A shorter course in woodworking; a practical manual for home and school . Fig. 639. Fig. 637 Fig. 640 The bottom is often fitted between the sides and ends, so as not to show;but as it afterwards swells, or shrinks, or both, it may either open a crack atthe side or perhaps force the joint apart (Fig. 638). A better way for nicework is to fit the bottom into a rabbet (page 159), cut in the lower edge ofthe sides and ends (Fig. 639 showing box bottom up). Thus the bottomcan be loose enough to allow for expansion and contraction. The lid orcover can be hinged to the top edge of the back of the box or arranged as in Appendix 239 Fig. 640. Plain lids, for everything but rough or temporary work, shouldbe strengthened either by cleats at the ends (page 157), by cleats on theunder side (page 157), or by framing (page 167). Box joints are sometimes mitred (page 142). It is, however, a poor wayin point of strength and only a skilful mechanic can make a box with nicelyfitted mitred joints that will hold permanently. Mitred joints can, however,be strengthened by splines or keysâ
