| Subject: | Canopy Construction - Gluing it in place? |
--> RV9-List message posted by: "Dave Nicholson" <n347sd@insightbb.com>
After reading the "Nuts & Bolts - Craft & Technique: Fitting Plexiglas Canopies"
in the January 2004 issue of EAA Sport Aviation, I contacted the Sika Corporation
for their recommendations.
Here is what they said:
Dave,
I read the article about the RV canopy installation with Sikaflex. Let me
start by noting that we have no experience with aircraft applications and
any of the challenges found in such an application. That being said, the
following link is a set of installation instructions for using Sikaflex
295UV for marine windows. The steps would be the same for your
application.

To purchase this product, contact Merritt Supply at 954-946-5350.
Regards,
Steve Padgett
Sika Corp.
Rather than use Blind Rivets to hold the Plexiglas to the Canopy Frame & Roll Bar,
I decided to drill & tap all of these holes for #6 SS Flathead Bolts, so I
intend to use the Sikaflex-295 UV in conjunction with the screws already installed.
After the Sikafles-295 UV has cured, I will "back-off" the screws slightly to relieve
any pressure they were applying to the Plexiglas.
I will also use the same material as a "sealer" between all of the Canopy Skirts
(side & aft) and the Plexiglas Canopy to prevent rain water from running into
the cockpit.

Anybody else have trouble getting the j-stringer fastener line to
line up with the holes in the skin? The line, drawn 3/8" from the aft
end as instructed, ends up pretty far forward on the stringer, near
the bend, and the ribs don't allow me to push the stringer aft enough
to line up with the holes. It's not off by that much when the stringer
is pushed firmly against the aft edge of the rib gap, but I can't imagine
that's how it's meant to fit.
I ought to just draw a line on the center of the face of the stringer
and be done with it...

Folks,
Trying to figure out which side of the HS-903 rear spar the
shop head of the AN470AD4 rivets should be. If my reading of
the drawings is right, the shop head should be on the forward
side, but I've been scouring around the various blogs and some
people take the opposite tack and some people mix it up.
Any big deciding factor here ?
Regards,
g

So what's the secret? My hands are black and blue from trying to
press those guys into the skin. I've been good about fluting and
flanging... I got one in with a lot of struggle but the rest require
at least 100 pounds of pressure to get the bottom flange anywhere
close after clecoing the top flange. I've put some boelube on the
flanges too.
Can't imagine how the tanks are going to be...

I believe as a general rule, the machined head goes on the side with thinner
aluminum, but sometimes circumstances make that difficult. So, shop head
,as general rule, goes on thicker material.

Two possible deciding factors that I have found:
1. Put the shop head on the side that is not normally visible if you
have a choice (if you are going for looks).
2. Put the shop head on the side with the thickest material so it
doesn't tend to deform the metal as you form the head (if you are going
for function).
3. Put it where it works (sometimes you really don't have a choice).
My $0.02.
