Subject: | pedal return spring |
I've scanned and uploaded a photo of Dan Horton's pedal return spring setup,
at http://www.flysquirrel.net/piets/pedalspring.jpg
You can see the spiral-type spring that holds the pedals in place and
maintains tension on the rudder cables. I thought it was clean and clever.
Also visible in the photo is Dan's heel brake setup. It isn't real clear in
the photo but what he has are small heel brake arms that he fabricated from
aluminum stock, with the braking force transferred from the brake arm to the
actuator arm via a rod or tube that is concentric (inside) the rudder pedal
pivot tube. That puts the brake cables all the way outboard, out of the way
against the inside of the cockpit wall, with a straight shot down to the
mechanical drum brakes.
Not only did Dan's airplane win awards in its "Canuck/Jenny" configuration
after he completed it, but it was again a show winner last year (I believe),
also appearing in a feature story in Sport Aviation after Dan sold it and it
was repainted and marked as a different airplane. Was it a Navy paint
scheme? I'm over the hill now and don't remember too well ;o)

Subject: | Re: Throttle control question |
One other throttle control questions for anyone that has used the standard
throttle lever hanging from the top longeron. Is it necessary to secure the
bracket to the longeron with bolts and nuts or will two wood screws (maybe
with a little epoxy on the threads) be enough?
Thanks
Rick

Hi Gus,
The 1/8" cables between the lift struts are adjustable with turnbuckles.
On NX18235 the outboard ends are attached to the lift strut attach bolts
using a cable pull. The inboard ends are attached to an eyebolt that
also serves as one of the gear leg mounting bolts.

Sorry i'm so late saying thanks for the info on Hem fir. My email went
down after i asked that question and i've been gone since Tuesday with
my work. My little world was just shattered today when my daughter
called and told me she had heard that the road was closed a few miles
south of the airport at Carrollton MO where we keep our Champ. I thought
no big deal because we are quite a ways from it. I got with the Opts
manager at our office where i work out of and told them i needed to get
home to check on my plane (I truck for a living) and they got me in this
evening. I work in Kansas so it was about 9:30 this evening when i got
to Carrollton. I could not believe it-I could'nt even get to the airport
because of the high water. I'm guessing that there is 2 to 3 feet of
water in the hanger. Words can not even begin to express the feelings i
have now-disbelief to anger (at myself). This happened in 93 but was
only supposed to happen every 500 years. I'm a half hour north of the
airport but will go back tomorrow and try to find someone with a boat to
take me out to the airport. Hopefully i can get it up on a makeshift
stand to get the water out of it if it is that deep. I'm so emotionally
down now that i have to taslk to someone and i know this group is the
one to go to even if its only for moral support. Steve Singleton

Subject: RE: Pietenpol-List: Hem fir
Steve,
Not sure, when you say 'Hem Fir", if you are referring to Western
Hemlock. If that's what you mean, then it can be a suitable substitute
for Sitka Spruce (almost identical density, with higher strength). Ask
the lumberyard exactly what species they have on hand. Check the
weblinks that Chris Tracy posted yesterday, and you'll see Western
Hemlock listed in the charts.
Go to the Matronics Archives,
http://www.matronics.com/search/
and do a search in the Pietenpol Archive, using the word "hemlock".
You should find enough reading to keep you busy for a couple of hours.
As you read through, you'll see that at least one builder (Clif Dawson)
has built almost his entire airframe using CAREFULLY SELECTED Western
Hemlock.
I can't recall the source, but I definitely remember reading that BHP
built laminated spars from carefully selected lumberyard Hemlock.

Subject: | Re: Wing flying drag wires? |
Gus
Yes, the wires are VERY important. The vertical loads on the wing are
supported by the two struts. The struts on a Pietenpol are parallel to
each other. This configuration does not resist for and aft loads very
well. The wires take the for and aft loads keeping the struts and wing
from rotating front and back. They are only loaded in tension so wire
works quite well and are lighter then tubing. See attached drawing for
a pictorial description. The same explanation works for the cabain
struts as well as the wing struts.
Some designs, like a cub, angle the rear strut forward to do away with
the wires and take the for and aft loads. This requires a very strong
fitting where all the wing loads are concentrated. Mr. Pietenpol chose
to divide the load into two thus making it safer for the light weight
structure to carry the loads.
