Great to hear you got it working properly. How's the trigger pull now ? Should be able to get it down to 3 lbs easy enough.

I would put the ball back on with a bit of JB Weld or epoxy. Wash both parts with lacquer thinner and the use a Q tip to rub the epoxy on the inside of the ball and on the shaft before putting a small blob inside. It will give you a better bond.
