Chapter 25 – Last major micro-finish!

Yes, I’m continuing to highlight just how friggin’ hot it is inside the shop… yet another 100° shop day.

I started off by pulling the peel ply from the right winglet intersection fairing.  All looked good and after some minor cleanup and sanding, it was ready for micro.

Which I got to next… here is the last major segment of the plane that required micro, yet another major milestone (#3 major milestone coming up with the last major epoxy wipe!).

I then did a good bit of sanding and then wet sanding on various epoxy wiped areas: aft wheel pants and turtle-deck, as well as some errant epoxy on the topside of the left wing TE and winglet fairing.

I also knocked out some non-planned tasks inside the inverted right wing root, adding some more heat shield on what is actually the top inside surface of the wing root, and adding a ply of BID to each forward face of the 90° heat shield mounting tabs, as well as some micro fill and a ply of BID over the modified angled corner where the front inside wing edge meets the CS spar flange (both for cosmetic and reinforcement reasons).

I also cut out the edges of the foam on both top and bottom segments of the aft face of the left winglet intersection fairing.  I essentially made “flox” corners for laying up a single ply of BID, but for weight reasons I used micro vs flox since this is not a critical structural component.

After laying up the BID, I then peel plied the layup.

With that, I called it a night and left the layups and micro’d bottom right outboard wing and winglet areas to cure overnight.
