While waiting for some paint to dry, I decided to tackle the fuel flow transducer mount in the forward fuselage. First, I cut some heavy-duty aluminum angle. Next, I drilled out the four holes in the angle to their final size (#30 for the outboard attach rivets, and #27 for the two holes where the unit will attach using #6 screws.)
Since the attach holes in the unit are set up for AN-3 bolts, I made some screw bushings out of aluminum spacers. These will slip into the large holes and make them perfect for the smaller hardware I'll be using.
I drilled the attach angle onto the fuselage longeron just outboard of the fuel pump. This location will keep it on the "cool" side of the firewall, and also satisfy its requirement to be in an undisturbed section of the fuel line.
Transducer mount clamped in place. Pilot holes will act as drill guides for the longeron.
