As for perforating the wood for glue penetration, I'd only do that in an attempt to make Gorilla Glue or other foaming type to work. The voids being created only decrease the surface area to be bonded. I'd much rather scuff with sandpaper.
Sorry sir, there was no intent to be offensive. I happen to use aliphatic glues almost exclusively. Well except for sheeting foam wings - that gets Gorilla Glue and on rare occasions CA is used to start some project but rarely if ever to finish it.
As for the "voids" reducing the surface area I think we might have a slight disagreement because I think they INCREASE it since you are adding surface the glue can latch on to. Use what works for you, and I have found that in almost all cases where I was building a joint and wanted shear strength, the extra 'fingers' helped. Of course I am nuts and will do it MY way! LOL.
Oh, what the heck is a "luthier"?
