I'm gonna have to seal them with epoxy and then some paint to make them last a long time in the weather and prevent warping. The wood is just some clear pine from the local mill. cost me less than twenty bucks. Alot of work tho, I reckon now that I know what is involved I could maybe make one blade in two days.

Would you seal them with linseed oil or varnish?

Hey Nick, got my blades to near finishing stages now. I'm a bit daunted by the size of them! The thought of these 1.2m babies whirling at 7 times the speed of the wind... It's gonna be a hell of a mess if one of these come loose.

Hey Fellas,
Someone sent me through this: www.HomeMadeEnergy.org - based out of the US- it is a $75 NZD manual for making your own solar panels for under US $200 and mini wind turbine for US $100 from stuff you can buy from your hardware store.
Looks a bit pyramidy, or could be a good project for any keen young peeps with some time on their hands, to see if it if use and how it could be adapted for NZ conditions/ materials availability.

Hey Nick, Yeah I'm working away on a 3m Diameter turbine, Wooden blades with the intention of creating a hydraulic direct mecanical-mecanical energy system. It's taking a while though, I always get distracted by gardening priorities, getting there... The best tool in the world for carving curves for turbine blades is a thing called a Stanley:SureForm.
