--for truing up jambs- lotsa times the 'rough-in' and then the installation of the windows and doors (prior to the J channel and then siding crew arrive)- the jack and king studs can dry out and warp- that's why we have shims- and the old rules are right- ie: "A level never lies", and "Always use the longest level you can"-- work-- but I wanted to get the framing square and Framingham, Mass bit worked in--first think we do with the 'rookie cookies" on the H4H Vol crews- we check their tape rules, levels and squares against ours-- a framing square with a 1" wide 16" long tongue and a 2" wide 24" long blade is a true 90% at one point, you are correct about that--and common and king rafters run off the 12" mark, jack and hip rafters off the 17" mark- thanks to some Greek dude name o Pythagorean, so I hear--
