Subject: | Stress testing Corvair motor mounts? |
--> Pietenpol-List message posted by: Ben Charvet <bcharvet@bellsouth.net>
Hi All,
I'm building a Pietenpol and have welded up a motor mount per Pietenpol
plans. In WW's book he talks about stress testing the motormount. I'm
not clear if he is talking about new designs, or just to stress test
your particular welding skills. My mount turned out pretty nice, but I'm
far from a professional welder. My mount was welded up right on the
firewall and turned out very true and straight, meaning all the holes
line up easily. I'm curious how many of you have stress tested your
motor mounts. This subject keeps coming to me at 2AM.
I saw the quote "Nature can always find the hidden flaw" somewhere the
other day, and it sure makes you want to pay attention to the details.

Does anyone happen to have an estimate on how many Pietenpols are out there? I
looked in the archives and couldn't find anything. Maybe a search of the FAA registration
website (by someone smarter than me) would give us a clue. Of course
that wouldn't account for all the international Piets.
It would just be interesting to know.
Any ideas?

Subject: | Building logs??? |
Greeting to all,
Well I am about to start building and I was wondering if anyone knows of a builders
logbook for the computer? Also curious what sort of building logs everyone
keeps? Are there particular guidlines of what is needed for records kept and
when I need to have inspections, ect..
So much to learn.
For the record, I have waited several years so that I am 100% certain that I will
complete this project after I start. I noticed an awful large number of builders
that have there work for sale. I wanted to be sure I would not lose interests.
All these years and I am all pumped up...

Welcome, Brian
There are no specific regulations that I know of about building logs,
other than they have to document what work you did yourself to establish
that you meet the 51% requirement for homebuilts. This definitely isn't
a problem for a Pietenpol. I'm just keeping a written log by date of
what I have accomplished. There are software programs available on a
web-based format to purchase, like Kitlog Pro at kitlog.com, or you can
just use the free program on mykitplane.com like I do. Just go to
mykitplane.com and follow the links to builders logs, pietenpol, and
you'll find several builders including me. If you haven't already, get
involved with your local EAA chapter and they can hook you up with a
Technical Advisor that will do periodic inspections along the way (for
free). These are the folks that will keep you out of trouble, as the
FAA only looks at the completed project. Joining the EAA also gives you
access to their homebuilder area on their website that has lots of
useful tips on building, registering, and test-flying your homebuilt. In
reference to the multiple projects for sale, you have to know going in
that this is a long-term project, and people's life situation and
motivations can change over a period of 5-10 years. I'm not retired and
only can work on my project a few hours a week. I've been building
about 1.5 years, and have my fuselage on the landing gear, my motor
mount built, and my wing ribs made. I realistically have at least 3
more years to go. I'm sure others will chime in with the advise to do
something on the project every day, even if it just to sit in the
cockpit for a few minutes making airplane noises. The longer you stay
away, the harder it is to forget where you left off, and the easier for
your priorities in life to readjust.....
Hang in there,
Ben Charvet

Subject: | Stromberg Supplement |
Gents,
I was able to buy an affordable NA-S3A1 at SNF this week. Does anybody have the
Bendix Overhaul Supplement for carb. part # 380174-1? I've got a photocopy
of a supplement for carb # 380174-2, but I don't trust it for my new (old) carb.

Subject: | Torque Tube Pulleys |
Hello all,
I have a question regarding the alignment of the pulleys on the torque tube;
two side by side, and one by the aileron horn. According to the prints, the single
pulley is centered on the tube, and the two rear pulleys are also centered
on the tube.
Are people aligning the single pulley with one of the rear pulleys so they are
aligned and attaching the cable tab on the control arm so it is also aligned
or does it not matter to do this?
Also, depending on how the wing gets located above the fuselage, my aileron cables
(from torque tube horn to spar pulleys) will be at some angle. Have people
found where the optimal location to mount the aileron horn is, or is the dimension
(14-1/2" from pilot seat) on the print just right? I would think if
the horn is too far back, the cables may interfere with the instruments, and
if it's too far forward, the cables may rub on something else.
I'm building a long fuselage, and am getting ready to weld the torque tube. I
do not have the center section built, and the wings mounted. I could weld everything
on the torque tube except the aileron horn and save that until I get
a wing mounted.
Thank you,
John

Hi John,
I offset the front pulley to one side so it was aligned with one of the
rear pulleys. I put a slight z bend into the tabs I welded through the
rear control stick, so the tabs would align with the pulleys. Here is
my picture from mykitplane.com:
http://www.mykitplane.com/Planes/buildLogReportDetail.cfm?BuildLogID=979&PlaneID=481.
I haven't installed my center section yet either, but my control horn is
within an inch or two of the front seatback, so I don't anticipate any
problems with interfering with instruments.

John, take a look at this page: http://www.flysquirrel.net/piets/piets3.html
down where you see a picture of the instrument panel and rear cockpit.
Notice where the horn is located relative to the plywood bulkhead that forms
the back of the passenger seat. If you go much further forward, you'll be
in the plywood bulkhead and framing. If you go much further aft, you'll be
in the instruments. If you go on down on that same page, there is a shot
looking up underneath the instrument panel and you'll see what I mean; that
picture is only showing the two engine instruments, which aren't nearly as
deep as the flight instruments above them. And the last picture on that
page shows a pretty good closeup of the horn on the torque tube. It's
mounted about as far forward as it can go, and that's pretty much where it
needs to be.
"Build it to the plans" unless the plans aren't clear, then just ask and
you'll get answers from some mighty savvy guys here, like Walt Evans, Mike
Cuy, Chuck Gantzer, and others.

Subject: | Re: Torque Tube Pulleys |
I offset my single pulley just slightly to the left and offset the two to the left
so the right pulley is more inline with the cable coming off the stick. There
is a slight angle between the front pulley and the back left pulley, the back
left being further away from centerline then the front. I put the aileron
horn where the plans show it. Never see anyone complain about it being located
as shown on the plans.

Doc Mosher did some extensive research a few years ago, and put out a booklet
he calls 'Pietenpol Owner Directory'. He listed the ones from U.S.A., Great
Britian, Canada, and South Africa. There must be 600 to 800 listed in there.
Really a great little booklet, with lots of pictures, and illustrations. He
was selling them for $5 or $10 bucks, but I don't know if he has any more. He
goes to Brodhead every year, and I think he still monitors this list. He is
a retired Airline Captain...you'll have to let him explain why they call him
'Doc'. He's a great guy to talk with, has a wonderful sense of humor, and
absolutely loves old airplanes, especially the Pietenpol. He once told me my
plane had the most aft C.G. of any Pietenpol he's ever seen...then he pointed to
the last two digits in my N-number. :)
His e-mail is - docshop@TDS.net

Hey all
I was just going thru a new West Marine cataloug. They are what it sounds like,
a boating supply cataloug. They have really increased the line of fuel tanks
they carry. There are several that look like would work for the Piet for the
nose. Here are a couple of examples;
13 gal aluminum 18.5"lx16 3/8"w x 10 3/8"h $189.99
11.5 gal polyeythelene 20"l x 14 1/4"w x 11 1/2" h $129.99
These tanks have fills, pick ups and fuel level senders installed. There are several
pages of tanks and fittings.
They also have online cataloug at www.westmarine.com
