> If the tip is coming up like that when assembled,but the individual pieces rolled straight,the problem is the joint facing,either on the shaft or the butt isn't FLAT,and probably not warped.
You almost never see that on a cue with a SS joint,and if you do,it HAS to be the shaft isn't faced properly,or it was and it moved,probably due to moisture.
If this was disclosed ahead of time,it would be fine.
If it wasn't,and a cue I bought showed up like that,if I could get to wherever the seller lives,I'd be knocking on their door.
If you know someone that works on/builds cues,it's a 45 second fix. Tommy D.
