I cut a cue of 150cm and now it is only 70cm (I did this to fit the cue to my game room dimensions). How can I make this cue play well? Someone told me to add a heavy screw but I don't know the way to do this. Any other suggestions?
This is not a diamond, is a connection hole.
The rail hole match with the mentioned hole of surface and connected with a special screw.
