im building a storage shed and want a gambrel roof?
the shed will be 12x 12 with the walls 96 inches this is with top plates and bottom plate. im having a bit of trouble finding the length to cut my trusses and also trouble with the angles to be cut. i have built a shed with a gable roof in the past.
you are essentially building a roof with 2 pitches. place your ridge. determine what you want for the front pitch, figure your cuts with a swanson square or roofing square, and do the same for the different pitch on the back.
how do you cut a truss without it falling apart? if you are building your own trusses, that takes a lot of engineering to produce the proper load bearing. did you mean rafters?
Hope that helps.

Take a few 2x4s and 4 sheets of plywood and make a temporary platform/floor on the ground. lay the 2x4s flat they are there only to hold the plywood in place, nail the plywood to the 2x4s with as few nails as possible and leave the nails sticking up so you can pull them when you are done. Mark two parallel lines 12 ft apart, these will represent the walls. Lay out a side view of the truss with pencil . You will have an exact view of all measurements, angles, braces, etc. to work from. It will be full ( 1:1 ) scale. Best thing doing it this way , you can make all the changes you want just by erasing or marking out lines and moving them. Absolutely no wood will be wasted. Just use the pattern you have drawn on the wood and when done dismantle the temp floor and use it wherever. If you have not already framed any walls, use the shed floor, just don’t forget the overhang.
