I started out busting the cases up with a sledge but that's a job so I finally went out and bought a log splitter to break them up. In just a few minutes I can have a case broken up and have a 1000 lbs of cases in couple hours down to the size to fit the my crucible. This is also a good time to remove any steel pieces that are still in the cases to prevent iron getting in the melt later. A gallon of gas used this way will go a lot farther then the same amount used to try and melt the cases down to size.
Alloy wheels are little more trouble but if you watch the style you pick up that are spoked and not a flat dished they usually go easier. Bob
How can you be sure there's no magnesium wheels in the mix?
