Open or Through Joint
• The Open or Through Joint is similar to the Half Blind
Joint except that joint seams are visible on the front, back,
and sides of the workpiece; on the Half Blind Joints, the
seams are visible only on the sides of the workpiece
• Although this style of joint can be also used for drawers,
its most popular use is for making boxes, and small and
large chests
• The height of both the front and the back of the drawer
or chest is the same height as the sides of the drawer or
chest; and the length of both the front and the back of the
drawer or chest is the same as the width of the drawer or
chest
See Figure 40

NOTE: THE DEPTH OF CUT IS DETERMINED BY THE
THICKNESSES OF THE FRONT, BACK AND SIDE
PIECE&
• The front and back pieces (sometimes called "tail
pieces") are cut independentIy from the side pieces (some-
times called "pin pieces")
- The "pin pieces" are cut first using one edge of the tem-
plate and a dovetail router bit The depth of cut is equal to
the thickness of the "tail pieces"
• The "tail pieces" are cut next using the other edge of the
template and a straight router bit The depth of cut is equal
to the thickness of the "pin pieces" Adjustments are made
at this point to oblain joint fit
