|Inspection panel backing plate/cover, fuel valve flanges and scat tube support with nutplates riveted|
|Forward fuselage ribs with nutplates, inspection panel backing plate, nose gear tension fittings and fuel valve bracket flanges riveted on|
|Forward fuselage rib riveted to nose gear tension fitting|
I then dimpled the recess box and the firewall bulkhead to accept the rivets:
|Dimpled firewall bulkhead|
|Firewall bulkhead with most parts riveted to it|
|Forward side of the firewall bulkhead, with most parts riveted to it|
In the process, I also realized that the rivet gauges I have don't match Van's spec - Van's allows smaller shop heads overall, and with some of the rivet lengths they specified, it's impossible to get to the gauge's "official" spec. This applies to most firewall bulkhead rivets, so I had to measure those with a caliper - specifically, the gauge has a hole that's about .19", and the spec calls for .163". The height was almost right on the gauge - the gauge has .06", and the spec is .05".
|"Standard" rivet gauges don't really match the MIL-spec that Van's recommends|
There's still quite a bit of riveting left to do, but this is a good start.
Total firewall rivets: 512
Total firewall time: 49.9h
