A short time ago I didn't even know about coring. I made several cues out od BE and HC and still do, ( I love the hit!) but I believe I properly season my wood MY WAY and- knock on wood- have never had a cue come back for warp issues.
TO THE ORIGINAL POSTER-
With that said, the moral of the story is not to be fooled by all of those BE and HC maple cues you see out there. If the builder used a larger core, when they turn down the tenon for the joint collar, you will never know.
Conversely, a watchful eye can look at the rings in the maple under the joint collar, and easily be able to tell.
I often ask myself, did Balabuska core?...though he used a lot of "straight grained" maple which is believed to be more stable. I don't know... but I don't think so.
Maybe a lingering 'Buska expert can enlighten me on this topic.
Hmmmm...what about Gus Szamboti and his BE cues...??? Barry??
