There are 3 different types of cast iron pipe snappers I am familiar with. Manual, with two handles like a set of bolt cutters. Ratchet, one handle that ratchets and tightens the chain. Hydraulic, you pump the handle on a cylider to tighten the chain.
Then there is the hammer and chisel method. Mark around the pipe and follow the line with a chisel. Lightly at first and harder with every round.
Grinder. 4" or 7". 7" is harder to control especially if you are cutting a vertical pipe. Both grinders will "hang-up" if tilted while cutting. Always wear safety glasses when using ANY method to cut cast iron. Good luck.

You could also use a Saw-zall, just make sure you have a lot of metal blades.

Thanks for the advice. I picked up 2 sawzall grit blades that are labeled for cutting through cast. I'm hoping they will get me through the two cuts I have to make.
