In the winter of
'92, the workshop was moved to a corner of a hanger at the Mojave airport.
Some of these pictures look somewhat dark because they were taken at night
after work. Ready to start cutting the fuselage parts. This was a 14 foot
table with a blue-chalk line snapped down the middle. |
 |
Here's the first
fuselage side frame going together. |
 |
Phil Miller
works the front fuselage side plywood. |
 |
I used these
cross members to clamp the fuselage gussets in place. There are virtually
no nails in the fuselage. |
 |
More detail on
the gusset clamps. |
 |
The idea was to
create a vacuum bag for the gluing of the front fuselage
plywood. I didn't want nails working themselves out at a later date,
so in all possible cased, I have avoided brass nails. |
 |
Here we have
just about sucked all the air out of the bag and have achieved a good
seal. By sandwiching the two ply sides in the middle, even pressure is
applied resulting in a nice even glue line. |
 |
It was getting
to be winter in Mojave and it gets somewhat cold there. I made up a tent
that worked great for keeping the glue warm during curing. |
 |
Once the sides
were complete, I had to figure out how to build the fuselage while level.
This arrangement worked out fine and allowed a very straight
fuselage. |
 |
Here's the
fuselage loaded in the fixture and level. |
 |
To lock in the
squareness of the fuselage, the seatback bulkhead goes in first. This is
really the only place nails were used as there really wasn't a way to
apple clamping pressure to the seatback ply. |
 |
This are the
laminates under the instrument panel deck. Forms were made, then
wood soaked, dried, then laminated. |
 |
The instrument
deck goes in. |
 |
In this picture,
I'm aligning the fore and aft lower wing attach fittings. As far as I can
tell, this worked. |
 |
Some of the wood
framing goes into the bottom of the fuselage prior to fitting the floor.
Here's the forward seat bottom frame and associated cross members. |
 |
First serious
metal work. These fittings are the stick assembly prior to welding. |
 |
Here's the stick
fitted to the fuselage. With a stick, and the seat, seen placed in the
fuselage, airplane noises cna officially be made. |
 |
This is the rear
fuselage with cross members being installed. It was important to keep the
fuselage centered over the centerline while pulling the fuselage sides
together. |
 |
The vertical
fixture at the tail helps ensure that the tail has been drawn together
correctly and is square to the forward part of the fuselage. |
 |
Here's another
shot of the tail after gluing the tail together. Also note that the
digital level is right on 0.0, ensuring that the fuselage is going
together square. |
 |
Couldn't resist
putting the tail on after the installation of the tailpost. |
 |
Here's the final
installation of the multiple gussets in the tail. As I mentioned before,
you can never have too many clamps of various sizes and shapes. |
 |
After the tail
is pulled together, the turtle deck goes on. Here I'm figuring out where
the stringers are going to go. |
 |
Note the
difference in the stringer formers aft of the seatback bulkhead. I didn't
like the way the plans said to make those formers so I improvised with .25
birch ply. Ended up working well. |
 |
Here's the
turtledeck stringers going in. These were .25 square spruce strips
laminated in place. The curvature is a difficult to work with here. |
 |
Rear shot of the
stringer lamination. |
 |
Newly installed
turtle deck stringers. The gusset for the vertical stab forward mount is
clamped here. |
 |
Also, I'm
clamping the horizontal stab attach pads. |
 |
The ply fairing
for the forward turtle deck is going on. |
 |
Rear view for
the same operation. |
 |
Completed
fairing for the forward turtle deck. The only thing I regret is not
beefing up this area a little more. While getting in and out of the
airplane, you tend use this area to sit before sliding into the cockpit. |
 |
Rudder pedal
fixture for welding. Very simple. |
 |
Cloths line
works great to determine the cable runs for the elevator and rudder
controls. |
 |
I finally get to
try this on for size. |
 |
This is the
second of three formers for the seatback, instrument panel, and
firewall. |
 |
I made the
interior cockpit trim strips out of a block of black walnut and poplar
sandwiched. Then used a band saw to slice thin strips which were glued to
the interior longerons and instrument panel cross member. |
 |
Here's the
cockpit with the trim installed and the combing temporary installed. I was
also trying out different instrument arrangements. The stick is also a
black walnut/ poplar laminate but I decided to go with an all steel stick
per plans. |
 |
I used the two
2x4s here, clamped to the firewall bracing to make legs for the fuselage.
Worked great for supporting the fuselage during work on the belly. Here
you can see the forward landing gear fittings and tension strap. |
 |
A heat tent was
necessary as the fuselage coating was done during the winter of '93 at
Mojave Airport. It does get cold there! There's only a couple of
pictures of this process because they all look alike. The process entailed
a lot of sanding to about 400 grit, coating with Chem-Tech L-26 Sheathing
Epoxy (now owned by Three Systems), then sanding, and more epoxy. The L-26
is very close to the West System laminating resin, but is designed as a
top coat. I put on three coats of L-26, with sanding in between coats,
then coated applicable areas with a coat of spar varnish. Don't coat
anything that has a fabric attachment with spar varnish unless it's epoxy! |
 |
More fuselage
coating. I used an engine stand for the front fuselage to allow easy
rotation of the fuselage. |
 |
The interior
received a couple coats of spar varnish, sanded in between, to achieve the
finish I wanted. I was overall pleased with the process, although the
entire fuselage coating took about three months and countless hours. The
spar varnish can be rubbed out after it cures. |
 |
Here's the
cockpit floor after coating. Nice shine, eh? |
 |
Fuselage
fittings ready for installation. I thought there were a lot here. Little
did I know that the wings had in store! All steel parts were powder-coated
by Pyramid Porder Coating in Burbank, CA. This was reasonably priced and
the coating is pretty much indestructable. |
 |
Sitting outside
the garage/ workshop in Chino Hills, CA sometime in the summer of '93. I
started work for Northrop and moved the whole thing to the LA basin.
Notice that the main gear has been temp installed and the tailwheel
has yot to be installed. |
 |
Another view at
the same time. |
 |
Rear view in the
summer of '93. |
 |
Spring of '94 in
Rolling Hills, CA . After six months in Chino Hills, I moved in with some
friends in the more climate-friendly area of town overlooking Catalina
Island. Yea, it was a rough life. At the time, I was working second shift,
so I had most of the day to work the BF. |
 |
The harness is
in. The harness was made by Hooker and turned out very nice I
thought. |
 |
Instrument panel
almost ready for installation. The only thing missing is the mag compass. |
 |
Step one for the
cabane fixture. The box-like base is the same size as the interior of the
upper forward fuselage. |
 |
The 4130 tubes
start the fitting process. |
 |
The welded
cabane strut during fitting to fuselage. |
 |
The tank
is set in place for fitting. It will eventually get painted white. The
fuel level indicator is a spiral float-type that was originally to be used
in a guy's Glassair header tank. It is an easy installation and seems to
work well. Also note the angles screwed to the top longeron. I didn't like
the wood blocks per plans so I used this with nut plates. |
 |
Another
tank view with cabane strut fitted. Forward of the indicator is the
scupper and fill neck. I ran a 1/4 AL tube over the side of the tank and
then through the fuselage bottom to provide a drain to spilled fuel. This
feature really does work! |
