Mitch, a method I like is to pour the pitch onto the tool (about 1/4-inch thick), made of plywood for example, Hot press to curve, then use a soldering gun with a 10 or 8 gage wire in the ends (stiff copper) and use the gun to score the lap. Tip the tool up to let the hot pitch run out. Now hot press the tool again as many times as required.
