Wind generator plans link and question

This is the link to a home made wind generator. The blade plan (click on it to download the high quality file) in the upper right is the best blade I have ever used!

The link is here-

My question is the alternator to generator system is listed as experimental. Anybody have a good design for making the change?

Looks interesting! That's a two blade design, so it will spin faster than a three blader, which normally means it will be noisier in high winds (10m/s+). Have you run it that kind of wind? We get lots of wind here - I have seen a consistent 18m/s, and that's not too unusual.

I always wonder about hand carved blades - how easy is it to get the blades to be identical (or close)? Its a complex 3d shape... how do you check its accurate?

I have seen web pages about modifying alternators, but haven't paid much attention because I make my own generators. Googling 'alternator conversion permanent magnet' should give you lots of hits.
