I wanted to assemble the Ray Allen POS-12 Flap Position Sensor. I cut a small section of piano hinge and riveted the Position Sensor to one wing of the hinge. The parts I used were a bent piece of aluminum, a 1" Cushion Clamp, AN526C632R8 pan head screw, and a MS21042-06 tiny lock nut. To allow a slight offset between the bent aluminum and the sensor arm, I 3D printed a small bushing. I still need to find the correct position to rivet the upper portion of the hinge to the rear spar bulkhead, but I think I am close. I'll need to connect a Molex connector or perhaps a small terminal block to the 3 wires on the sensor.
