Aerolite glue: What kind of glue is it, and what would the European equivalent be?

Dado set: I don't recall I have ever seen this (but then again, I am not a woodworker). If this method is not common on this side of the world, what would be the appropriate way to achieve the same result?

A dado joint is a means of joining a part at right angles to another at some point on its surface other than the edge. A dado set is a set of two circular saw blades with opposing relief angles and several chipper inserts and shims that mounts on a table saw. They are stacked on the saw arbor in various thicknesses to produce a flat bottomed groove called dado. You should be able to find them at any half way decent woodworking store anywhere in the world. Largest international manufacturer is Frued. See http://www.woodmagazine.com/woodmall/charts/dado_sets/

A less expensive but very poor substitute is the wobble type dado blade. It is a single blade mounted on an adjustable collar that sets the blade at an angle to the arbor so that it wobbles across the width of the material.
