Hi everyone,
The last week has been productive and I have my plane all together and
rigged. I have the covering material and will start after the New Year. Just
a couple pictures, if I can add them.

That's correct, casein glue is also known as milk glue and uses proteins found
in milk, very different from plastic resin glue.
The FAA approves glue that meets a mil spec for bonding, for awhile it was thought
that T-88 met this rule, but it was discovered that the mil spec for T-88
was for bonding metal, so didn't apply. I've been told that right now resourcinol
is the only glue that is FAA approved.
Lots of Pitts and aerobatic builders have used T-88 and West System epoxy, and
in fact the FAA has approved it on standard category aircraft in some case-by-case
situations. The new Wacos that are built in Michigan are built with FAA
approval for West System epoxy, but the FAA won't allow this as an approval basis
for other individual aircraft.
As already mentioned, there is little financial incentive for the manufacturers
to go through the FAA approval process, and the FAA is stuck in the 1950s on
this kind of thing, and has bigger fish to fry.
Of course for experimental aircraft you can use epoxy all you want. I like the
West System epoxy best.

I know everyone knows this but MIL SPEC (military specification) does not
mean a higher standard. It just means a standard.
MIL SPEC is Standardization beneficial in achieving interoperability,
ensuring products meet certain requirements, commonality, reliability, total
cost of ownership, compatibility with logistics systems, and similar
defense-related objectives.
In common jargon. A mil spec simply means that this object or substance or
electronic device will perform up to a standard set forth by the military.
IE, This glue will stick these two things together under the following
conditions: heat, humidity and strength. IE, this screw will perform up to
X sheer strength and Y stretch...
It is very handy to use when approving things for other use. An engineer or
chemist can simply look up the MIL SPEC and say "That should do or Not good
enough!"
If something meets a MIL SPEC, you may look a the MIL SPEC and see if it is
mildew resistant for example.
I have seen guys say "this must be good stuff, It is MIL SPEC and then use
it" But remember, Gorilla glue meets *Mil Spec* MIL-A-46050C Type II Class
5. That does not mean that it is good for what you want to do. Or that a
mil spec is needed. There is a mil spec for duct tape, but some of the best
duct tapes have not been tested to any MIL SPEC.
Blue Standardized Skies,

Jack,
You are probably about right. As I read the Stewart info, it looks like a lot of
steps to get her done.
But I will keep plugging away.

Garrit,
The landing gear is built exactly to plans for the Sky Scout. My understandi
ng is that the Sky Scout was designed and built AFTER the Air Camper and in r
esponse to complaints of potential builders to the cost of the Model A engin
e. So Bernard designed the Scout as a single place plane with the Model T en
gine ( 25 Hp on a good day) that was very plentiful and almost free because t
he A had come out. The T's were filling up the junk yards! An A-65 should ma
ke it a hot rod!
The Scout has the same wing, tail and a little shorter fuselage. I guess the
gear was designed as an alternative for the "lighter" Scout. It is interest
ing that the plans for the gear just call for a spring that "is about 11" lo
ng and will hold about 400 lbs". Finding that spring is/was quite the chall
enge. Harley spring forks have springs the right diameter but too long and p
rogressive... do not work, too springy! Living in a farm community, I found a
GlenCo chisel spring plow spring that is close, but not yet stiff enough. B
ut I think it can be fixed with some fooling around. I'm becoming a "spring e
ngineer" (spring rate and spring load). Suggestions are welcome!
The gear placement is also according to plans and may not jive with William W
ynn's findings for gear placement (relation of wheel center to leading edge)
. I will find out.
It is also interesting that the plans call for the wing to be "sloped back 5
inches". I'm just using a modified J-3 tank as a header tank instead of a w
ing tank. That should help the CG, at least when it is full? I also added a
n inch to the mount. Guess I can always hang a 100 lb sack of beans between
the landing gear (lots of room there) if I'm still tail heavy. I figure two
hours in the Scout might be enough! When I fly it to Brodhead, over the Sie
rras and Rockies, I might need a wing tank, too!
How's that for an answer to a simple question?

Oscar,
The plans for the Scout call for 3/32" cable for all the cross bracing on th
e Scout and solid 14G wire for the tail, where I used 1/6" cable. I have the
AirCamper plans, but could not find the call-out for the wing cables to mak
e a comparison. As an engineer, do you think 3/32" is enough?
You certainly have a good eye. Did you notice the idler cable for the ailero
ns above the fabric on the wing? Kind of neat, maybe it will work as a VG th
ingy in some way! Hope it does not interfere with the lift, probably not muc
h to spare! I assume Bernard test flew it and obviously survived.
Thanks for the comments.

Navy surplus double breasted suits. Apparently, I was wrong.
Why don't you call your airplane by its' real name (DC-9) on steroids.Do they still

Ed,
DC-9 on some crappy steroids, if you ask me.
I have a DC-9 type because of flying the MD88, although I have never set foot in
the cockpit of any DC-9.
Makes sense to me.

| Subject: | Vi Kapler hinges |
Update on the latest batch of hinges. I finished up a representative pair
of hinges for load testing and rigged up the load testing jig=2C but ran ou
t of daylight before I could run the test. I want to make sure everything
is set up properly and can be photographed and documented before I run the
test. It's really not anything fancy or esoteric... a lever arm gives me t
he leverage to develop the required load on the hinges by using a 5 gallon
pail that I'm going to fill with wet sand and then weigh after breakage. T
he last set that Vi tested failed at about 700 lbs of static load=3B no fat
igue testing was done and we know that aluminum fatigues but to my knowledg
e there is no known or reported failure of these hinges and there are a lot
of them out there.
We expect the single-tab hinge half to be the part that fails since the mat
ing double-tab half has twice as much area to carry its load and the AN3 cl
evis pin is WAY stronger in shear than the cast aluminum hinge halves are i
n tension. In Vi's test the single-tab hinge half broke right across the h
inge pin axis. I suppose one other possible failure mode is "pull-out"=2C
where the pull of the hinge pin against the top of the tab causes it to bre
ak and the pin pulls through. My load test should go quickly.
I have now used all of the (simple) tools and jigging that Vi used to make
the parts in years past=2C and now that he's gone I look at each tool a lit
tle bit differently than I did before. His hands were the last ones to tou
ch the tools and jigs before I touched them today. I wish I could have got
ten the first set of hinges completed before he died so I could have told h
im about it=2C but I came pretty close.
The first set of hinges from this new run has been promised for a long time
to Bob Coolbaugh and Andrew King for the restoration of "Blitzkrieg"=2C wi
th nine other builders' names on the list after them. When they are availa
ble and ready to ship=2C I'll post that information here.
