Wood shrinkage can allow a through bolt to become loose, all the while the nut
never moving and remaining tightly in place on the bolt.

Tools; great to hear that others are actually torch welding aluminum. on a previous
thread i had mentioned how i planned on welding my tank with a torch, but
didnt want to recommend it to someone just learning since most on the welding
forums seem to claim that its not worth trying.
do you remember what gas and aluminum they were using? i've got acetylene and
5052 aluminum. Sorry for borrowing thread. Paul

Michael,
Very cool, very clean look for your axle cap. One question though- what are you
doing in place of safety wiring the hex nut? What are you doing to keep it from
"backing out"? Just curious.
Did you mill the cap your self?
P.S. Oops. That makes 2 questions.

Joseph, there are many varying views on shoulder harness location and attac
hment points. Look at as many variations as you can and decide what works f
or you. I oped to go with raising the attach point above the turtledeck so
that the harness would not pull down on my shoulders in the event of a sudd
en stop. I built a steel tube frame that attaches to the top longerons that
the harness attaches to, and ran 1/8" cables from the tailwheel attach pla
te to the aft end of that frame to take the load. That additional structure
is covered by a simple aluminum fairing and the whole setup is supposed to
resemble the headrests seen on WWI fighters.
Here are some pics:

Tom,
Take a good look at the prop flange if you are going to use the GPU crank. You
will notice that one of the six bolt holes is drilled off center. It will need
to be re-drilled to to relocate it, I believe the other holes will also need
to be drill to accept the prop bolt bushings. It will work. Dad has converted
several of these for aircraft use. The cylinder are different too. They
are set up for a down draft carburetor whereas an aircraft engine is set up for
updraft. You got those for a very good price and there are many usable parts
in them. Just make sure the parts you choose are compatible.

| Subject: | inter-cylinder baffles |
Hey all,
During some great visits with Gardiner (Thanks my friend for you and your
lovely wife's southern hospitality!), Jeff and Terry, the subject of
inter-cylinder baffling came up.
As I've mentioned, I was hoping not to have to use cooling eyebrows, but my
winter cht temps were too high so I just finished installing some eyebrows.
Do I need to also install some baffling between the cylinders? I don't
think cubs have any, and I think most of the installations I've seen at
Brodhead don't, but I could be wrong.
Would appreciate your input.
Thanks

Well I don't like to tell people what to think or do, but when you read about radiation
exposure levels keep in mind that there is a big difference between standing
next to something which is hot (radioactive) and receiving a dose of rays,
versus having a nuclear isotope lodged in your body nuking those nearby cells
over and over and....
Decide for yourselves.

I agree with John H. that a 65 Continental engine is plenty of power for a
lightly-built Pietenpol Air Camper. If you're
in a very high/hot location then that may not be the case and you may need
more power like the Rick Holland's and
Ken Bickers of Colorado.
If you plan to build a full electric Pietenpol or a GN-1 with lots of goodi
es and extra weight you probably will want to consider more power
like a 75, or up Continental powered engine. (or auto engine of your choic
e). (and a metal prop or a good wood Cloudcars prop that lots
of guys are getting good performance out of on Piets)

| Subject: | inter-cylinder baffles |
Douwe,
I originally did not include the inter-cylinder baffles on my A65. When I
had a stuck piston ring, I sent an email to Harry Fenton, who is the "guru"
for small Continentals. He asked if I had the baffles, and when I said no,
he said that every case he's seen of stuck piston rings was due to high
cylinder head temps, and invariably there was no baffling. He strongly
recommended I add them, which I have done. I think I still have the
drawings he sent me showing how to do it. I'll look for them and send them
to you.

