Tell your friend that the first thing he should do is to keep a wght. bolt in the cue.
It doesn't have to be steel, it can be aluminum. BTW, what's holding the bumper on???
The wght. bolt on a Schon is critical to supporting the butt-cap.
Without the bolt, the butt-cap is subject to being dislodged.
If the cue is too heavy even without a wght. bolt, sell the cue and buy one that fits.
Don't bastardize a Schon.
