Making small GRP Wind turbine blades

If you do, make sure you put it back in the mould while it sets otherwise the resin may cause it to bulge.

Yes I was going to do exactly that.

Are you going to be making many of these? If so there's some ways you can make the process more efficient.

I might be - depends how well these work. What are you thinking of? I guess I could use prepreg, but I'm not sure where to get that. Not really sure what else without adding significantly to the cost, other than using thicker cloth to reduce the number of layers.
