Quoted from vid1900:Remember also that the existing indentations in the shaft will often **find** the setscrew tip and return the flipper to the wrong position.
Sometimes the only fix is a new shaft.
Swapping the left and right flipper shafts usually provides a fresh place for *one* of the screws to bite into. The other one may line up half-way with the old indention and want to pull it into there with the screw point, so for that one you can install a flat-tipped screw and just let it bite the half of the post that's there.
But I agree, replacing is the best option. Just MAKE ABSOLUTELY SURE the flipper is in the correct position before cranking down the screws and putting a divot in the flipper shaft. It's pretty much impossible to fine tune that position with pre-existing divots in the shaft.
