Dave, I can understand the T wrenches being needed as a special tool to lock the adjustments in place but they could have just used a yard stick and ruler to get the drops and a protractor for the pitch. I have the R. Louis Co. Shotgun Combo Gauge which does the same thing as your main beam does but is held in place by magnets.
