Problem: Loose chair legs. Mortise and tenon joints. You know the
routine... chair legs loosen, so you scrape out the crusty glue,
re-glue and the chair is fine... for a couple months. Soon the legs
are all loose again and the chair feels like it's going to implode any
day into a pile of kindling.

Solution: POLYURETHANE GLUE. A common brand is Gorilla Glue. The stuff
is manna from heaven. Elixir of the gods. Wood glue extraordinaire.
It's kinda expensive. Buy it anyway.

Here's quick and dirty solution that works quite well.
