a crosscut
saw cutting a 3 foot diameter oak tree up and we turned around and he was gone!
Moral of the story, give them a dirty job and they will not stay too long.
If they keep working offer to buy lunch, you have some good help.
