If you really want to learn how to use that thing, take one of Ron Covell's classes. I went on a 2 day seminar in Covington Ohio, and it was the best money ever spent. The classes are small, and it's all hands on.I think the cost was was $450. Best part is that a few miles away there's an awesome little bar with live music !! I was told I had a good time by the band members because they gave me a ride back to the motel. My buddy that went with me got ride back with the Ohio State Troopers. He didn't get busted, he just asked the cops for a ride, and they gave him one !! This was a few years ago, so for all I know Ron could be six feet under.
One way or another, I will learn. It'll take a while. I've been watching a lot of videos. Bought some of the Lazze Metal Shaping videos. He is an amazing metal shaper out in California who also gives classes. http://www.lazzemetalshaping.com/index.cfm. I probably wouldn't take a classroom course. Hope to get most of the theory online and the rest I will learn by just doing it.
