Making glider composite parts requires time, and timing because epoxy must first cure.

Before I went to bed last night, I layed up fiberglass on simple molds to make various closeout panels.

The epoxy cured while I slept, at least enough to de-mold.

Now the parts are sitting on the glider trailer and getting warmed by the sun. In a couple hours they will be fully cured.

For some glider fabrication jobs, I want the epoxy to cure faster...so I heat it in the microwave.

Seven seconds, mix it to even out local hot spots, seven more seconds, mix again...then apply. (For a small batch...approx 20 grams.)

I think the microwave radiation doesn't merely warm the epoxy. I think it somehow also accelerates (far more than a few seconds of warming would) the curing chemical reactions.

I only do this for epoxy jobs that are NOT structurally critical.

A cup of epoxy, mixed with thickening agents, briefly heated in a microwave oven. This greatly accelerates the curing process, but I don't know how it effects final cured strength.

Goblin's Hoard Dice

I rarely repeat designs. I take inspirations from past designs, I tweak them, I keep experimenting and playing but I rarely is there a set that I just want to replicate (as much as that is possible with the fickle nature of resin). But I can't stop thinking about this set since I've pulled it from the pressure pot ^^
So what do you think, is it worth it to try to create another one of these? 💙
