Last night and tonight I worked on the air vents, installing them in the cockpit tonight.
The vents (SV-6) arrived from Vans on Friday, so I got to work positioning, match drilling, and trimming the parts per the plans.
I installed some aluminum honeycomb in the vent to stop any large insects or other critters from getting access through the vent shaft. This worked out ok, and I feel slightly better knowing there is something to act as a barrier.
