Re: Re: Rock crushing
A good method of breaking up big boulders is to use feathers and wedges. Drill some holes in a line, then use the feathers and wedges, tap lightly with a hammer up the line until the boulder splits. I have used an electric roto-hammer and an electiric generator to drill the holes. Holes can also be drilled using an air comressor and drill, or by hand which is a lot of work. A hydraulic press can be used to split smaller rocks or specimens to minimize damage.
