Chapter 25 – Plodding to Finish

I started out today using the Fein saw to trim the overhanging glass that I laid up on the aft top (not glare shield) edge of the aft nose/avionics cover, at the seam with the front edge of the canopy skirt.  I then sanded the glass smooth to match the underlying vertical micro/foam.

I then flipped the aft nose/avionics cover over and did 2 layups: one on the left inside “flap” or “wing” that wraps around the nose over towards the fuselage side.  I discovered a delam here and cut out all the offending glass, and am laying up a single ply of BID to cover the bare wood underneath (Pic 1: And yes, we’re allowed to have would in/on these planes, but we have to cover it all in fiberglass to pretend it doesn’t exist… like a bastard sibling! haha).

I also needed to do another layup on the inside of the front left corner, and then added a very small dollop of flox at the edge to allow shaping this corner to fill in the gap better between it and the canard leading edge (pic 2).

I used Pro-Set epoxy for the layups above, and when done —not surprisingly— I had a decent little bit left in my cup.  I normally use fast hardener, so to be able to casually do an entire subsequent new layup from scratch is a nice break.  Here I’ve glassed the first (lower) of the two Clickbonds on the left side CS spar that will secure the left wing root forward heat shield… which will also serve to close the gap at the opening of the channel down the length of the wing and CS spar (hot engine compartment air = no good).

I had planned on starting my task below on the left side, but with my impromptu glassing-in of the lower Clickbond, I pressed forward on the right side.  I first made up a tape template, transferred that to foamboard and then pressed it into place over the numerous Clickbonds poking out.

Over the next day or few I plan on using this foamboard template to cut the underlying piece of Fiberfrax, and also as a template in CAD to plasma cut a thin piece of overlying aluminum (the firewall will be titanium).

Pressing forward!
