	I can't remember the formula used to lay out a notch in a pipe to bend and braze it. I'm building an intake manifold out of 1.5" "type L" copper and I need to make 38 degree bend in a close quarter area, and with the price of copper I can't afford to many mistakes.LOL. Any how I've tried to model the bend with thin wall EMT and PVC but they don't have the same bend characteristics as copper with an avg. wall thickness .062". If anyone has a suggestion I'd greatly appreciate it. Thanks __________________ Confucius once said, “ Ability will never catch up with the demand for it".

	Didn't you just ask this same question earlier? http://cr4.globalspec.com/thread/37250/Pipe-Bending-Formula-Notch-and-Braze Most of us that have been here a while sift through the posts pretty thoroughly, so posting again that quickly is just spinning your wheels. My experience has been bending SS tubing; to do that you need a tubing bender specifically for the same diameter of tubing you are bending. Have you tried a Google search? That might yield some more results. Mike __________________ "Reason is not automatic. Those who deny it cannot be conquered by it. Do not count on them. Leave them alone." - Ayn Rand

	I can't use the standard pipe/tube bending formula r=>5 xOD. Like I said this bend is in close quarters other wise I would use a "tube bender" Thanks for the comment __________________ Confucius once said, “ Ability will never catch up with the demand for it".
