Im trying to get a fairly straigh cut on the cast iron 2 inch pipe that I accessed through a hole in the concrete foundation. Short of making the hole entirely to large to use my saws all, I don't know what to do!!

Still trying to get that Twist-N-Set flange to fit right? You can chisel the pipe at the floor level or put your SawsAll almost horizontal and use some pressure to bend the blade just a bit to make it slide back and forth on the concrete. It will wear out the blade a bit more quickly but you will get your flush cut. I have an old Sears reciprocating saw that allow you to rotate the head and do flush cutting, that's all Iuse it for now.

Nope not working on that toilet now. I got that where I need it until I get the floors in. Im working on the bathtub right now. Had to move the shower drain over a bit to fit it to a bathtub. I have the hole cut in the concrete, but I have to cut the cast iron pipe down a bit, so the saws all won't get in there. I read in another thread about the cast Iron rachet cutter. Someone said you can rent it?? Not sure.

Yes, that's a tool that you can rent for just a few hours. You will not need to trench very deep around the pipe so it won't be too difficult. Ask the guy at the rental store to show you how it works, not hard at all but I'm not sure you need to do this. Now you could just SawsAll that 2" drain line by digging a shallow hole for the blade to go back and forth and then transition to PVC with a Fernco coupler.

Hey guys... one more idea.

Could also use a die grinder (see pic.) with a diamond wheel. You may need to make this up...

Or could use an inside cutter tool (see pic.) and regular drill and change out the pvc cutting wheel with a diamond wheel.. and then cut on outside of pipe... ;)

Both these options will keep you from opening the floor too wide! Otherwise, sawzall is best option here (lennox makes a NEW diamond sawsalll blade that will cut this in two or three minutes! ).

Bob's right... DON'T use the ratchet snap cutter here... not worth the time/effort.

Never mind could crush the pipe... requires more room then simply using sawsall below floor (have to move the lever arm in an arc of motion that exceeds what you might expect).

Let me know what you think... Mark

Thanks so much for the train of thought. I was able to dig a big enough trench under the foundation so I could fit the saws all down there. A metal blade for the saws all cut through it in about 15 minutes.

I just needed ballengerb1 and massplumber2008 to put me on the right path. I wish I would have had that diamond blade, but Its done and I'm glad.

Thanks a bunch.

Let us know if you need any help with making the transition or anything else. Bob
