Chapter 25 – Left wing micro-finished

Last night I knocked off about an hour earlier than I normally do to fill out the paperwork to get a new passport, since I need to travel to California for a reunion next month and also plan to travel out of country both with the new Long-EZ and overseas for some adventures with Jess.

My passport appointment was late morning, so before I left I wanted to get a task or two done as I let last night’s layup cure a bit more before I pulled the peel ply.

I turned my focus to the aft upper lip of the left strake where I had laid up 2 plies of BID on the underside of the lip.  The lip trailing edge had a fair amount of dings on it, so after I trimmed the cured overhanging BID a bit I then added some flocro to these aforementioned dings, etc. (pic 1).

Trimming the remaining glass and sanding it all nice and straight was a perfect task for this morning, so I knocked that out and was quite pleased with the results (pic 2).

After returning home from my passport appointment and running a few errands, I then pulled the peel ply off last night’s layup of the left wing-winglet lower intersection fairing.

Before I snapped this pic, I placed a red zip tie pointing at the plans (CP) position for placing a tie down bolt thru-hole.  But instead of that, I simply embedded a threaded aluminum insert with flox while glassing the wings.

In the future I’ll make up some low-drag tie-down points that I’ll install on each wing at these points.

For now I simply used my drill and carefully exposed the threads (pic 1), and then tried out a 10-32 screw to check that it threaded in nicely… which it did (pic 2).

I then stuffed the threaded insert with plastic Saran wrap and taped off the lower flanges of the wing leading edge light to protect both from the upcoming micro finish.

I then whipped up a few batches of micro (with a dash of West 410) and slathered it all onto the lower outboard area of the left wing, the inside lower area of the left winglet, and of course the added winglet intersection fairing.

I had planned on doing some more sanding on the plane, but at nearly 10 pm it was still about 90° F in the shop … so I called it a night.
