RE: Lightning Build
I made fiberglass tubes to line the holes for the canopy screws. I came up with a new method to make the tubes easier to remove after they cure. I slipped a piece of un-shrunk heat shrink tubing over a piece of brass tube. I then wrapped the heat shrink in fiberglass and soaked it with resin. Once cured, I slid the brass tube out of the heat shrink. I then used my heat gun to shrink the heat shrink, which shriveled up and came right out of my new fiberglass tube. Small lengths of fiberglass tube were glued in around the screw holes, and once cured, sanded to shape.
