The end of one member is butted against the face or edge of the other.

It is used in cabinet-making where the presence of nails would be unseemly.
[Illustration: Fig.246.

Lay-out by Thru Dowling.] In a doweled butt-joint the dowels may go clear thru the outside member, and be finished as buttons on the outside, where they show.
To lay out this joint mark near the ends of the edges of the abutting member, X, Fig.

246, center-lines A B.Draw on the other member Y, a sharp pencil-line to which when the lines AB on X are fitted, X will be in its proper place.

Carry the line around to the other side of Y and locate on it the proper centers for the dowel-holes E and F.Then fasten on the end of X a handscrew in such a way that the jaws will be flush with the end.
