It is used in plank flooring.
_No.75.A doweled joint_, Fig.

269, is made by jointing the two edges carefully, boring holes opposite each other and inserting dowel pins when the two edges are glued together.

It is used in table tops, etc.
Where the boards are thick enough to allow it, a squeezed joint is greatly strengthened by the insertion of dowels.
The essential point in inserting dowels is to have the holes for them directly opposite one another and at right angles to the surface.

The following is a convenient method where boards are to be joined edge to edge, Fig.262.Place the two boards back to back in the vise with the edges and ends flush.

Determine approximately where the dowels are to be inserted.
