Lightest coring wood?

Have you tried walnut? I have cored plenty with walnut when I need a bit lighter. Glues well, hold a thread for pins, and is pretty damn light. Plus is a great tone wood, and have rather impressive shear strength.

I have also heard of rain wood being used as a core in jump cues...but never tried.

walnut...

Hi Steve,

Don't want to go into too much detail, but you got the essence of the problem right.
Going light by coring but stable enough to hold a pin, hollow room won't cut it in this project.

Definitely not going to use balsa as it is way too soft imo. Lightest wood I can find so far that
I would be comforable with using is Koa, it is around 30% lighter then hard maple but maybe
there is something lighter still around.

Walnut seems to be pretty light???

Have you considered walnut? Walnut is quite stable. Schuler used it for break cues.


I guess you have!
