Did this condition exist with the original pins? There are a few things that will cause pins to jump like this but nearly always it is because of some manner of contamination in the block/pin interface. Before repinning, were the tuning pin holes reamed. Sometimes, just running a proper sized stiff wire brush through the wholes will clear the contaminate( this is just my theory). Oils(sweat) getting on the pins from the hands while stringing will also cause pins to jerk and pop especially if the pins drive very tightly. What kind of torque reading. I remember hearing that some guys will use powerded rosin on the pins to lessen the popping. I have always beleived that a clean pin in a clean whole is the safest way to go. Good Luck.
