Hi Richard.

Sorry it took me so long to reply to your post. I've being meaning to measure up one of the blades for a few days but always forget while I was in the workshop.

OK, here goes. The root is 150mm wide, the tip 18mm wide. The mounting tab is about 60mm long, 35mm wide, 18mm thick and has two 6.5mm mounting holes. The blade length from tip to root, but not including tab, is 650mm. Diameter of a propeller would be about 1550mm, give or take.

They are a high speed blade, not a lot of starting torque but run fast once going.

Hope that helped.

Glenn.

Just adding, I think these would work on the Chinese windmill. They should spin a lot faster, so the cut in will be earlier and you may end up with a good little windmill.
