Comparably, the best, and possibly the most arduous work in
wood joining is done by gluing. Anyone can do an average gluing job without much
thought or trouble; but a suitable, lasting joint, even stronger than the wood
itself, can only be possible the right glue is used and if the glue is applied
properly.
The effectiveness of a glued joint is determined by (1) kind
of wood, (2) its moisture content, (3) type of joint, (4) precision where
contact surfaces match, (5) kind of glue and the method of its preparation,
handling, and application, 6) level and length of pressure used when setting,
(7) process of conditioning glued joints, and (8) service conditions.
Basically, heavy woods are harder to glue than light woods;
hardwoods are more toilsome to glue than softwoods; and heartwoods are more
difficult to glue as compared to sapwoods.
There are eight types of commonly used glues available
commercially. Of these, the first six are especially useful for the home
carpenter: (1) liquid glue, (2) blood - albumin glue, (3) casein glue, (4)
synthetic resin glue, (5) vegetable glue, (6) rubber compounds, (7) cellulose
cement, and (8) animal glue. There are a lot of ready-made glues on the market
that are user-friendly, but the hobbyist would want to know about some of the
glues utilized by professionals.
