The
Paterek Manual is an excellent resource, and the lug adjustment procedure is explained on page 5-26 of the new 3rd edition. As white folks suggests, the angles are cold-set using cheater bars. Cheater bars that have the same O.D. as the I.D. of the tubes are inserted into the tubes and pressure applied to adjust the lug angle.
Tim Paterek also has
DVDs that take the viewer by the hand and show, step-by-step, how to build a frame. It's like having a personal tutor, and at $89.95 is a helluva bargain.
Here's a photo from the Paterek Manual showing how the head tube/down tube lug angle is adjusted:
