https://www.cuefits.com/index.php?route=product/category&path=67_69 I went to cuefits and replaced the pin on my Jacoby and bought new bumpers for all my cues to fit
Been a while since I owned a Schon. I dont know if the threads would be long enough.You would need to make a spacer at least. Cuefits has a number of bumpers/adapters you might use since they have them in different lengths. Might be cheaper also since the Jacoby one is 50.00
