Previous work has shown that by using round mortise and tenon joints,
durable maintenance-free school chairs and desks can be produced from
largely waste local woody materials by cottage industries in remote
regions of the world. Results of this previous work would suggest that
by using this same method of construction, well-designed, durable,
functional bookcases also could be produced from locally available
small-diameter tree species and thin plywood or other thin panel
materials. A number of panel and frame bookcases utilizing round mortise
and tenon joints were constructed to evaluate their performance. Tests
conducted on the resulting bookcase frames and shelves indicated that
shelves constructed of thin plywood supported by small front and back
shelf rails with ends joined to the corner posts with round mortise and
tenon joints easily met critical shelf deflection criteria. The
excellent deflection characteristics of the shelves were credited to the
high degree of end fixity of the shelf rails that was obtained through
the use of snug fitting round mortise and tenon joints.
