Spreading epoxy on gussets and rib cap strips

The Baby Great Lakes is a small biplane and because it's small so are the wings. The wing cord is 36" and the jig itself is only about 38" long so I elected to build the ribs on the kitchen table.

This process is so simple that I won't write much about the process. What I will do instead is right down a few notes on what to look for in the photos.


  • Acid brush to spread epoxy. I bought a bag of a hundred at Harbor Freight. I cut the bristols short with a scissors over a trash can so it became stiff enough to spread epoxy.
  • Epoxy both sides, the gusset and the cap strip.
  • See the pencil marks? 
  • See the nail divots in the cap strip? That makes the mating process so simple you don't have to think.
  • See how the nails poke through?
