I sell quite a few cues a year and I also repair quite a few at State VNEA events...rarely do I get a totally straight shaft on my lathe when I am cleaning or retipping it. It seems to be the nature of the beast. I have built shafts for my own use with meticulous time and care in turning them down and still the wood will move. In fact I probaly did about 150 shafts at my last touney and maybe 6 or 7 looked like a laser beam on my lathe at 1500 RPM. I am sorry about your loss but I am sure Tiger doesn't even make these shafts but distributes them as their concept. Tiger is a reputable company and I think beyond the disapointment, getting back to the person that originally sold it to you might be your best bet. I have replaced shafts on cues that I have sold just to keep a customer happy and in my business who needs bad word of mouth.
