Subject: | Cross bracing on a GN-1 |
--> Pietenpol-List message posted by: "Jon Botsford" <botsford7@hot.rr.com>
I bought a GN-1 last fall. I have only flown it about 3 hours (it needed
some engine work and some other small things). The plane has about 60 hours
total on it. Recently when doing an inspection, I realized that the cross
bracing between the lift struts on the right hand side of the passenger
cockpit was missing. Further inspection revealed that it had never been
installed. I have looked at the plans and they do not seem to indicate
these. Question: Is this an optional item or do I need to place the cross
bracing before further flights?
Many thanks for any information that the group can provide,
Jon Botsford

Ted--Bert C. is right on about one of the Bingelis books showing how to
shape the top curve of the firewall. I used that method and all I used
was a small drill bit and tin snips and a rubber mallet. Ok, I guess I
made a 3/4" thick plywood template the exact shape of the firewall with
magic marker spots where the engine mounts poke thru and various cables,
etc. and rounded the edges with some coarse sandpaper and block to give the
1/2" bend some radius. On every hole to that I drilled on any
metal---even those tiny holes where needed to bend the firewall over, I
used a countersink bit by hand on both side of the drill hole for stress
relief / to take out any burs or drill marks. (again as per Tony B's
books.) Sorry...this is more than what you asked.
Mike C.

Subject: | 1932 Flying & Glider Manual |
--> Pietenpol-List message posted by: Ken Rickards <krickards@cvci.com>
I just found my copy of the 1932 Flying & Glider Manual. In on discussion
last week about airfoil shapes I think the opinion of most is that it was a
modified Eiffel. In the manual BP states that he tried many different
shapes, including the Clark Y. He finally settled on a design that Don
Finke , his neighbor, and himself, sketched out one night. He was told by
experts that it was practically an Eiffel 36 with ordinates increased 25%
all along the cord. It also states that the Eiffel 36 was used on the
Curtiss Jenny. I also placed the 2 airfoil shapes from the Piet and the
Gn1, side by side to see the differences. Although basically the same
airfoil shape, there are some differences in the construction and leading
edge shape, as well as the placement of the leading edge spar. If anyone
wants to see this I can email it to them.
Another interesting piece in the manual talks about the spars. It says" the
wings are built up the regular way. Spars are built first( no dihedral,
clotilde). does anyone know what clotilde is? I couldn't find any reference
to the word on the net.

Clotilde is a girls name, in spanish.
Maybe is something they used to say at that time, like "see you later
aligator" or something like that...

Ken,
Clotilde, as Gary says, is a girl's name. It has no aeronautical
significance in the F & G Manual article.
Although the article is purportedly written by B.H. Pietenpol, I suspect
that Weston (Westy) Farmer
had a hand in it since the writing style does not seem to be consistent with
the speaking style of BHP.
(My friend and I visited Bernard on our way home from Oshkosh, August 4,
1982. He had a great
sense of humor, in spite having a painful hip, but somehow the text of that
article just doesn't sound
like him. We will always treasure the memory of that visit with BHP.)
Westy Farmer, I believe, was editor of the publication and no doubt would
have had input regarding
the Pietenpol article. Maybe he knew someone named Clotilde???

Hello, folks;
A buddy lost his Tri-Pacer in a non-flying ground incident and is looking to
replace it ASAP. One of the airplanes he's looking at is in Guthrie, OK and
he only has verbal info and photos of it, so I'm trying to help find someone
reliable who might be able to actually eyeball the airplane for a second
opinion. Any of you good Pieters near Guthrie? Email me off-net; thanks.

Dan,
Think you are talking about a metal "shrinker" neat tool that actually
grabs the metal and pushes it together to make that section shorter. The
"jaws" are about 1" deep, to kind of work on a flange or angle piece to
curve it.
Have it on loan from my mentor.

Walt,
Sounds right, I just couldn't figure out how to spell "shinker", so I looked
it up in a Wag Aero catalog and it said stretcher.
PS these guys talking about Tony Bingels way must have never seen the nice
job a shinker will do. However I do realize the tool is expensive, and
hacksaws, and drills are not making Tony's way a little more feasible for
most.
