I'm slipping a little. Went to HD for plates & steels yesterday. They want over $300 bucks. The guy at the desk told me that it is newly developed material on the plates. When I asked what that meant all I got was it is HD's secret. They don't want anyone to know. ???????? Shhhhhhhhhhh,,,,,

I just kinda looked at him. So what I would like to know is for the price what is the "best" plates and steels for a motor that is running 100/100+. Thanks for your time.
