I havenít given up on this thread. I pinched a nerve in my lower back and just now feeling like sitting in front of the computer. Theirs nothing like the feeling of a red hot railroad spike stuck in my back just above my right hip. I did get a hold of the female spline wasnít some one asking for this? I havenít made it by the machinist yet and got a call in to Garrett. Oldtiffie did you want me to masher the spline like you illustrated. If so how many teeth do I skip?
