Another thought, one could use a larger screw to plug hole in ball, then oil the inside of the bore, then used compressed air to attempt a discharge? I know it’s close to another idea already said.. but I like using what I have available and an air compressor I have...another thought, I don’t know about the two part epoxy, everything has to be very clean for that to be effective enough to pull a ball. I’d not trust it, might make yet even a larger mess!
