Loose Tongues
:
THE TONGUED AND GROOVED JOINT
There are two methods of jointing with loose tongues, viz., the use of the cross tongue, , and the use of the feather tongue, . Cross tongues are the stronger when glued in their position and can be used very much thinner than feather tongues. Feather tongues are cut diagonally across the grain as illustrated.

is a cradle for planing up loose tongues to the required width (generally 7⁄8 in.). Two grooves are made in a piece of 11⁄4 in. hardwood; one groove is used for planing the width way of the tongue and the other for planing the edge way. These tongues can be cut to accurate size on a circular saw bench if power and machinery are at hand.
