Firewall riveting mostly complete

I modified my #30 dimple die using the grinder, to dimple the bottom-most holes in the firewall bulkhead:

Modified dimple die for dimpling the bottom holes of the firewall bulkhead

then continued riveting:

Fully-riveted firewall forward side

Fully-riveted firewall aft side

With this, the only parts missing on the firewall are sealant (which I plan to apply later) and the rudder pedal brace (which I didn't want to install until I figure out how it'll work with the ControlApproach pedals).

Time lapse:

Total firewall rivets: 596
Total firewall time: 58.4h
