Installed Plenum Mounting Angle Nutplates and Carbon Fiber on Plenum

I installed the remaining nutplates on the plenum mounting angles.  After a little final edge deburring, this will be ready for priming and painting.

I picked up some carbon fiber at TAP Plastics and added an additional layer to the plenum.  Hopefully, this will stiffen it up enough.  Otherwise, I’ll end up adding some ribs on the bottom side.
