Now that the Rudder is finished, it’s on to the next few tasks. I received the reinforcement plate for the Rami AV-525 Navigation Antenna to go onto the Vertical Stabilizer, so I had everything to get that fit in place.
First I did a bit of test placements and confirming the correct alignments with the plans. Then I marked the hole that needed to be enlarged and the part of the opening on the opposite that needs to be trimmed back.
Once that was figured out, I got out the step-drill bit and enlarged the hole for the Antenna to fit through. Then I trimmed back some of the other side for the second pole and deburred everything. Finally I put a grommet into the hole and some flexible edge protection for the other side and placed the antenna in for a test fit.
