Cutting odd angle fittings.

Hello people. I am a trained union pipefitter and have recently transfered to a plumbers local as a welder. Some time back I had recieved on a job some paper work that gave you every measurement to cut almost any angle fitting from almost any size 90 bend. Well the paper work is begining to get old and worn and I would like to replace it with a more profesional book if such a thing exist's. Can any one help? e-mail me at This email address is being protected from spambots. You need JavaScript enabled to view it.
