This thread is full of crazy talk.
I have a cue from a custom maker with the entire butt and shaft cored with phenolic rods.There have been two places where you would think the shaft is cored.
1st..... A small rod under the ferrule inside the wood.
2nd... An insert of whatever you want inside the joint end. Some Cue makers use to use different woods here when a shaft stripped out before they realised how much stronger phenolic was.
WOW , Seriously, thread coming full circle.I have a cue from a custom maker with the entire butt and shaft cored with phenolic rods.
Watch the new McDermott video.they put carbon fiber rod in front of shaft.I just had a look at McDermotts website in case they have launced something new. I can't really see a cored shaft. I see the i series with a carbon fibre core just like Mezz Hybrid Pro II or EX Pro. Is that what your looking at?
That maker claimed he used phenolic tubes .
