Valley Jack Rafters, The Big Build 31
Valley jack rafters travel from the ridge board to the valley rafter, they will get smaller each time by an equal amount this is called the diminish.
I cut all the 4 sets of valley jack rafters for the roof in one go, there are 4 sets of 7 rafters and these are all matching so there is only seven seperate different lengths
I hope you find this useful.
