Introduction
Wooden structures such as tables, chairs and cupboards consist of a number of wooden parts that are fixed together in a way that forms a rigid structure.
The traditional way of permanently fixing pieces of wood together is to bond the parts using an adhesive.
Wood adhesives bond to the sides of timber very well but do not bond well with "end grain". This is because end grain is very porous and absorbs the adhesive.
Timber joints that rely on bonding to end grain are generally weak.
Wood joints are solutions to the problems associated with gluing to end grain. |