I'd concur Dowe with Jack and Harry Fenton. I believe the Bingelis books s

and they aren't hard to make up of scrap aluminum, springs, and a piece of
welding rod or wire.
I have a set in my airport desk drawer that I have to reinstall this spring

| Subject: | Re: Tore Down my engine! |
Scott,
Thanks for the input! There is a guy here in the Houston area, Dirk Kretschman,
who wrote this article:
http://www.eaa.org/experimenter/articles/2009-04_vp2.asp
and after reading the article, I tracked Dirk down, and got all of the AN manuals
on the engine along with the LAA conversion notes to turn the engine into an
aircraft engine. As I won't be using the PC-60 case, I'm only using part of
the conversion notes.
Like you mentioned, the crank flange does need to be drilled, and the centerline
of one hole needs to be relocated by a small amount. This is clearly described
in the LAA article.
After disassembly, I've found that the crank mikes within the NEW LIMITS shown
in the C & O Series overhaul manuals, and many of the other parts are good, as
well. I've agreed to trade the old PC-60 case and camshaft for a C-90 camshaft,
and so, I'll have nearly a C-90 stuffed into a C-85 case.
If you recall from my first post, along with this stuff, I got 4 chrome plated
O-200 cylinders, which have no detectable wear. Lacking, however, are the intake
manifolds, spider, and several other items. Also needed are pistons and rings.
The C-85 Crankcase that came with the package has some fretting on the center main
flange faces - those adjacent to the bearing bores. MY guess is that I'll
have to send the case out, and have it faced to clean up, then linebored for
mains and camshaft. OR am I overlooking something?
At the moment, I'm cleaning all the parts, and contemplating who or where to send
the case to for repair.
Several months ago, a guy came to me with an aircraft tug that needed repair, which
I completed in trade for two 100 hr. old Slick mags to fit the engine, with
gears and impulse couplings.
So, the list of stuff I have for the engine is growing, but I still need several
items. I'm not sure what's more fun, the engine work, or scrounging for parts...
My total cost to date for the engine stuff is $352.00, not including a
few shipping costs...

because it should cost a lot LESS than buying chemsharp. Couldn't you go
to the local university and buy some from the chem lab? 20 bucks should buy you
enough to last a lifetime. I'm not trying to make you feel bad, I just wish
you would have said something about those numbers before pulling the trigger!

Good job, Mike! Those are the same drawings Harry sent me, that I was
looking for to send to Douwe. Thanks for saving me the trouble.

I'd concur Dowe with Jack and Harry Fenton. I believe the Bingelis books
show diagrams or sketches of those baffles
and they aren't hard to make up of scrap aluminum, springs, and a piece of
welding rod or wire.
I have a set in my airport desk drawer that I have to reinstall this spring.
Thanks for the reminder. (had them out for maintenance)

Here's a good description with sketches on how to make these puppies.

Tom,
I recommend sending your crankcase to Divco to overhaul it. They'll mill
the faces flat, then line bore the crankshaft and camshaft. I had them do
my A65 when I rebuilt it and it has never leaked a drop of oil around the
crankcase seal.
Good luck!

Subject: Pietenpol-List: Re: Tore Down my engine!
Scott,
Thanks for the input! There is a guy here in the Houston area, Dirk
Kretschman, who wrote this article:
http://www.eaa.org/experimenter/articles/2009-04_vp2.asp
and after reading the article, I tracked Dirk down, and got all of the AN
manuals on the engine along with the LAA conversion notes to turn the engine
into an aircraft engine. As I won't be using the PC-60 case, I'm only using
part of the conversion notes.
Like you mentioned, the crank flange does need to be drilled, and the
centerline of one hole needs to be relocated by a small amount. This is
clearly described in the LAA article.
After disassembly, I've found that the crank mikes within the NEW LIMITS
shown in the C & O Series overhaul manuals, and many of the other parts are
good, as well. I've agreed to trade the old PC-60 case and camshaft for a
C-90 camshaft, and so, I'll have nearly a C-90 stuffed into a C-85 case.
If you recall from my first post, along with this stuff, I got 4 chrome
plated O-200 cylinders, which have no detectable wear. Lacking, however,
are the intake manifolds, spider, and several other items. Also needed are
pistons and rings.
The C-85 Crankcase that came with the package has some fretting on the
center main flange faces - those adjacent to the bearing bores. MY guess is
that I'll have to send the case out, and have it faced to clean up, then
linebored for mains and camshaft. OR am I overlooking something?
At the moment, I'm cleaning all the parts, and contemplating who or where to
send the case to for repair.
Several months ago, a guy came to me with an aircraft tug that needed
repair, which I completed in trade for two 100 hr. old Slick mags to fit the
engine, with gears and impulse couplings.
So, the list of stuff I have for the engine is growing, but I still need
several items. I'm not sure what's more fun, the engine work, or
scrounging for parts... My total cost to date for the engine stuff is
$352.00, not including a few shipping costs...

