It's done guys!!! Dan thanks for your tutorial, so cool...I was fortunate that I didn't have to un/re-screw and re-centering several times. I just rechecked and centered the tub the best EYE could SEE...then used two sandpaper sponges and some thick blankets I stuck between the inner and outer tub to keep it from moving...as I gradually tightened the nut...spun check the tub and tightened it a little more...lastly, I let it spin the full cycle and re-tightened it. I made sure I did not over-do-it, but did a better job tightening the nut this time. Now I'm allowing the epoxy the dry and harden so I can install my stop-ring for the Power-fin
