   A cut off wheel would work. My plumber uses them occasionally. I'm assuming since you need to cut it your gonna add onto it. How will you be able to set a Fernco if you dont have room for the cutter?

   I hate Fernco¯ friggin things can't hold a 2 story test on a horizontal pipe------- my crew has become experts with wet vacs.

   But, back to the point of fitting a coupling in a tight location.

   If there is atleast 3/8" gap between the pipe & the wall, stud, block etc...... then rolling a coupling will work just fine.

   My point was that if you have 3/8" you should / may be able to get the cutter in there.

   Not sure what cutters you have, but mine the chain is 1" in diameter.

   I dont have one. I guess its been a while since I rented one. They are a bit wider than a Fernco.

   Its still gonna be tough to cut with such small clearance.

   Why not just sell the house? :>)

   So, you started with 1 20' PIECE and ended up with a 100' (5 20' sections). So that stuff really does multiply, I always thought it seemed like it did!

   If you are going with an angle grinder, I'd go for one of the thinner wheels for cutting metal. Peruse http://www.lehighvalleyabrasives.com/servlet/the-template/developmentsinabrasivesandrightanglegrinders/Page for example.

   I've seen plumbers use a grit sawzall blade (diamond maybe, or carbide?) which they get from plumbing supply houses.

   The special cast iron recip blades cut well. Also other than the snap cutter, the fastest and cleanest cut is a portable bandsaw, that cut very quickly. Whatever method, make sure you have the upper part supported well, it doesn't need to move much to pinch your blade and get you stuck.

   The torch blades from Milwaukee work fairly well. I think I'd reach for one of those before a cut off wheel.

   last year i had to cut a pipe under the house, i did not have a chain cutter but just used 6 sawsall blades to cut it, i used all my dull ones so it was no loss. worked fine

   The first time I did it with a diamond blade, it works but is overkill. A thin cutoff wheel works fine. On my 4" Makita grinder a Norton wheel, like they have for a buck and a half at Home Depot, will do one 3" cast iron pipe.I needed a bushing to hold the Norton wheel centered in a Makita but I found a washer that works
