Quoted from Jason43:I think I'd just opt for a new insert instead of re-using the original. I kind of like the idea of a clear star insert, even if I'd have to hand draw the keyline art. I've never removed/installed a star insert. I take it that given their nature, they're tough to work with without breaking?
You would be surprised at how little you will miss the black keyline that was around your old insert. Your play action will have improved so much you will be more busy tracking the ball across the play field than checking for some black line.
The easy and only real safe way to remove the star from the insert is to cut the mushroomed bottom of the star off and slide it out of the insert. There is very little risk of breaking the insert when installing a new star. Stars cost around a dollar each and I was having good luck just knocking them out of the insert---until my luck ran out and I broke an insert. So, now, for a dollar a pop, I keep several extra stars on hand.
