: AN ANALYSIS OF TENONING, MORTISING, RABBETING AND BEADING
The lap-and-butt is the form of uniting members which is most generally used to splice together timbers, where they join each other end to end.
Bolts are used to secure the laps.
But the lap-and-butt form is also used in doors and in other cabinet work. It is of great service in paneling.
A rabbet is formed to receive the edge of the panel, and a molding is then secured to the other side on the panel, to hold the latter in place.
