Wings



2 hrs

Riveted Landing Light bracket to top & bottom skin of LH Wing.  

Assembled Left Fuel Level Sensor.  Bent wire for float following full size drawing on 18-10.   Per Van's builder support advice, I measure output resistance at both ends of travel at 32 and 249 ohms.

 Next I did my first of several trial fits - and used my new borescope to check inside tank.  I measured 32 ohms in initial position (wing is upside down...so "full" position).  I'll need to flip wing over to examine at opposite end of travel ("empty" reading and clearances).   As shown in pictures,  I adjusted alignment (twisted wire) so float better aligns with bottom of tank.  This hasn't changed 32 ohm reading on multimeter, and can't confirm if I have 1/16" clearance to bottom of tank.   I'll need to flip wing over to determine if full travel (249 ohms), and how well or poorly aligns with bottom skin.

Prior to adjust float angle vs top of tank  (via borescope).

After some adjustment...closer to parallel.  Need final tweak to gain 1/16" gap per instructions...although Van's builder support told me not required.
