Michael,
Just a quick note to let you know how much I enjoyed your video. Your
work and shop are meticulous. Someone who is just starting their ribs
and jig could certainly benefit from watching it. I liked your delivery
and also think the picture and sound quality is very good. I highly
recommend it.

Jack,
I would have to agree, he is definitely working on a great idea full of
good information and certainly helpful to anyone building ribs. I am certain
that future installments will only improve. I can wait to see the next set of
hints. I would encourage anyone interested in building to order the video, its
well worth the investment in cash and time.
Its pretty neat that we have this type of resource in development and
available. Actually I was interested in doing something similar but was to lazy
and
too much interested in gluing my own sticks together making progress rather
then video.
For the sake of all builders and would be builders I am glad there are
people interested in sharing their knowledge like Mike Perez, Michael Cuy, Chuck
G
and with the rest of us. I hate to say it but I am a sucker for anything
Pietenpol, especially if I can learn from it!

Subject: | Re: Grade 8 bolts |
Dan,
Back when I was buying prop bolts, I did a lot of reading about this.
I read enough to keep me from using anything but AN bolts. Prop bolts
are pretty critical, and consider what would happen if your prop
departs when already in an aft CG position?
Besides, you can get AN bolts from Aircraft Spruce for about $2 each.
I believe they are the same thing as prop bolts, EXCEPT the threaded
portion of the bolt is shorter. For that reason, you have to be very
careful to make sure you don't bottom out the nuts on the non-threaded
area. As long as you get the correct length, it is a non-issue.

You're putting a Model A in it, aren't you Dan? No reason the prop bolts s
hould be any more reliable than the engine.
Just kidding - I don't think stress would be an issue since Grade 8 are sup
ossed to be 150,000 psi tensile strength and AN6 bolts are 125,000. Howeve
r, can you get Grade 8 bolts in a fine thread? I know AN6 bolts are exepns
ive at around $9 each, but there is probably not a more critical bolt on th
e airplane - particularly with a model A, where you typically only have 4 b
olts holding the prop on. I would prefer the fine thread of the AN bolts.
Just my 2 =A2, if it is even worth that much.

Subject: | Re: Grade 8 bolts |
I think when Jack says that Grade 8 bolts are *supposed* to be handle up to
150,000 psi he points out one of the main issues with commercial grade
hardware. There is not the same level of quality control in the production
of commercial grade hardware as there has to be with AN hardware. In
addition AN hardware is produced from a more corrosion resistant alloy, and
is heat-treated. Using commercial grade hardware may be fine in
non-structural applications if you so choose, but I would consider prop
bolts to be "structural" (insofar as being critical to the safe operation o
f
your Piet).
As Steve points out, having the prop depart the aircraft is never a good
thing. Even worse would be if only one or two bolts broke loose, and the
prop shakes things to the point where it departs with the engine attached t
o
it. That would ruin one's day....

John for sharing some of yours with me.

Steve,
Wow- after reading that article I will not use those industrial bolts. But I
checked on the Sensenich web sight and their bolts are way too much- at least
$200.00 with shipping. I think I will take my chances with AN bolts. Its
hard to find the right ones because the threaded length is so short. Thanks.

I put a throttle in the front of mine, along with dual controls (except
brakes and carb heat). I also have basic flight instruments (compass,
airspeed, and altimeter) in the front. If I had known it was going to
come in as heavy as it did, I would probably have skipped the
instruments, but it does make it nice for passengers. I also find that
on long cross countries, without reading glasses on, the instruments in
the front cockpit are easier for me to see than the ones in the back.

Guys:
I finally got my airplane up on the gear and outside for the first time
today. Attached are a couple of photos (if they work) to show the
current state. I ran out of the right sized screws for the elevator
hinges or they would be attached as well.
I would have made a little more progress before photographing, but
yesterday the firewall got away from me and now I have five stitches

I AM going to make Brodhead next year . . . with or without Mikey's

Gene,
Six feet is enough. If I were to do again I would buy hinges that were
3" wide when open. The largest I could get from Aircraft Spruce or
Wicks was 2". McMaster has 3". With the angle of the aileron spar, and
2" hinges, your bolt holes on the aileron side are pretty close to the
bottom edge of the hinge.

Gene,
I accumulated a pile of hinges (at great wasted expense) before I got one I
liked. I went with the extruded type, aluminum. I got a "special quote" from
Mcmaster Carr, because 6 ft. was the longest length listed in their catalog
for that type. They got back to me and I bought two of them 7ft. long. I see
in their catalog that now the standard lengths for some types they offer are 8
ft. I love paging through their catalog.

