I have seen CA hinges that have a "Wick channel" (ie a slot cut into the center of the hinges to allow the CA to seep into the slot better) and I thought it was such a good idea, that any time I had hinges without them, I started drilling a hole in the hing slot. Imagine mt surprise when GP started instructing you to do just that! Answer is: Yes, drill the hole.

Remember, even though the hole may have sawdust in it, the thin CA will still wick through better than if there were just a slot!
