Since I
need help every time I need to move the canopy from the plane to the bench
for cutting, I started a new project while waiting for some
assistance. I decided to assemble the main gear wheels and brakes. The
pictures on the plans are not nearly detailed enough regarding this area,
so these pictures should help you get through it. (someone please
let me know if I've done this incorrectly) This is the
right gear leg, looking down on it from behind showing the brake flange
bolted in place with the brake mount fitted. |
|
|
The aluminum piece that the wheel pants attach to is
held on by three bolts and spacers to keep it away from the brake disc. |
 |
|
The brake bleed valve (black) must be moved to the
bottom for one brake (they both arrive the same way). The pad is
unbolted from the brake. The brake is then slid into the two holes
and it "floats." |
 |
| |
 |
|
This is what it looks like with the wheel in place
and the brake caliper bolted in place around the disc. The nut
holding the wheel on could fall off and the wheel would be still held in
place by the brake caliper! |
 |
|
Now that both main gear legs and wheels are safely
back in the attic, it is time for the inevitable task, cutting the canopy
in two.
This is the canopy in place over the center roll
bar. I've put marks at the cut line right over the plastic.
Next, I used a knife to cut right through the top layer of plastic to
lightly score the plexi. |
 |
|
I then peeled the protective plastic back about an
inch, trimmed it, and put down masking tape strips leaving just enough
plexi showing at the cut line for the trim wheel to guide between.
Strips of duct tape are used to hold the piece in shape during cutting.
|
 |
|
The garage is about 70 degrees. Good enough... time
to make the cut! |
 |
|
This is the first pass, just a quick run with the
cutter to get about half way through. |
 |
|
And less than 5 minutes later, it is done.
Thinking about it was much worse than just doing it.
By the way, if you've managed to get the canopy close
to the roll bar at the top, it will fall into place nicely after the cut
is made. |
 |
|
Now it is time to deal with the ears that overlap the
canopy at the front corners. I cut the aluminum into more of a V
shape rather than a skinny U to make more room for the plexi to go
through. |
 |
|
Here's a tip I wish someone else would have told me
about sooner... so I'll tell you.
Get a box that is just the right size, put it on a
narrow table, throw a couple of towels on it for padding, and you'll have
a great way to position the canopy for all the trimming and polishing
you'll be doing for the next 6 hours or so. It will hold the rear
window nicely while you work on it too. |
 |
|
I drilled the holes in the canopy frame side, and
marked the top of the joggle to make it easier to see. After
trimming the canopy to the line, I drilled through the canopy to the holes
using a plexi bit. I also drilled the canopy to the rest of the
frame the same way. |
 |
|
Here a shot of the canopy completely drilled and
clecoed to the frame. |
 |
|
I then started work on the rear window. After
fitting and drilling, it needed a bit of trimming at the roll bar. I
put down a strip of tape with the edge where I wanted the cut line, and
then trimmed to the line. This is the picture after it was put back
in place. |
 |
|
Now I needed to trim the rear edge of the front
canopy because it overlapped the rear window. I put a piece of
masking tape down on the roll bar, and put the rear window in place.
I then drew a black line on the tape along the window edge. |
 |
|
I then removed the rear window, and put the front
window back in place. Now, I can put down a strip of tape on the
front window, with the edge right over the black line, and trim it to
size. |
 |
|
Here are a few photos of the side canopy details as I
worked on fitting them correctly. |
 |
| |
 |
| |
 |
|
I finally riveted the top canopy frame skin, and the
sides came around nicely to match the fuselage sides. I filled the
pop rivets along the top with epoxy and filler. |
 |
|
The canopy brace is an optional part that should just
come with the kit. This shows the brace installed after I painted
the first coat under it. |
 |
|
I put spacer blocks between the upper canopy skin and
the frame where they didn't fit quite right. Then I filled the space
with epoxy and filler. This photo shows an intermediate step.
After filling it, I used a scotchbrite roloc pad in a die grinder to
smooth it off nice and flat. |
 |
|
I reworked the rollbar, sanding most of the paint
off, and filling all the space around the rivets and the centers of the
pop-rivets. I think it looks a lot nicer this way. |
 |
|
I installed the manual aileron trim one evening since
I was getting tired of seeing it on the shelf. The wires to the
springs are temporary. |
 |
|
If you didn't notice from the previous photos, I've
been cutting more and more holes in the instrument panel, including the
hole in the subpanel for the radios.
Screws will go through the radio trays into the large
angles in the front panel. The angles extend all the way up to
accommodate future radio expansion and the hole in the subpanel is big
enough for expansion as well. I'll just need to enlarge the front
panel hole for more radios in the future. |
