Bob,
I use Titebond Translucent wood glue, and Elmers Woodglue Max. But actually just about any good quality glue will work. To get a good solid glue join, first you need to really clean all the gunk and crud out of the area you want to glue. If the new glue is clinging to old dirt and gunk, the join won't hold for long.
If the wood pieces you're gluing can move or shift, be sure you know exactly where they belong before you glue them. Once you're ready to glue, squirt a bit in and work the glue around to fill in all the little nooks and crannies and cracks, then squeeze everything together, and use rope, string, rubber bands, etc to clamp everything in place while the glue dries. Be careful and don't put too much glue in the crack, and clean off any excess before it dries.
