The weather didn't look much better than yesterday as I looked out the window down the driveway.  Once again, a good excuse to stay inside in the relative warmth and work on the airplane.


I continued work on the second static system.  A short length of 1/8th plastic tubing slips over the drilled screw and is sealed with RTV.  I routed the tubing for the 2 static systems (that I labeled L & R) up along the bulkhead.


I brought the tubing down each side because it was more convenient than bringing them both down one side.  They enter a piece of flexible conduit at the bottom of the fuselage and route forward on the left side of the cabin.


At the spar, the tubing passes through an opening with the appropriate grommet to the outboard left side of the fuselage.

The tubes turn 90 degrees to pass through the spar.


Forward of the spar, the tubes are routed through the left gear leg mount and along the cabin floor.


Finally, I brought the tubes up along the fuel vent lines where the remaining tubing was coiled until I get to the panel work.  Is this the final routing?  I don't know.  I will look at it again when it is time to finalize the hookup.















I want to get the gear ready to install, but I don't want to have to bend down and work on the tires, wheels and brakes on the floor.  I want to do it on the bench.  I started by making the spacers that keep the wheel pant mounts away from the brake rotors.  They are simple pieces of T6 tubing cut to a consistent length.

The spacers go the bolts that pass through the brake flange.

ne of the bolts does not get a spacer (it's shorter than the other 3) because it doesn't attach the wheel pant bracket.

All put together and waiting for the wheel and brake assembly.  I'm proud of myself.  But Wait!  It doesn't look right!  Sure enough it isn't.  I assembled it backwards!

Everything turned around and reassembled.  That looks better.

Backing up to a small point.  The through-axle bolt that holds the brake flange in place takes 2 washers.  The first fits up onto the grip or shoulder of the bolt.  It must be ground to clear.

A second and smaller washer fits up against the first.  Because it is smaller in diameter, it does not need to be ground.

The two washer and the flange bolted in place.
