Drilled more firewall parts

January 23, 2014 – I slipped out into the garage today to do some more drilling on the firewall parts.

I drilled the other F-601J angle. In my post yesterday I didn’t show the specifics about drilling this angle. According to the plans, it’s supposed to be 3/32″ off the bottom of the angle at the bottom of the firewall. I slipped a #40 drill bit in as a spacer and clamped the angle and spacers in place.

I fit the spacers for the upper engine mount brackets and clecoed them in place. I had to drill two small additional fillers.

I drilled and clecoed the F-601E stiffener in place. Here’s the firewall as it sits right now:

I still have to make and drill a couple of doublers for the firewall.
