Lap Joint

July 25, 2009 by · Leave a Comment 

A lap joint describes a technique for joining two pieces of material by overlapping them. A lap may be a full lap or half lap.

In a full lap, no material is removed from either of the members to be joined, resulting in a joint which is the combined thickness of the two members. In a half lap joint, material is removed from each of the members so that the resulting joint is the thickness of the thickest member. Most commonly in half lap joints, the members are of the same thickness and half the thickness of each is removed.
