I'd like to get a unilock jointed shaft turned down to 9.5 or 10 mm so I can play snooker with my predator. Does anyone already make these, or have any experience doing this? Would any shaft be usable? What's the best idea for size, ferrules, tips, etc.?? Can you do it all at once or better to do it .3 at a time with recovery time in between? Any thoughts or ideas would really help out. Thanks for your time in advance.
