I believe Orndorffs finishing video shows it about as well as anything else.

Al,
Before you go and cut the flange off around the bottom, make sure you will
have sufficient edge distance to the rivets on the sides. I ended up
cutting the flange off with the cut-off wheel vertical instead of horizontal
and took advantage of the thickness of the flange so I had enough material.
Cutting with the wheel horizontal on Van's scribe line would have put me
dangerously close to the edge which would have resulted in a cracked canopy
and a lot of profanity.

hi folks,
i'm still doing my homework, and hope to start flying lessons
this summer, so that's how at the beginning of it all i am...
(but hey, i'll be attending the EAA workshop
on RV building this very weekend)
anyhow... i had decided to go with the RV8, and have been
reading about taildraggers... i came across the following...
http://www.airbum.com/articles/ArticleTailwheelTraining.html
the question is, IN FLIGHT, does the RV8 show
much "adverse yaw"?
thanks,

Adverse yaw has nothing to do with which end the little wheel is on, it's
primarily an aileron issue. Many older aircraft designs exhibit adverse yaw,
and most of the available factory taildraggers are examples of these older
designs. The Champ I learned in was a perfect example.
None of the Van's designs has much adverse yaw.

Al -
I have heard so much about the trepidations and timidity about dealing with
the canopy. I was so snakebit I put it off until I could not avoid it
anymore. My advice? It ain't that big of a deal. The canopy is like the
rest of Van's kit; just follow the instructions and do it step by step,
being careful and not using a lot of force. I think an important ingredient
is heat. Plexiglass likes heat. I had the workshop at 80degF when I did my
cutting. I used a diegrinder and it cut through the material like butter.
Same for drilling. Get the material warm and use the special plexiglas
drill bits. Sand down the edges with the final sanding at least a 400, and
preferably a 600 grit until the edges look transparent. Under these
conditions you'll find the plexiglas to be remarkably tough and capable of
withstanding a lot of stress. Important; be sure you use the weak aluminum
rivets when attaching to the canopy frame, and not the CS4-4 or equivilant.
You will be sure to crack the canopy if you use the CS4s. Just follow the
instructions, use your instincts, sense when you are about to apply what
feels like too much force, and step back for a moment to reassure yourself
that you're on the right track. You too will wind up with a good-looking,
flawless canopy wondering how you did such a good job, just like I did.
Keep on truckin'

Andrew -
An intresting thing, adverse yaw. I think of it as the tendancy for the
nose of the aircraft to yaw opposite the direction of turn when rolling with
aileron only; i.e., when rolling left, the nose swings to the right. It was
so pronounced in the F-100, in high-g turns you left the ailerons neutral
and rolled strictly with the rudder.
My RV-8 exhibits very little adverse yaw. If you leave your feet on the
floor, and apply a lot of aileron, of course you're going to see the ball
slide to the inside of the turn, just as you would in a J-3 Cub. Stomp on
the ball to get coordinated again.
Regards
Don

Adverse yaw? I go back and forth between my RV-8 and a glider and they
couldn't be more different. I've never flown an aircraft with less adverse
yaw than an RV, and of course gliders with their ailerons near the end of a
60' wingspan have LOTS of adverse yaw. Once above pattern speed you really
use very little rudder in an RV (some will say none, but if you *really*
want to keep the ball centered you are applying tiny bits of pressure when
maneuvering). In the glider you put in a healthy does of rudder when banking
the aircraft almost before the aileron. Cessnas, Citabrias, etc. are
somewhere in the middle. My understanding is that adverse yaw is largely a
function of wingspan and the leverage the extra drag of the outboard
(rising, therefore increased drag) aileron has relative to the fuselage.

Thanks Larry and Paul,
I guess I did not explain my self well, I too only have about a 1/4 inch of play
when I put the roll bar on the fuselage. The 24" was just a convenient place
to measure on the roll bar and the 32" was to the outside of the fuselage.That
said it would appear that the roll bar is the piece I need to work on.
Larry I am curious how you used the engine hoist to spread your roll bar , I have
tried the approved Van's method but neither my back nor my muscles were up
to the job!
