Subject: | Graham Hansen's retired Piet |
Graham,
I found your note about placing in a museum your Pietenpol, your old friend
of so many flights and adventures, both so fitting and very touching. It
reminded me of my own love and memories of beloved old dogs and other
departed family long gone to rest.
Thanks for sharing.
Tim in central Texas

Jake; the difference in weight between your left and right elevators is probably
due to the trim tab, bellcrank, and electric trim actuator servo on one of them.
You do have electric pitch trim on your airplane, coupled to the altitude
hold autopilot, right? (Just kidding)
With that weight difference, it would almost make you wonder if the same wood species
was used for the two pieces or something.

Yep, must be the satcom antenna that makes one side heavy....?!? I'm guessing
it is the wood density as well somehow. It's all a mystery as the left and right
rudders both weigh the same.... :-)

For another data point (or points). Here are the weights of my tail parts.
These are covered and painted. I used Stewart Systems with the
lightweight (uncertified) ceconite, Stewart primer and Benjamin Moore's
Advance for color using the techniques in Malcolm Morrison's slides
(thanks, Malcolm). Control horns and hinges are installed and included in
these measurements:
Vert. Stab 2 lbs 2.2 oz.
Rudder 4 lbs 0.4 oz.
Hor. Stab 7 lbs 10.6 oz.
Elev. 3 lbs 10.6 oz.
Elev. 3 lbs 9.8 oz.
Here are some other weights:
Aileron 5 lbs 11.8 oz. (includes horn, but excludes piano hinge and
hardware)
Aileron 5 lbs 6.2 oz. (includes horn, but excludes piano hinge and hardware)
Flop section 4 lbs 13.8 oz.
Jury struts (vertical pieces are 3/4" thin wall Chromoly round tube with
balsa to streamline, covered with fabric; horizontal pieces are 3/4" thin
wall Chromoly with crimped ends) 1 lb. 12.1 oz, each side.
I haven't yet weighed the center section (which includes an 11 gallon fuel
tank), the diagonal struts (like the jury struts, streamlined with balsa
and covered with fabric), or the wings, which are now covered and painted.
I'll try to weigh those soon.
Cheers, Ken

Here's a head scratcher. When weighing my plane NX929DH right before inspec
tion for flight, left wheel weighed 358 lbs. while the right weighed 339 lb
s. That's quite a difference I would say. What's on that side that is so he
avy? Subtleties in the Ford? At the time I had the side-driven mag on that
side, but that doesn't account for all that weight.Never really figured it
out.

It's a left rudder when I press on the left pedal and it's a right rudder when
I press on the right pedal (ha!). Routing the hinges...

Subject: | coaming and sharp edges |
UNCLASSIFIED
As a friend was looking over my bird he made the following observations. "There
sure are a lot of sharp edged with the aluminum. What happens if you crash?"
Granted he is a nervious nellie who is scared to eat at mom and pop mexican cafes
and will not go point into a windowless bar. BUT does he have a point. As I
am putting this back togather, I know that I will cover the edges with foam and
real simulated leatherette. But the sharp edges could cut straight through
that if I planted my face against it at, Oh lets say 50 MPH!
I have since thought of adding some small hard plastic trim to it. Any other thoughts?
Blue Skies,
Steve D.
