Subject: Pietenpol-List: Elevator cable feel and tension trouble.
I finished my controls and was setting up the loop from the stick to
the reverser and back and I ran into a problem that I and my tech
counselor are both worried about. The system is built according to plans
other than a thin hardwood strip above the cable exit point and a
turnbuckle to adjust tension. When rigged with a tension that feels good
the cable is fairly slack and when you go full stick forward the cable
rises off the front pulley. There is a also a noticeable but not severe
"hump" as the stick transitions backward movement and the cable tension
changes. If I tension it where the cable does not rise off the pulley
moving the stick takes a fair amount of force, the "hump" is very
pronounced and I can't imagine any feedback being felt. Neither of us
has ever seen the piet mechanism in person before I built this one, and
he is a talented RV guy but has limited cable system exposure. I am
stuck between the notion that cables rising off pulleys and such is
unacceptable and that the problems are part of the design and the
reality that Piets have flown for 80 something years with that design.
That would normally tell me I have done something wrong but neither I
nor my tech counselor can find a meaningful deviation or a mistake. Any
ideas?

I would have said that but it sounded self-serving. Certainly, frugal minds
that refuse to pay $10-12 for cable shackles think alike! The pins are a

| Subject: | Re: couple of questions |
If you want the cockpit coaming to be a smooth curve rather than just
running straight down to the longeron, then straight aft, there is a way
to do it. I added a piece of aluminum angle screwed down to the
longeron, which supports a slit piece of 1/2" polyethylene "Funny Pipe"
tubing (available in the lawn irrigation system section of Home Depot),
which in turn is covered by a piece of slit foam pipe insulation, which
then gets wrapped with leather. The aluminum caowling gets inserted
into the slit of the funny pipe and is flush with the top of the angle,
so when you climb in and out of the cockpit, you can put your full
weight on the coaming and it gets transferred to the longeron. Works
very well. The only difficult part was lacing the leather in place,
which required drilling a hole through the aluminum and the angle, then
threading the lacing through all the holes.
Here are some pictures to help explain:
Cockpit Coaming 7 (Large) shows the basic arrangement of aluminum angle,
funny pipe and pipe insulation. The aluminum sheeting for the cowling
is cut to be flush with the top of the angle and the slit in the funny
pipe is then pushed down over the aluminum sheet and the angle, so the
weight gets borne by the funny pipe and is transferred to the angle and
then to the longeron.
Cockpit Coaming 11 (Large) shows the aluminum sheeting in place, with
the funny pipe and the foam pipe insulation installed over it and the
angle.
Cockpit Coaming Leather 2 shows the beginning of trial fitting the
leather over the coaming. Plastic tie wraps were used to hold it in
place as the hole pattern was developed. This was a piece of scrap
leather, and then the pattern was transferred to the final piece. My
wife sewed a nice hem on the edges of the leather before it was laced in
place.
Lacing Cockpit Coaming 1 shows me lacing the leather in place. It would
have been far easier to lace it with a single row of lacing, but I
thought it would look better with a double row. Now that it's done I'm
happy with it, but it was a pain in the butt to do it. Lacing both
cockpits took me about 12 hours of work, and it wasn't fun work.

Gene,
I ended my aluminum about 6 to 8 inches back from the panel. I have the
combing on the aluminum and the longerons. It's really nice to be able
to put all of my weight on the longeron. I have passengers put their
weight on the front cockpit longerons. With aluminum there it may get
crushed.
Can kinda see it here;

Greetings everyone,
I have decided to sell a number of items that came with my GN-1 project.
-30 yds of 2.7oz homebuilders fabric
- 6" matco wheels with disk brakes, master cylinders, 6.00x6 airhawk tires and
tubes
- matco pneumatic tailwheel with J-3 type springs
- older set of Grega plans
- instruments that I would like to sell as a package, includes
airspeed indicator, altimeter, compass, tachometer, oil pressure and oil temp
I have all receipts for the items and they are all essentially new.
I am not really sure what to ask for some of the stuff so contact me off list and
let's talk. Thanks,
Mark Baxter,

| Subject: | Elevator cable feel and tension trouble. |
Scott,
I obsessed about the same thing until I figured out that the weight of the elevator
will take up that forward stick slack cable. As for the hump, just guessing
the turnbuckle may be too tight. Tie a string on the top of the bell crank,
run it back to the tail and tie a small weight on to simulate the weight of the
elevator, now adjust the turnbuckle and you may fix the hump.

The first time I heard of the wire twisting thing , was back when the
Quicksilver U/L's were around. that's how they adjusted rigging, cause
all the wings were wire braced. You took off a fitting bolt, and twisted
it one way to shorten the cable, and the other way to lengthen it.

Group, Well I got to go flying today for about an hour.- About 48-50 degr
ees and a 8-10mph cross wind.- Good day for practice since it's been 3 mo
nths since I flew last.- Corvair ran good except a a couple burps on the
first climb out (got the pucker factor up a bit).- I don't know if it was
carb ice that formed and broke loose as it was pretty humid, or water in t
he fuel, but I circled over the airport for 30 min or so with carb heat on
and off, no more problems.- I thought I thourly drained all the sumps and
the tank was full since I put it away last, and showed no evidence of cont
amination-in the fuel tester.- Oh well, I will take the fuel strainer a
part and clean it up before I fly next, and check the sumps again.- I got
my 5 takeoffs and landings, lazily flying out to the west, land to the eas
t, and got some left and right cross wind ldgs.- Mike did you get as luck
y, and go flying today?-

| Subject: | waiting on parts or refund |
Normally people selling parts have them in stock,or can give you a time that
they will be able to deliver the part that you have paid for in advance as a
lot of us have paid WW in advance by PayPal or check. After that you can't
find out anything by email to them. Still waiting after almost 10 months,I
have asked for a possible ship date or a refund if you aren't going to produce
the goods. I have been totally ignored with no reply so I have to assume this
is WW's way of doing business. I have even ask by email if certain items are
in stock that I would love to have ,No answer. I do not want order some thing
else to have my money tied up for another 10 to 12 months,
This is really discourging when you are trying to build an engine as per
WW's reccomendation using his his proven tested parts.
I am to the point now that I wish I had gone Continental and I would not
have had a problem with parts or part suppliers.

Ted,
I'm sorry you have not had a good experience with WW. In your post you
mention numerous emails that you have sent them. Have you picked up the
phone and given him a call? In my experience (and I have heard others echo
this), you are far more likely to get your issues resolved if you talk to
William on the phone. Emails take less effort and may be more convenient
than phone calls, but I'm sure he gets far too many to answer each one. It
can take plenty of calls to reach him, but I think you will get better
results. Leave messages on the machine as well. Try to keep them concise,
and make sure you clearly speak your name and phone number.
Just out of curiosity how far along are you on your Corvair build/rebuild?
Are the lack of William Wynne conversion parts holding up your progress?

Bill,
Have a good third shift! And congrats on being with a company that needs to
have a third shift. :P
You can search the archives at this address:
http://www.matronics.com/search/
Just pick "Pietenpol" from the Select Archive drop down menu. Read the
instructions to learn how to format your search for optimal results.
The Pietenpol airfoil is the "FC10" airfoil, which is a made up name for a
made up airfoil. As the story goes, Bernard arrived at his airfoil through
experimentation, and gave it that designation because it was the tenth one
he tried, and he used a French curve template to draw it (as far as I have
read).
