Did you have any luck getting in touch with him?
I sent him an email about 3 hours ago, hope he replies. He's a great guy and phenomenal cue maker. I live a few cities over from him and have had the pleasure of seeing his work many times. I stepped away from the game for awhile (4 yrs) and am looking to start playing again, hopefully with a Webb, I refuse to play with anything else!
And yes, I'm 99% sure he cores his cues and gives a warranty to the original owner if I'm not mistaken.
