Ok, I have done and extensive search on Pinside, but cannot seem to find direction for modifying Cointaker's Color Changing shooter Rod to work with Stern. The way I understand it, a coil sleeve must slide in the shooter rod housing to insulate the rod from the housing so it does not short. With that said, Cointaker has no instructions on how to do this. Do you simply drill out the original housing the size of the sleeve so the sleeve can be inserted? If so, what size bit do you use? Thanks in advance!
