—Where the end grain is to form part of a glue joint, it is necessary to apply a glue size first.
This is done by filling the open grain of the end with a preliminary coating of thin, hot glue.
Rubbed glue joints require no clamps. The edges are jointed perfectly straight, glue is applied to each and they are then rubbed together with as great pressure as is possible to expel the glue. When this is properly done the pieces will hold together and may be set away to dry. [Fig. 142].
