On Friday 16th October 09 we were back to put the turbine back in action.
The nickle plating had come off the front of the magnets, this could have been caused by electrolysis and if that is the case then the magnets are going to end up being scrap and will need replacing.
So after much debate we decided to just clean the face of the magnets and paint them with epoxy paint and see how long they last, if we get another year then that would be good.
The main reason they rusted was the use of polyester resin as this lets the water in. The next time we will recast the magnet rotors using vinylester resin and new epoxy coated magnets. This turbine was made when the properties of polyester resin weren't too well understood. We use epoxy coated magnets and vinylester resin in all our turbines and never had this problem.
A nice new tail was made with a grand paint job done by Iliocht and his talented artist friend Harriet Myfanwy Nia Tahany
The prop was painted with undercoat, it worked well for the last two years so why reinvent the wheel
