Does anyone know how or where to find theformula to layout coping cut lines on pipe. I might be saying it wrong so please don't poke too much fun at me. I know about the mitre programs on the Internet,but I don't have a computer or printer in the shop. Thanks again

The search at the top of the page will give you a ton of info. Here are a couple of threads that go into a great deal of detail on it.

How big is your pipe? If the pipe is small for handrail, there is tricks to use with out calculations. Im guessing the pipe is larger? Layout will be needed in that case.

The second post in the first link supplied above is an excellent way of finding your copes for both pipes. That is what they teach in fab school.

What sizes of pipe are you looking to cope? Also what angles will the pipes intersect each other?

It is for 1 1/2" and 2" pipe. Any short cuts or formulas would help

If you are going to be in the trade, pick up the pipe fitters handbook as has been suggested already. No formula is required, but you have to have an understansing of pattern developement before you could possibly understand a written explanation without first looking at a sample layout. Until you pick up a copy of the handbook, you could google 'pipe layout' or pattern development'. The pattern will change with each pipe size and different intersecting angle, so it is a good practice to transfer your pattern onto light gauge sheet metal, or other durable stock for future use.

templates are great, but you still need to have an understanding of how those templates were made. get the pipefitters handbook, learn and reference it when needed, then make your own templates. you cant always rely on a computer to be on the jobsite.
