First Actual Build Step - Horizontal Stabilizer

Here are some notes on what to do when you start building your Kitfox horizontal stabilizer.

The first build step in the manual is to put together the horizontal stabilizer so I figured I’d start there. The process involves reaming holes, shaping the wooden ribs, and then bonding those ribs into place.

Some things I wish I knew before I started:

  • Grind the end the holes on the leading edge of the tail are incredibly hard to get to grind the end of your reamer so that it can fit into a socket. Then use a universal joint to allow for a drill to be used to drill a hole. This would have saved me hours and this trick comes up again frequently.

  • Get at least spring clams pony clamps to hold ribs in place and two 2 ft scrap pieces of 2x4 to prop up the horizontal stab portion.

  • Try to avoid grinding the leading edge of the ribs to get them to fit. Just grind the trailing edge.

  • Use a syringe to apply the Hysol, and make nice filleted corners.

  • Clean up sloppy Hysol applications with denatured alcohol before you let it dry.

  • Keep a close eye on the stiffeners as they may fall over or lean.
