Misc Work on Various Parts

 In order to set the brake/rudder pedal position, the rudder was re-installed on the vertical stabilizer.  3/16" holes were drilled in the horn to allow the rudder cables to be attached using shackles.  The Rudder hard stops were adjusted with a grinder to allow +\-30 degrees of motion.  Attention was then moved to the rudder pedals.  A turnbuckle was attached to the two outside rudder pedals.  With the rudder pedals 6" from the firewall the correct rudder cable length was determined and the cable was cut to the length and a thimble was swagged.  The plans didn't call for rudder return springs, but we added two springs to the rudder pedals that attaches near the firewall for this function.

The elevator trim tab and trim servo were installed on the elevator.  The trim servo was connected to the imbedded wire we installed earlier in the elevator.

A cover for the trim servo was designed quite awhile ago.  The part was 3D printed but needed to be finished quite a bit.  The 3D part was sanded and then epoxy filler was added to the surface.  After a lot of sanding the part was primed.  After the primer dried, the part was painted to match the elevator with a coat of Vestal White paint.

We're still trying to find the perfect part for the brake lines that go from the Grove gear to the brake calipers.  We've settled on a 10" hose with 90 Degree fitting on one end and straight fitting on the other.  Parts have been ordered and we are waiting on delivery.

A lot of time has been spent on the FreeCAD designing the panel.  Still waffling on using either Klixon CB or Blade style fuses.  Each has its merits.  Currently leaning toward using the Klixon CBs.
