Plenum trimming, inlet layup, baffle work
Trimming of the plenum continued with the use of a new cheap sander. I think this is the first of many “duplicate” tools that will be going to the hangar. Once I had enough of sanding for now, I decided to go ahead an do the glass layup to reconstruct the outboard ears on the inlets that I had to chop off. Once that had setup enough (next day), I popped the plenum back off and began the task of drilling for about 35-40 nutplates around the top flange. Whoever said that building an RV was perfectly enjoyable without a #8 nutplate jig must have been crazy. I wouldn’t want to build without one.
Finally, I took all of the baffles off for final adjustments and installation of the plenum nutplates. Before they went back on, I filled most of the part fit gaps with high temp RTV. I used the small head NAS?? rivets for all of the nutplates. Just a little tiny machine countersink on each hole with a deburring bit and you’re ready to squeeze.