Joseph,
Attached shows how I did my front and pilot pits. Keep in mind this Piet
has not been off the ground.
The 7/16 picture shows the 2nd or 3rd practice instrument board, I have
since moved the engine instruments to the right and the mag switch to the
left, because when starting my Grega I am always standing at the prop or on
the left side.

I like it. I am a BIG believer in Shoulder harnesses.
Much research and discussion on adding shoulder harnesses on the Beech list taught
me the following.
1. There are a lot of deaths and serious head injuries that happen when heads hit
instrument panels.
FAA numbers say using shoulder belts in small aircraft would reduce major injuries
by 88% and fatalities by 20%
2. If you put shoulder attach points too low they add to back compression injuries.
3. One cross chest harness is much better than nothing probably 75 % as good as
a double harness. though you can have torso twisting is an issue.
4. Double harnesses are best, attached just about the level of the base of your
skull. coming straight
5. The setup is as strong as the weakest link.
6. Certified aircraft guys covet the experimental ability to use good quality auto
seatbelts.
It is important enough that the FAA has allowed GA certified aircraft to put seatbelts
in with only a log entry. the only restriction is that the belts themselves
are FAA approved ($) and that they are put in similar to approved setups.
I ended up putting single non retractable shoulder harnesses in my Vtail Bonanza
the same way that shoulder harnesses were put in from 1948 to 1956. The attach
point had become a hangon strap.
Beechcraft Shoulder harnesses were offered as an option in the late 1940s and early
1950s, but Beech dropped them for until the late 1950s because none sold!
No one wanted them. Remember, cars in the 1950s did not have lap belts.
I could not afford the $1500 per seat certified retractable dual shoulder harness.
I will figure out how to mount rear shoulder belts in my Vtail.
I will reinstall the harness in the Piet to get it flying. Then I will evaluate
where it rides on me and pax.
Now I will get off my soap box.
Blue Skies,
Steve D

| Subject: | Re: Axle Threading / TIG Welder sources, rates |
This is a busy thread!
Can't remember the alloy, but they showed oxy/acet as well as oxy/hydrogen? There
were compromises with each, and I leaned towards just oxy/acet because I'm
already set up. If I weren't the hydrogen thing was pretty cool.
I've also played around with alum welding with oxy/acet with the henrob/dillion
torch and that's usually all 1000 series stuff, the advantage over tig being
it's annealed and workable.
The seminar at oshkosh was all standard smith style torch stuff, with a readily
available flux (which may be the same as the propietary henrob stuff, don't really
know).
Ultimately, the real advantage seemed to be that the oxy/acet rig just becomes
MORE versatile knowing how to do it. Like anything, it's a matter of burning
up some gas and aluminum while just learning to assimilate what's happening through
practice.
The most counterintuitive thing was that when things were getting fast, and you
wanted to slow down to let your brain catch up, the natural thing to do is pull
the torch back... WRONG... the heat cone is bigger and you just melt a big
hole. What needs to be done is to feed more filler rod, which cools the puddle
and slows things down. Sounds simple enough...

IMHO BIKIAR
Better than nothing, I would put them as high as is reasonable. To be honest, a
compressed spine is better than dain bramage.
I am going to get mine flying as it was built with them through the upper seat
back. Getting flying is important to me.
Then I will possibly add a turtledeck just high enough to put them where I want
them (and look cool) being safe is also important. This is just added safety.
