Just finished redoing the leading edge of the one elevator
shell...again!. Looks pretty good this time. Now I need to figure out
how to set up a small router to cut out the hinge access points so
they look good.


I would use a jig, and a router bit to follow the jig. Make a big letter
"O", of whatever size and shape you need, tape it to the surface, and let
the non cutting surface of the bit follow around the inside of the template,
using rotation to force it to the template. I hope this is clear enough.


That's pretty much what I've been thinking, but the leading edge
curves down and I having come up with a form to follow the edge.
My big router, which is way too big for this job has some bits that
have ball bearings on the shanks for roll along the guide.
I'd like to come up with something like that on a 1/4" bit and I have
some aluminum channel that I could probably form to fit the shape of
the elevator skin. I'd use 1" angle for the back of the cut and run
the angle full length of the skin which would make the cuts uniform.
OTOH it takes a steady hand even with a guide. :-)) It that bit,
bites it can make it through the guides and half way across the shell
in an instant. Then I'd be rebuilding more than the leading edge.
No, I wouldn't. that'd be the point where I called New Glasair and
ordered a new set of elevator skins.

Roger:

Just lay out the "U" shape with a fine point marker, the go to work with a
1/2" diameter sanding drum in a Dremil tool. Rough-out the opening, sand
into each corner, free-hand to within 1/16 of the three straignt lines, then
finish sanding by hand with a small sanding stick.

The whole procedure can be completed in less time than it took me to
describe it.

Actually they are rectangular notches about 1" deep and 3" wide.

But.. that takes skill.

Actually I did the narrow ones very much like this. Rather than the
sanding drum I used a cut off wheel. You let it run along the surface
line (slightly undersize). It will create a grove which makes the
following passes stay true until you eventually cut through.

Narrow ones?

Backing up a bit here. When the horizontal stab is upright, the
elevators have slots on top about 3/8" wide cut to clear the hinge
arms. The under side of the elevators have the hinge bolt access slots
so you can remove the hinge bolts and then the elevators.
The elevator travel is limited to about 30 degrees nose up and 18
degrees nose down. When at rest it is also at the nose down limit and
the narrow (top) slots are barely visible. OTOH the access slots are
always visible from the underside even when the elevator is full nose
down.
With the elevator full nose up the hinge bolts are fully exposed.

My goal is to get the access slots straight, square, true, with
radiused corners so they will look like who ever did them knew what he
was doing.

Certainly! :-))

If I have to resort to jigs, machine tools, and plain old technology
to replace skill, I'll do so in a second...IF it's within my financial
means to do so.

Every one, or at least those who follow the directions just close the
elevators, horizontal stab, ailerons, and flaps on a flat table and
use weights. I weld up fixtures to hold things straight and then
clamp them together. Of course if I get too enthusiastic with the
clamps I could end up with very thin elevators.

Clamps are at the bottom row on the page.

except something seems to have gone wrong with the page and I can see
the photos for the bottom third. Looks like I'm going to have to call
the ISP as I've not changed anything. I probably just need to reload
some *stuff*.

Oh, to heck with it. I think I'll go to the airport and play.

How about that! "The Problem" turned out to be NORTON's INTERNET WORM
CHECKER giving a false positive on an image, P4269091T.jpg which is
the image above the "Triangular rib setting in place" Caption. It not
only was creating a warning and blocking the image it was preventing
the page from loading any farther.

sheesh Just when I was laughing about their competition's screwed
up, up-date last week.

Ah, well, I have at least three other operating worm and termite
checkers and I can still leave the real time virus checking turned on.

So, just as a warning to NAV 2006 users, it does give false positives,
or at least in one instance

That's not all Norton screws up!
I won't even consider using Norton any more, - ever since Symantec
took it over from Peter Norton, it's become a stinker - and it gets
riper every year. Support is non -existant. I remember when , back in
the early days of Norton Utilities, Norton DiskDoctor, etc, when you
had a problem you called tech support, and you talked directly to
Peter if his support guy didn't have the answer right at his
fingertips. Talked to Peter quite a few times in the early years.He
never failed to answer the question and solve the problem - at NO
CHARGE.
Now you pay the droids, and they STILL can't answer the questions and
make the product work.
