Heres a Vid of the baby in action going to work on an old alternator I was going to take to scrap. http://www.youtube.com/watch?v=bS47JZl--Qs
I'm half Inclined to take the thing up the wrecking yard when I visit in a couple of weeks and try it on an engine just for chits and giggles. I reckon I could knock one over in 30 Min without much problem.
Might have to set it up on some wire to let the ally drip through and catch the steel bits. Might even make an interesting bit of wall art for the workshop.
