RE: Making a nose cone mold for an Explorer 2M glider
Next I did one layer of regular laminating resin and 6oz fiberglass cloth to finish the outside of this mold half.
Another tip I got from my visit to Polymer Composites was that I could speed up the hardening process by placing the fresh epoxy and the mold under a 40watt light bulb. Since I had my heat gun handy I just warmed up the resin from about 12” away every 2 or 3 munites until the resin setup. I only got it warm only, not to hot to where you could not touch it.
