Builder David Kragnes has sent two useful topics. First, after reading about Mark Richardson’s process for making wingtip light mounts in the Fourth Quarter 2025 Beartracks, David sent in his process. He embedded a piece of plywood into the fiberglass permanently. David writes, “I traced around the light on plywood, 3/8 is thick enough, then cut with 3/16 inch extra around the shape. Next trace the shape to the fiberglass wing tip. Align with the center line, then use a die grinder to trim out the tip to the plywood shape. Be careful to make a tight fit. With the outside of the plywood flush, mix up some epoxy and thickening to make a filler around the inside and outside. Sand to smooth transition. Light, strong, way less work than making a form then a faring.
