Thursday, October 29, 1903
Kitty Hawk, N.C.
Spratt went to K.D. Station with letters in morning. We worked all day on
front rudder, putting in uprights and making framework. Very little wind

| Subject: | Split Gear Tubing Size-Fuselage Height |
All,
The split gear plans (for the V's) call for 1-3/8" 14 gauge 1020, 14
gauge I think equates to .069 walls. Should I go with 1-1/2" .063 wall
or .080? Also for the flat plate used it calls for 14 gauge, .063 or
.080 for this?
Fuselage height- The plans call for 48-1/2" from the ground to the top
of the fuselage top cross piece with 19" tires. Mine are 25", do I need
to lower the gear or is the extra 6" height a plus?
Thanks!
Jack

Jack,
.080 in both cases. Did you try Dillsburg Aero for the 1 3/8"?
Aesthetics aside.....the positives of the higher gear is increased deck angle and
more clearance.....the negative is entry. You may need to position your fuse
in space and see if you can swing a leg over. I cant, so will put in a "horseshoe"
step ala Jenny. It's even worse for the passenger.
Make triple sure you stagger the gear strut attach tabs on the inboard axle ends
as wide as you can. The dims per print are too close and the gear hits where
it crosses unless you go cub style. I would go full forward on one and full back
on the other.

Jack,
With regard to the steel tubing, for 14ga, you would be looking for .083 wall thickness.
Metal gauges are confusing, to say the least. Looks like you're referencing
the wrong gauge chart, which is not hard to do. There are numerous different
gauge systems, and which one to use depends on what material you are dealing
with, as well as what part of the world you are in. I've attached a couple
of reference charts. One is specifically for steel tubing (which uses the Birmingham
Wire gauge), and the other chart references 5 different gauge systems,
with the related materials.
Now, with respect to the flat plate, I have no idea what gauge system is used for
4130 sheet. I haven't been able to track down a gauge chart that matches the
thicknesses that 4130 is offered in. The most commonly used gauge table for
sheet steel is the Manufacturers Standard Gauge, for which 14ga = .074. I'd go
with the .080" thickness on that one.
As for the fuselage height, Don Emch or Walt Evans hopefully should be able to
provide some "real world" info regarding split gear with skinny wheels.

Whoever posted about Titanium bursting into a white-hot inferno is just a t
ad off.
-
Titanium will not burst into flames at any temperature. It will melt at abo
ut 4400 F. degrees and that's way beyond what your torch is capable of. Mag
nesium on the other hand will combust and produce a white-hot flame even un
der water. That's why they use it in some military flares. If Titanium comb
usted at temps around 1000 degrees, the SR-71 would be a pile of cinders!!
Mag wheels on heavy aircraft are prone to overheating because of locked bra
kes and are considered extremely dangerous.
-
My wedding ring is Titanium so it will survive when I depart this existence
in a blinding flash of the purest white light. Moral: don't get a magnesiu
m wedding ring which could be the source of ignition for your departure.
-
Titanium must either be welded in an enclosed chamber or otherwise shielded
on both sides with an inert gas. Some Ti bicycle frames are welded in cabi
nets similar to a bead-blasting cabinet to achieve the atmosphere clear of
oxygen.
-
My exhaust is is just a straight shot-gun style and made from 4130 and I bl
asted it and shot it with VHT annually because of rust. Last year I took it
to our local powder coater and he did-some kind of-jet coating for me
and it seems to be holding up well so far.

Thanks for the report - great to hear the flights are going well. Be sure
to get some photos of the wooden struts and attach points - there's a few o
f us interested in that for sure (IE: me =3B )
Congrats again on the successful flights!

Great report Kevin, thanks for the good info (am covering a Corvair/Piet
now), (what made you think to suggest to avoid showering the wifes car with
metal grinding sparks?).
