Recently, I was sent an email asking me how about the static
ports I installed and how they were connected. After
reading a good bit on the Van's Air Force forum regarding
static ports I elected to purchase the flush mount static
ports from SafeAir1 and surface mount them. Note the
nipple in the first picture, it is designed to be flush with
the skin. The second and third pictures shows the static
lines running up around one bulkhead and through the second.
In this installation, #30 holes were drilled in the longerons
and then zip-tied in place. Notice how the static line
running to the instruments is well above the static port.
This prevents (I hope!) water from entering the static system.

Working down the list of little things to complete before
moving to the airport including finding a ground for the tail
position light. Although all the electrical equipment is
grounded on the firewall with the exception of the stores and
the wing position lights, I thought the tail light could be
grounded locally as well. Only one problem, my fuselage
is complete. What you see in this picture is the forward
side of the F720 bulkhead. I used some acetone to remove
the SEM primer to expose the aluminum so there will be a good
ground. The 16 AWG wire goes aft through the next two
bulkheads and into the rudder bottom. (3/8/07) |

Working just an hour I feel like I accomplished a lot today.
The first picture on the left is the top of the glair shield.
Loop Velcro cloth was glued to the top of the glair shield, a
grommet was installed to protect the GPS and XM radio antennas
that have to pas through it and edge banding was installed to
trim it out nicely. To cap it off, I installed the
"EXPERIMENTAL" sticker on the bottom side of the glair shield.
No missing that when getting in and with the canopy closed,
you won't see it. (3/15/07) |

Some times you just have to work with your spouse on some
things. The other night I took Nora out for dinner at
the mall that just happens to have a "Things Remembered" store
in it. So I brought along the Van's data plate and had
it engraved for $41. It took a day but when I got home I
drilled it to the aft left fuselage, under the HS.
Before pop-riveting it in place I etched, alodined, and
painted underneath it. (5/17/07) |

The top forward skin has now been riveted in place and I'm yet
to take a picture of it, maybe tomorrow. Tonight I
cleaned up the adhesive left over from doing fiberglass work
on the tail section and applied the temporary N-number.
The "list" is getting shorter every day. (5/27/07) |

Doug Bell makes these drop in replacement tail wheels for
around $200, money well spent, IMHO. The real advantage
to this type of tail wheel is that it presents the face of the
wheel to any pothole the tail might drop into. This will
allow the wheel to climb up out of the hole. Van's
standard tail wheel works more like a tail hook and has been
known to catch on things, like if you dropped the tail off the
edge of a concrete pad, and pull the aft two bulkheads out.
The other thing to notice is the Eye-bolts used to attach the
steering spring. A similar arrangement is put on the
bottom of the rudder horn. The advantage here is the
spring is almost horizontal and should be out of the way of
the rudder bottom. In addition, when the spring starts
wearing away at the attachment points, the Eye-bolts are easy to
replace. This
was not my idea, it was in one of the OLD RVaitors, which are
good reading.
(Parts List, four of each are required:
Eye
Bold Drilled AN42B-5, Cable Shackles AN115-21, Bolt AN3-6
(Drilled shank), Washer AN960-10, Castle nut AN310-3, Cotter
pins as needed)
The wheel bolt is long and bushed out on
purpose so a Cessna tow bar may be used on the tail wheel.
(The white bag is 20 lbs of OO buck shot. It is helping
hold the tail down with the engine mounted and no tail or
wings installed.) (5/27/07) |

Most RV builders don't enjoy working with fiberglass.
Yes, it can be a itchy and you MUST protect yourself from it
but I find the ease at which you can make unusual shapes just
amazing. The first step it align the gear leg fairings
so the plane flies straight. (The upper intersection
fairings on my plane are RV-7 parts from Van's and were good
enough to line up the gear leg fairings. They aren't
pretty and I will clean them up in the weeks to come.)
Everything was taped off so the fiberglass would not stick to
the leg fairings or wheel pants. Modeling clay to shape the
fairing. This picture was taken midway through the
forming process. (5/17/08) |

Once the clay is the shape you want it, lay some fiberglass
over it. In this case I put two layers of bi-directional
cloth on it. One helpful tip, draw on the wheel pant how
far you want the fiberglass to extend past the clay.

E After the FG hardened, a
metal putty knife was slid between the new FG and the packing
tape. This popped the fairing loose without any
problems. To remove the fairing I drew a line from the
wheel pant part line to the widest part of the gear leg
fairing on both the upper and lower part of the fairing.
A Dremal was then used to cut the split line on the lower
fairing which facilitated its removal. (5/17/08) |

With the fairing back at my shop it was easy enough to trim
and split the rest of the way. However, prior to
splitting them, a second layer of fiberglass was laid up and
this time peel-ply was used to help smooth the surface.

After the fairings were trimmed the wheel pants were installed
back on the plane. With the fairings positioned properly they
were drilled to the wheel pants and held in place with cleco's.
(Dipping the cleco's in Vaseline keeps the fiberglass from
sticking to them. A mix of flox and epoxy was used to
glue them to the wheel pants. Once that hardened, I
sanded down the edge of the intersection fairing and laid on
two more layers of fiberglass over the edge and wheel pants.
These strips were no wider than an inch and a half. This
may be overkill but I figure the wheel pants take one heck of
a beating, especially on grass fields. (5/17/08) |

F With all that work done, it
was time to sand the fiberglass and use micro-balloons and
epoxy to start filling the imperfections in the fairing.
