Hi All. I've started on a page about my modifiactions of the Chinese blades. Its not completed yet, but worth a look anyway. I've finished my blades, just waiting for the paint to dry ( I should have read the can before I sprayed the blades, touch dry in 8 hours ![]() So I wont get the blades mounted and tested for a few days yet. The page address is http://www.thebackshed.com/windmill/articles/chineseblades.a sp There are no links from the main site yet, not until I've finished the page and have some test results.

Hello Glenn. They look something like the "art" blades I got from a chap in America. they were f/g and I did a bit of finishing on them . I found that on the old F&P they were a bit narrow ,I think , but maybe I'll hoist them up again ,now that I have the non-cogging rotor ,maybe ,, I think they were about 3 foot 6 inches by around 4 inches at the root and just 2 1/2 inches at the tip-- I mounted the adjustable blade holders onto a 12 inch Al disc to give a dia of a bit more than 7 feet, Oh, and these were a bit noisy also. Be watching to see how your set performs Bruce Bushboy |

Excellent work. The cut off disc should be for 'stone'. Not steel. Or better still, a diamond saw is the best. Glass is derived from silica sand, it will make any teeth type saw blunt. Trev @ drivebynature.com |

I was surprised how easy it was for the angle grinder to cut throught the fibreglass, like a hot knife through butter and very easy to follow the pencil line. I could see a orange glow inside the cut, but no flame or burn marks, lots of foul smelling smoke though. I've given the blades a coat of paint, then sanded with wet and dry paper with water, and repainted tonight. This got rid of all the little fibreglass hairs.
