Sometimes one can't see the tree because of all the forest in the way.
I just found it. I was filling in the blanks as noted on the g76 drawing. But that illustration contains no reference to variable "j". That drawing needs edited. Now I think I can do it, but will sneak up on the depth of cut until I can see if the threads are going to match where the transition from tapered to straight occurs. I suspect it will be "close enough for the girls I go with". :) Thanks, now I can go get some sleep!
