Building a workbench with some maple I got. The maple is
in shorts. They fall between 3 and 5 inches across and
are planed to an even 3/4ths thickness. Length is variable as
well.

If I build a work bench top with this wood and use
plywood as a substrate, should I be concerned with
doing something on the underside? I know it's recommended
that if you veneer a top, it's wise to do both top and bottom, but
what about thicker wood?

Thanks,

MJ
