Making small GRP Wind turbine blades

[Jonathan]

This is the blade I made a few days ago, got my sister to help with laying up the resin/glass:







It went reasonably smoothly. The blade came out of the moulds easily, however it had collapsed a little in one area. I've since built that back up with more resin/glass and sanded it a bit, so now you can't tell. A bit of wax came off the mould with the blade so I'm currently waiting to get some more before I can make the next blade.

The blade itself seems strong, it doesn't bend much except near the tip. I might fill it with polyurethane foam just to make sure.

Oh and thanks to 'Chip' for giving me some resin - I used a little of it here since it said on the container that it did not require gel coat.

Now I've got to paint it - any ideas where to start with that? Some sort of primer then white paint I suppose. I think the spray paint used on cars would stick?
