Saw with a dovetail-saw on the mortise sides of these lines, chisel out the mortises and fit the parts together.

When glued together, the joints should be dressed off.
Where there are several parts to be made alike, it is necessary to lay out the dovetails on only one X member.

This may be used as a templet for laying out the others and they can then be sawn separately.

Or all the X members may be clamped carefully together, with one X already laid out, rights and lefts in pairs, and edges and ends flush, the depth mark gaged all around, and then all sawn at once.
The dovetail joint is also made by first laying out and cutting the members having the pins, and then superposing this on the piece to be dovetailed, and scribing around the pins.
_No.49.A lap or half blind dovetail_, Fig.

267, is a dovetail joint in which the tails on one member do not extend entirely thru the thickness of the other member.
