hi dave,
it's not a secret that if one has at least an 18" gun drill bit, you could bore out one end, flip the cue and bore the other end and make the coring meet in the middle, then you'll have an end-to-end hole. but still, it's not easy as you can try one just for fun, and most likely it won't be straight or the wood will crack or pop. we have found a way to do it in a slower process but sure. if you really think about it, it's something like "how the hell did i not think of that!" the thing is, we do not have a gun drill bit, we don't even have a roller guide our lathe, doesn't even have a chuck in it.

how we do it, please allow us to keep it as one of our trade secrets.
oh, just wanted to reiterate for those who just tuned-in... i'm not the cuemaker. Bebot Bautista is the cuemaker. just don't want any misrepresentation.
best regards,
Les
