how to notch pipe
I need to cut a notch in the end of sched 40 3.5 inch pipe to allow 2 inch
pipe to pass through it. Available tools are reciprocating saw, drill press with bits up to 1 inch and bimetal hole saws, and cutting torch. What's the best way to do it? The notch needs to be snug because the 2 inch pipe will be welded to the 3.5 inch pipe using stick welding. Mike Note: To email me, use the address below with the q's removed: |

The notch needs to be snug because the 2 inch pipe will be welded to the 3.5 inch pipe using stick welding. Single hole or a few? Hole saw and some frustration getting the "plug" out of the unit. Use a sturdy drill press or milling machine to hold the pipe and drive the hole saw. Many holes? Check out Hougen's holesaw-like tools. They automatically eject the plug so you can go on and on... I can fax you a page from their catalog if you eMail me privately with a contact number, etc. Regards, Joe Agro, Jr. (800) 871-5022 http://www.AutoDrill.com http://www.Multi-Drill.com V8013 |

If so, cut a pair of 2" holes opposite each other in the big pipe, then whack off the end (if you really want something called a "notch"). This will waste a bit of your big pipe, but not much and it'll be a nice notch. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com |

If you've got a good bimetal hole saw, and your drill press will run at the appropriate speed, and you can clamp everything down solidly, then that's the way to go. |

If your good with the torch the somewhat jagged hole will be welded up. Much less effort than trying to secure in a drill press. Also you didn't mention how long the 3.5" pipe is. Might be tough to wrestle into position on a drill press. Regards, Bernd |

You even quoted his tools list in your post. Refer back to the bit that says "cutting torch" just a couple dozen letters past the bit that says "available tools" :-) Cheers Trevor Jones |
