I'm doing a 4/12 roof (my first attempt without trusses) and I know I need a birds mouth at the bottom to sit on the top plate...
But won't that throw the 4/12 angel off at the top? how do I adjust for this? and how deep should the birds mouth be cut? or does the 4 common acout for a birds mouth on my speed square?
please answer soon it's gonna rain soon!! (joke)
thanks alot for your help,
Chad B
