Trimmed the horizontal stabilizer fairing to match the elevator fairing angles. Left enough gap to fill and sand.
After that I put in a foam rib as called for in the plans. Used some 5-minute epoxy to glue it in there. However, I will not be removing it as the plans call for. I will be filling on top of the foam rib with some West Systems 410 micro light filler and sanding to make the edges nice and rounded and form fit to the elevator fairing.
Placed the first layer of filler over the elevator seam. This is once again the 410 filler. After this cures it will be sanded. Then I’ll epoxy a 2 ounce strip of glass over it to prevent the seam from cracking later on in life. Then I will fill over top again with 410, sand it, and prime. We’ll see how it turns out before I do the left side.
