Here is a simple, strong way to make very light v-tails - or any other item that needs
strong, light, flat surfaces.
- 1/16" 4-6 lb / cu ft contest grade balsa.
- One or two 3" foam rollers
- Some waxed paper
- A couple of pieces of glass for rolling and weighting
- Pour a puddle of thin epoxy onto wax paper (putting the wax paper on a glass sheet makes
the next step easier)
- Run a 3" foam roller through the epoxy puddle, then roll the balsa
- Apply 0.5 or 0.75 oz fiberglass cloth evenly over the surface
- Roll the cloth onto the balsa, on both sides
- Sandwich the fiberglass/balsa between two pieces of waxed glass, and weight down flat
(you don't need to vac-bag this...)
- Don't be too anxious to pull it out quick - leave the sandwich weighted for at least 24
Note: We do whole sheets of balsa at a time - then cut out your surfaces
with sharp scissors and sand the edges
This produces tail surfaces that are only slightly heavier than 3/32" balsa with
lightening holes (covered with transparent Ultracote), but these glassed tails are very
durable and good looking to boot!
