Doubtful. Can't argue with truth, logically speaking. That said, i'm still gonna use my poly glue (not GG). I core a component with it and it's solid, and rings true & solid like one piece of wood. While i'd certainly agree that epoxy is infinitely stronger & a better bond, I have seen nothing about poly that indicates that it's inferior. My core fits pretty tight. It is hard to push through without the glue. The glue actually lubricates the core. There's simply no room for expansion, and as such there is no foaming. If you have foam between your core & host, you are doing it wrong, IMO.
Again, i'm not doubting at all that epoxy is stronger, harder, better in every way. All i'm saying is, at what point does it no longer matter? If somebody's having trouble with poly, it's likely their method, not the glue. A core in bore, even on a handle, is a tremendous glue surface. If done correctly, the bond is secure & the cured component pings like it's solid. There's no foam dampening the flow of energy, obviously, and apparent. So long as this is achieved, does it really matter what adhesive was used? I have followed this thread from the beginning & keep shaking my head at all the technical BS. It either works or it doesn't. Your cored component is either solid & sound, or it is not. If it is, then how do you measure "better"? Easy answer, you can't. Yes there possibly & probably is better than poly, but is it enough better to notice? I use poly & my cues ping, play great. I have used epoxy & the cues pinged, played great. The difference between epoxy & poly for me was that one I had to mix & the other I just pour out of the bottle. I found absolutely no difference in playability. I found no difference in ease of construction. I found no failure with either. More than anything, this thread looks like a "who's dick is bigger" contest. Why discount what somebody does if it produces the same end result? Just because you prefer one way over the other, or cannot find the success with one adhesive that somebody else does, doesn't mean their way isn't just as good & serves the same purpose. Look at aqua, I see blue & you see green. Who's right & who's wrong? More importantly, why does it matter? I'm the only one building Sugartree cues, and no matter how superior your adhesive is to mine in YOUR cues, I still use what is best for MY cues.
And a huge thank you to Thomas, Paul, & Royce for sharing your experience & expertise. Some great ideas were shared & it's nice to see some vets contributing......though I fully understand that doing so sometimes feels like you are being pecked to death by a duck.