Good article, and kind of scary. I can't help wondering, though, what
the sainted Mr. P. used to keep prop and hub together. Bet his bolts
didn't come from Sensenich. Probably weren't AN, either, all things

My take is,,Grade 8 bolts are hard.
But AN bolts are tough.
I was enlightened to the fact that a long AN bolt can actually be bent
and twisted into a pretzel shaped knot, without heating, without
breaking.,,,amazing.
My amazing Mentor, which I refer to all the time,,,whitnessed a crash of
a Mooney. He said the thing ground looped, and the tail came around to
meet the nose, but the engine mount bolts (I believe were AN6's {3/8"} )
never broke,,,,Never broke!!!

Subject: Pietenpol-List: Grade 8 bolts
Steve,
Wow- after reading that article I will not use those industrial bolts.
But I checked on the Sensenich web sight and their bolts are way too
much- at least $200.00 with shipping. I think I will take my chances
with AN bolts. Its hard to find the right ones because the threaded
length is so short. Thanks.

Dan. I may be able to help out. I misordered prop bolts (3/8 AN 6)
several times (wrong length) plus changed props (needed new length) and
have kept them just in case. If your interested send me the length you
need and I'll check the next time I go to the hanger.

I think it's a bad idea. I have been around a lot of good quality grade 8's. and
from what experience I have had. they are extremely strong.but extremely brittle.I
have welded them at the head to such things as electric motor brackets
to keep them from turning and they would almost immediately break beside the weld.
i know that is a different use but just to show how they react. also seen
them installed as shear bolts in the drive shaft of a brush hog. once again the
broke right quick where grade 5 were elastic enough they might go for days.
neither a good reason to know for sure whether they will hold up on a prop,but
I think for my money I would much rather run grade 5 than grade 8 unless the
load was specifically in tension. not in shear.Raymond

Gene,
I'm not for certain, but my 2" hinges from Wicks are .051. McMaster's
3" hinges are .60, which would be fine.

In reference to skellytown flyer ":... I think for my money I would much

not in shear.Raymond"
and
Owen Davies: "Good article, and kind of scary. I can't help wondering,
though, what the sainted Mr. P. used to keep prop and hub together. Bet his
bolts didn't come from Sensenich. Probably weren't AN, either, all things
considered."
----------------------------
An excerpt from Chapter 1 of the 1932 Flying & Glider Manual, where the Air
Camper plans were introduced:
"In building your plane, don't be penny wise and pound foolish. You save
very little by substituting inferior lumber for regular airplane spruce, for
example, and your plane won't be nearly so sturdy when built of inferior
stuff. It is best to buy your material from a reliable airplane lumber and
supply house. It may be possible to pick up bargains now and then around
your local airport, and if the bargain is a real one, take advantage of it -
but be sure of what you are getting."
I highly doubt that if you asked those editors from 1932 if the same line of
thinking applies to the hardware you build with, they would say "naw, go
ahead and use whatever is down at Farm and Fleet. It's not that important".
Pietenpol used what was available to him at the various times he built his
aircraft. From non-aircraft grade hardware (we assume), to oatmeal container
cardboard for his leading edge (supposedly), and bedsheets on the tail
feathers (allegedly). He designed a very good aircraft and built them how he
chose too, and got by with it. Steve Wittman was an even more prolific
aircraft designer and racer. He built numerous airplanes, flying them both
for pleasure/utility and air racing, and got by with it. Until, that is, he
failed to properly apply the fabric to his aircraft, and he and his wife
were killed.
Skimp whereever you choose, but be prepared to be bitten in the hind end.
The collective 105 years of aviation experience that is out there has taught
us that there are acceptable, safe ways to do things to mitigate the risk in
our hobby. Building with properly graded acceptable wood is one; building
with aircraft grade hardware is another (unless some circumstance gives you
absolutely no alternative but to use other appropriate hardware). Find your
cost savings somewhere else, please.

I took the front throttle out of Felix the GN-1. Still left the hard rod from the
aft throttle to front of the front pit where it changes to flex cable. If I
was in the front pit and needed to change the throttle I could just grab the
rod and move it, at the same time it would be hard for a passenger to screw up
the throttle setting. That is what caused the demise of the Poplar Piet.

OK, guys, what is the more common, a throttle in the front or not?
