i think i got a sucky miter box, my hack saw cut right into the miter box, i think the problem was the pipe was taller then the box, i think i might just go to homedepot and rent a compound miter elctrical saw for 30 bucks and cut up my 5 ft 2 inch ABS into a bunch of drift tires, so i wont have to deal with cutting poly pipe, not sure might try to find a taller miter box first
