Could a small, butane pencil torch(2000F)cut through a steel pipe between 1/8-1/4in thick?If not, got any suggestions? Answered

I need to know this to make my first Instructable, so any help with how to cut this would be appreciated.

I don't think so. How about a hacksaw?

I second hacksaw. It's cheap and it works

Get a reciprocating saw (Sawzall) with a bimetal fine tooth blade. That is what plumbers do if the wall of the pipe is that thick. You must have an 6-8 inch diameter drain pipe that big.

If that was 1/8-1/4 diameter pipe, they make tubing cutters that is a small hardened cutting wheel you clamp tighter and tighter on the pipe, twirl it around and it will cut the pipe for thin-walled metal tubes.

If your not worried about the edge of the cut a dremel with the fiber cut off blade can do it but it will take some time.

Nope. Even a large butane torch won't cut steel pipe. An oxygen-acetylene torch (3500 F?) cuts steel by heating to the melting point, then a jet of oxygen oxidizes through the metal. You need a lot of heat, localized in a small area. A 14 or 18 tooth/in hacksaw is probably the only way that doesn't involve lots of equipment. When done properly, a hacksaw isn't terribly slow though it does seem to take forever. (Not too fast, about one stroke per second, raise up slightly on the reverse stroke.) Prfesser
