Doc and Jerry. Here is the prelim design.
The tubes from the lower end of the nose gear socket up to
the upper hard points are the breakthrough feature. This
supports the nose gear socket from rotating clockwise on
a hard drop in landing and still provides plenty of room
for a large oil pan  and a radiator and oil cooler mounted
under the engine. The tubes from the upper end of the nose
gear socket provide lateral support for the Schertz beam
and prevent the nose gear socket from rotating counter
clockwise (side view) in the event of a pot hole type load.
The engine has two degrees off set to the right and a 2.85:1
gear box must be used with this off set.
Only half the mount is shown.

Any comments.

I am glad you designed it for the 2.85 redrive as that is what I was
tentatively planning on. Tracy's.

I think the nose wheel is fully castoring, but I am not sure. Can anybody
say for sure? With a fully castoring nose wheel, is it possible to generate
a torque about the axis of the nose gear socket? I wouldn't think so, but
then I am just a poor ignorant software engineer (retired) . If such a
torque were to be generated how would it be dealt with? I understand the
tubes should be loaded only in tension or compression according to Tony
Bingelis.

The nose wheel retention bolt is a SOB to install; it requires a hole be
drilled in the firewall. I assume this is necessary to get the Lyc engine CG
where it needs to be for proper W&B. Since we have info that the CG with the
rotary was an inch behind where it was designed to be with the Lyc, and we
have agreement that the rotary should be moved forward that inch, does the
foregoing mean that the nose wheel tube also moves forward? If so, would
there will be sufficient clearance to be able to install the bolt and not
have to make a hole in the firewall? The fewer holes in the firewall the
better IMHO. Moving the nose wheel socket forward an inch means that the
nose wheel also moves forward an inch. Is that good, bad or indifferent?
Does moving the nose wheel tube forward cause an interference with some
engine part or accessory? Or do we leave well enough alone and keep the nose
wheel socket where Van put it and simply move the engine further away from
the firewall? Sigh. Why do apparently simple things have to be so
complicated?

No other considerations occur to me at this time.

All in all, I am delighted.

"poor ignorant software engineer" Some how I doubt that :)

If you drop the wheel down into a pot hole far enough anything is possible.
From reading the drawings there appears to a small bolt that keeps it aligned.
Strange that you should choose that failure mode rather than the
myriad of all other possible failure modes.

The nose gear can stay where it is.
From the side view dwg it appears that bolt has clearance.
Perhaps a capture nut is needed on the back side.
Are you talking about that little hole that says "tri gear only"?

Paul Lamar ...No rotor no motor.

The small hole that says "tri gear only" is probably it. I am not sure
since I have neither the nose gear nor any experience installing such.
I know it is a SOB from the info appearing on another RV list.
Incidentally some builders report using a taper pin instead of the
specified bolt because sometimes the bolt gets loose and causes other
problems such as shimmy and wear where there shouldn't be. On the face
of it, it seems like a good idea. But maybe Van used the bolt for its
shear value or other sacrificial purpose? What do you think? I would
ask Van's Aircraft "Builders Support" but am tired of the bumps on my
head from bumping into the stone wall.

A small complaint about MS IE browser. I can find no way to get it to
put my reply at the bottom instead of at the top, so I have to move it
every time. Does anyone know how to get it to put the reply at the
bottom? I prefer Linux but I have to use software that only runs on M$
windoze.

You should be able to forward it in Internet Exploder and
scroll down to the bottom of the message and start typing.

However Thunderbird is what my wife Robin uses on Windows and it
works fine. It is free for the download.

I use it on Linux. I do most of my email stuff on Linux
with Thunderbird and the Firefox browser and keep a Windows computer
around for the stuff that does not run on Linux. Namely Rhino.

Never had a virus in 7 years. The whole virus thing is a non
issue in Linux. The Windows users keep telling me for years a
virus can be written for Linux. In theory I am sure that is
true but I have yet to experience one.

There are two ways to move files back and fourth. One is a set
of tools called mtools. That simulates DOS commands such as format
and copy. I use that with a floppy drive for small files.

The other is if you burn a CD on Linux it is readably by Windows
and vice versa.

A third way is to set up a local area networked but
that implies access into your Windows computer by a hacker
that might get into your Linux system.


I have something like 60,000 or more
pictures and files and I could not do what I do with Windows.
I use 36 virtual screens. Each one is dedicated to a large
file folder or a program such as Thunderbird. There is
a small horizontal list on the bottom of the screen so you can
select the virtual screen, large folder, or program running in
the back ground, you are looking for instantaneously. I also run
XTree for Unix running in the back ground in each large folder so
there is a tree shown for each large folder. Xtree was the parent of
Windows Exploder but far far more capable. I also use the Gnome Gui
file system for rapidly finding the exact picture I want.
The Gnome gui file system has a ways to go before they catch on to
the way Xtree does it. The beauty of Linux is you can run
character based programs mixed with graphic programs using
the best user interface for the job.

Windows based "Find" is a cruel joke compared to character based
"locate" in Linux. If I had to use "Find" this newsletter would
not be pratical.

I digress big time.
