How do you cut rafters with different plate heights?

Answer:

If the plate height gets higher increase the depth of the birds mouth that sits on the plate. The birds mouth is the notch cut out of the rafter that allows it to sit flat on the top of the plate. If the plate is low then you will need to place a packer on top of the plate.
