138 Designing and making shelving arrangements
used – a good visual effect can be achieved by bridle-
jointing a quadrant- shaped diagonal to each upright,
as at (g). Again, only two fixed dowel- rungs per frame
are required.
Shelf details
Figures 7.3(h)(i)(j)(k)(l)(m): As previously men-
tioned, if the end- frames are not fixed to return
walls, more connectivity has to be created between
the frames and the shelves. As illustrated below at
(h) to (k), this is achieved by gluing and pinning
(or screwing) shelf- thickness fillets to the end- and
rear- edges of the shelves. Note that the bottom shelf
requires extra notched recesses, as at (j), if the stepped
framing at 7.3(d) is used. All notched recesses should
be 0.5 to 1mm wider than the 20mm wide frame
uprights to allow easy positioning and – if required –
repositioning of shelves.

ladder- frame upright and a brass picture/mirror plate

upright are recommended.Figure 7.4 (a) Part of a newly built bookcase.
