cutting a 4

I have expenienced 6-7 times of main drain block since I bought the house six years ago. I hated to pay $70 to Roto Rotor each time as I already did to clear the block. So I want to insert a PVC T with an outlet to let my power snake get into the pipe. The T will be next to the wall of the house. But I have to cut a segment of the 4 inch cast iron pipe under the ground in order to insert the T. What is the good way to do it? I already asked the local rental centers for a chain wrench pipe cutter but none of the centers has it. Any advice (I have 7" hand held grinder, 7 1/4" circular saw with metal cutting blade, propane torch and some chisels)?

Probably the easiest since you can not get the chain cutter is a sawsall. A metal blade in a skill saw would work as well. Do not use a chisel, hammer of anything like that. A torch does nothing to cut cast iron. Cast iron is brittle so be gentle and use something that is designed to cut metal.

Good Luck
