I just swapped out my flippers to a different color on my Deadpool. I purchased the flippers from PBL. The issue I am having is that both of the flipper bat slowly begins to move upwards. After 20 bats in move up by about a mm.
I checked the new flipper bay shafts with a micrometer and they are same thickness as the stock ones.
When I installed them I put a gap tool under flipper to ensure same height for both, I tighten the hex screw. to lock flipper in place, I cant tighten them anymore as they are very snug and I don't want to bend or break the shaft. They are not clamped down so much that there is not a gap between each plate that holds the flipper.
What am I doing wrong? Ive replaced flipper bats on my other sterns and Williams machines with no issues. The machine itself only has 300 plays on it.
