TWOFORPOOL said:First let me say that I am the "Bob" that Don referred to. When I went to Don's house and rolled the Bender butt on his table the joint did lift off the table about an 1/8". At that time I considered it warped. I ended up buying another Bender cue that is perfectly straight when rolled on a pool table and in a lathe (Greg Sowder check it for me). Greg also told me about the Parabolic taper in these type of cues could be misleading and must be turned on a lathe to verify straightness.
I then started researching Bender, SW, and Bluegrass cues regarding the Parabolic tapers on them. I verified that cues built this way need to be turned on a lathe by a experience cue maker (to make sure the cue is dead center on both ends of the cue). This prevents the misleading "warp" in these cues when its simply the Parabolic taper showing up.
Don, I think your Bender cue is in fact straight and we both at the time thought it was warped simply because we didn't understand the Parabolic taper on these type of cues. Had we both known this we would of taken it to Greg Sowder to check it on a lathe.
I recommend when you get the cue back to take it over to Greg Sowder and have him check it on a lathe. If nothing else it would give you a better piece of mind knowing the cue is infact straight.
Partner if you buy that and you are happy it really matters not. However, I can help you find some additional Cues with that taper that have the same problem. Just like your's it runs true in a lathe when between centers, the only problem with this, is that it will not show a small difference in the overall roundness or trueness. The only way to do this is to move the dial indicator over ever centimeter of the entire cue front to back.
Like I said I have seen this problem many many times. This should not be acceptable, but like I also said if you are happy that is all that matters.
