How to fix a broken bottom board on an upright?

[Joe And Penny Goss]

Hi Grant,
Are you sure this is worth the effort?!
My choice would be the land fill, but if the repair was disparately needed,
and the cracks were large enough, I would use "Gorilla" glue. It is thicker
than "Tight Bond" but can be applyed with a thin steel or wire. The glue
will expand into the voids and clamping is an option, The glue dries to a
sort of plastic and the excess that oozes out may be chipped off with  a
screw driver,  chisel or other sharp tool.
I believe there is a reason for the name of the glue other than it's holding
power. When you are finished, unless you use gloves, your hands will look
like a gorilla's.

wondering if I should just run a couple of timbers round the inside and
screw down into the bottom timber, and accross into the side and back. Maybe
both?
