For the most part, I'll use Titebond Original aliphatic resin glue on stock repairs. This is the safe bet and the results will be stronger than the wood itself. easy to clean up, but requires overnight for a cured bond.
Sometimes, for fast super bonding, where the two wood pieces have a perfect fit and are clean, I'll use a quality water thin CYA such as Hot Stuff. This requires both pieces to be joined are pressed or clamped together hard, and THEN the CYA is wicked into the joint cracks. Via capillary action the thin glue will get sucked in completely and saturate the joint. This takes planning, patience, and practice as it's easy to mess up and bond skin to wood, not to mention getting the glue on places you didn't want to get glue on.
