Tony says in his books to use .080" , this seems hard to find. Is .060" thick enough?

If you do, make at least a 3/8" radius on the flange. I had some spun and the radius was to tight and they would crack, some in as little as 10 hours and others 200 hours. I now make them using carbon fiber and they are bullet proof. .080 might be better than .060 if aluminum. We used generic 1/2 hard when we made ours.
