Brief Description: Fuselage - Firewall - Drill Dia 1/4" holes in F801
With the Firewall replacement parts F801H-1 L/H and RH and F801L received a while ago, I decided to finalize the pre-fit of all parts on the Firewall Sub-Assy. In order not to repeat the mistake I did when I first drill the Dia 1/4" holes in F801L and F801H parts (and ensure proper E/D in F801H parts), I first made a setup to properly support the Firewall while drilling with the Press Drill. I then drill the two holes, one at a time, and taking all the time needed to ensure perfection this time.
I worked on this from 17h00 until 18h45
Firewall properly supported and clamped on press drill
Hole in F801L lined up with the laser on the press drill
