Chapter 13/18 – Nibble, nibble, nibble

Here’s a shot of my starting point today with all the avionics bay foam reinforcement pieces in place.

Clearly I was missing the right side glare shield 1/4″ foam substructure.  When I claimed yesterday that I had no backside clearance for nails, it dawned on me this morning to not let the nail holes go to waist and use toothpick tips as wooden spikes in the same manner as we did when we build the canard!

I then floxed/micro’d the right side glare shield 1/4″ foam substructure in place.  I have to say my wood “spikes” worked a treat!

So, here’s a shot of all the aft nose foam in place.  From here on out any foam that is added will be a permanent part of the external nose structure (as versus the cover).

Here are a another few shots of the avionics bay reinforcement foam structure and the foam glare shield substructure.

I took a wider angle shot to show how the progression of the nose is coming along.

I then spent nearly an hour cutting glass. I then prepregged and wet out 2-ply BID tapes for the underside layups of the avionics bay reinforcement foam structure.

Here you can see the over (or under!) hanging glass of the avionics bay reinforcement foam structure layups.  I was on the fence about peel plying the layups, but it is so hot and humid that the glass seriously wasn’t overly interested in sticking to the wet micro’d foam! Using peel ply was magic and kept the glass wrangled and right in place!

Here’s a smattering of pics showing the BID layups on the underside avionics bay reinforcement foam structure.

After the underside avionics bay foam reinforcement structure was glassed and peel plied, I then set my sights on the 2-ply BID layup for the underside of the foam glare shield sub structure.  Again, I most definitely peel plied it as well!

Here’s another lower angle shot of the 2-ply BID layup on the underside of the foam glare shield sub structure.

My last official act of the evening was to razor trim the avionics bay reinforcement foam underside layup glass edges.

Tomorrow, my goal is to get the top side of the avionics bay foam reinforcement structure and the glare shield sub structure glassed.  After that, I can move on with the “standard” (LOL… right!) nose and canopy build.
