Brief Description: Fwd Fuselage - Drill Firewall Side Skins
When I came back I again ensure the firewall was 5/8 from the skin fwd edge. I ensured brackets were all clamped. So I drilled the first two holes on bottom skin. Just two per plan. Then I drilled the side skins to firewall. I tried a steel bit but it did not work as well as my regular Avery #40 bit. I started at the longeron and moved down which was really up since it is upside down.
