Cracked Lid

All that I have seen have been edge glued. A good edge-glued joint should be
(and is) stronger than the wood itself - so there is really no reason to
ever see the joints. When I clean up my shop floor of wood cuttings around
the bandsaw, I routinely grab a few several-foot-long cuttings from the edge
of a spruce soundboard panel(s) (comprised of several/numerous edge-glued
flitches) and give it a whack on a table edge to make it smaller for the
trash can. I enjoy inspecting the breaks - I have never seen one break at
the joint - always breaks somewhere in the solid wood.
