buttress threads

(OP)
i guess i have posting my questions on the wrong feed, but i hope someone here can help. I know that in the mechanical handbook there are equations to find the geometry of a buttress threads, but they are only for standard 7/45 threads. would anyone have any information on where to find equations that can be applied to any buttress thread, possibly based off of the lead angle of such thread?

RE: buttress threads

(OP)
thank you. that is a good starting point although I am looking for a little more info on the equations behind the 10 deg buttress and 3 deg buttress. i know that most of the equations used in the 7/45 are related to pitch and the lead angle, but can not find any information on the equations for a 10 deg.
