Wonderful graphics Jakob! and the process you described is very similar to my mine. In the images I posted I am at the ~1mm from where it should be. I try to remember that because of the radius of the arc, the edges of the finale move slightly forward each small step it goes downward.
I agree Ron! Jakob did an excellent job depicting how you teach to inlet a butt plate. This mimics what I imagined in my mind while you explained it it me.

You can do it! All of the advise in this thread is spot on. Go slow, stop if it does not "feel" right and think about how it slowly curves into place.
