Fiberglass work on HS tips

Jared came by with all of his fiberglass stuff and showed me how to close out the horizontal stabilizer tips. I am so grateful to have someone who built the same plane as well as a couple of others that’s willing to help me out as I am learning to build my first plane. Thank you Jared!

We started by attaching the elevators to the hs on the bench. I drilled and clecoed the elevator tips that I had trimmed and fit yesterday to the elevators. Then we trimmed and fit the HS tips to the horizontal stabilizer. We drilled and clecoed them in place and trimmed the trailing edge to match the profile of the leading edge of the elevator tip with a 1/8″ gap.

Then we trimmed and fit the HS tips to the horizontal stabilizer. We drilled and clecoed them in place and trimmed the trailing edge to match the profile of the leading edge of the elevator tip with a 1/8″ gap. We removed the tips and cut out a foam backer and sanded it to fit into the HS tip.

I traced the inboard edge of the tip on some glass cloth and cut it out with shears.

We used West Systems epoxy with the fast hardener. First we mixed up a batch of epoxy and incorporated glass micro bubbles into the resin to make a thick paste that we used to glue the foam in place.

Then we mixed up another batch of epoxy and laid the glass cloth over the foam. I used a brush to impregnate the cloth with resin and set it into place. It’s rare that I get a picture of me actually building my plane! Photo credit to jared. I had the mask on to work with the micro bubbles. it’s powder fine and super light so it disperses into the air easily and probably isn’t very good to breath.

And here are the HS tips setting up. Once they’ve cured I’ll fill them with micro and sand them to match the profile of the leading edge of the elevator.
