Everyone, Thanks for all the advice. You detailed explainations are well appreciated! Especially for clearing up the play thru out the rotation question. I will go back and tighten up the cup a little more to get rid of all play (yes will use the arms as a lever)

I used to adjust valve clearances on motorcycles and Datson Z cars and did machine work for a few summers. So I am very familiar with the effect of play in threads and how to compensate for it. Its good to have some experience
