Subject: | Flying NX770CG - Video |
First of all, I would like to thank the many folks who responded about
the first video I made. Your help was extremely valuable in the making of this
final version. This has been a HUGE project for me, but I'm glad I did it.
It's one of those things that seems like it's never done.
I finally finished 'Flying NX770CG', (I'm close to finishing 'Building
NX770CG'). For those that have never seen a Pietenpol fly, or for those who
have never been in one, this video is for you !! I put the viewer in the Pilot
seat to give the sight, sound, and feel of what it's like flying Low & Slow.
It's 1hr 50min long, and here are some of the scenes:
Engine start, taxi, and Detailed take off & landing sequences, with 8 or 9
camera angles.
Some special effects.
Lots of Smokin' scenes.
Air to Air footage.
Background music to accompany many scenes.
Lots of Voice Over, explaining what's going on.
In air video of Cutting the Toilet Paper, Windmills, Lakes, Hot Air Balloons,
Chasing trains, pacing the shadow on the interstate.
Some of my 3100 mile cross country flight in '04.
River Run - down on the deck.
Detailed landing sequence.
$20
e-mail me direct, if you are interested.

Source of AN bolts
I think one of our site members directed us to a good source for inexpensive new AN bolts and other hardware. Take a look at www.airpartsinc.com in Kansas City, KS. While their catalog only shows sizes up to AN6-20 (3/8"-24), an obscure note on p.11 of their 2005 catalog says they stock up to AN10 (5/8" dia.). I would try them for bolts first.
On the subject of hardness, you don't want steel parts that are tempered to great
hardness. I recall dropping a 3 inch dia. tool steel form tool (it made
the shape of a unique part). I had the tool hardened professionally to maximum
(Rockwell) hardness. It shattered on the concrete from a three foot drop.
That's a good argument for not hardening your own stuff, or considering the application
very thoroghly. It was great for my app., but required special handling.
Case hardening the first few thousandths of any bolt can be a good idea, though,
for you don't want the threads to be soft and work against each other. As
pointed out, rolled threads are stronger than cut threads, in part because they
are "work hardened" by the process. I suspect that AN bolts are not only rolled
threads, but may be case hardened, as well.
At a practical level, while all this discussion is worthwhile, I plan to leave
it to the pros and buy AN parts. In a pinch I would not hesitate to use other
quality bolts for a while.
The practice of changing specific bolts annually is a new thought for inexpeienced
me. Is that considered "good practice" or is that someone's (e.g., the
FAA) requirement?

My understanding is that there is hardness and toughness.
I read where AN bolts can be bent into a knot , cold, without breaking. Don't
think a grade 8 will do that.

I think I remember reading in the Sacramento Sky Ranch tech book that AN
bolts have the threads actually pressed into the bolt vs store bought grade
8's that have the threads cut into the bolt shank. Think the tensile,
elongation and hardness are the same but this issue of how the threads are
cut or pressed is critical for failure. Sky Ranch also has a good section
on the amount of torque needed to get the bolt to right elongation for
maximum clamping without overstressing to failure. Recommend this book to
anyone building a homebuilt.

John,
I will try to remember to let you know when it's done, but it probably not be
done before Christmas. I'm going into great detail about the construction.
Ya just can't imiagine how much time it takes me to do this video stuff !! I
will certainly post it to the Matronix Pietenpol Group, when it's done.
