If the rafters are in the plane, then calibrate the bars and plank crates on the machine. And so, we deduce laths in the plane of the screws 6 * 80-120 with a full thread (there are such, without a smooth body). Lattice remains threaded on the screw threads at the required distance from the bar. On a thread straighten the top and bottom battens, and then move the slope of the rule from the board rib and align everything else.
