Chainsaw blades: finished product

[imsmooth]

I finally finished the blades.  I used a chainsaw to carve the initial profile.  I used epoxy paint to rebuild areas in order to get a good profile, and protect the blades from the elements.  I coated the epoxy with automotive clear coat acrylic spray paint.  The blades are 5' 1" long, 10 1/4" wide and 2 1/2" thick.  Each blade weighs close to 3400g.  The rotor is 10.5' in diameter.  The final images are at the bottom of this link http://www.mindchallenger.com/wind/wgpage15.html

I just hope they work.

With all that work I doubt you will see much more power than if the blades were rough but I bet they will be a LOT quieter as a result of being real smooth.

I spent an extra few hours on the final sanding, filling and painting on mine and I'm convinced thats why I can't hear them from 100' away.

Finishing my blades caused a few ear bashings from the missus {to be fair i did spend a long time on them in total as I had no power tools} but I was convinced it was worth the effort. A friend of mine has a small 3ft 6 bladed production turbine about 120ft away from me and I can actually hear his turbine over mine!
