I have about 4000 pound of lead in one large piece, a keel cast for a boat that will not now be built. This lump will need to be cut into relatively small pieces to be recast into a new keel.
I've seen the chainsaw method and I don't think I want to go that way. It was most unpleasant and damaged the chainsaw around the sprocket housing with the sharp pieces of lead thrown from the chain.
Are there any slow and manageable methods of doing this ? Has anyone experimented with a mechanical arm on a handsaw or anything similar ?
Please tell me about any experiments you have conducted, all inputs welcome, successful or not so.
