I made this 48" long wind mill out of aluminum scrap I had around the shop. The 2' aluminum fan blade was found on ebay for $20 shipped. The hardware is all stainless steel. 4 7/8 bearings are used in two bearing blocks that are holding the blade and holding the windmill beam. The slightest breeze rotates the windmill and if the breeze turns a little heavier ie 2 MPH or so the blade rotates quietly. It's mounted on a 16' aluminum flag pole that is cemented into the ground. It's 100% serviceable and made with my new Grizzly G0759 mill. It's painted John Deere green and yellow.
Thanks for looking!
