I'll put more on this later, but This is new for me, it weighs about 3/4's of a ton. I had to hire a moving company to move it and place it. Pesonaly I didn't think they could do it, but they did, and it was HOT outside. It strikes up to 6 times per second, and can SMUSH your metal in less then that. It's a 25 LB'er. If there is interest, I'll put more pics up.
Thats an 8' ceiling, this hammer almost touches it, in fact we broke 2 flouresent light fixtures getting it in here.
