Dimpled and countersunk firewall parts

Dimpled the firewall sides.

Machine countersunk the firewall angles to mach the dimples in the firewall. Unfortunately I got distracted and neglected to tape off the holes I wasn’t supposed to countersink in the diagonal firewall angles. So two new additions to the scrap pile. New parts ordered. Moving on to the next section in the meantime…

Before moving on to the next section, I was able to dimple the firewall top section and countersink the associated angle as well the relay doubler.
