it would be a lot easier to resaw short pieces of the Ipe board instead of
the full 8 ft.
I'd cut a bit larger than the finished size of the plaque and then resaw
the short piece,and leave the rest of the 8ft. board the full thickness,for
other projects.
you could also use a 10" tablesaw and ripcut each edge of the [short]piece
and then use a handsaw to cut any remaining material joining them.
They would still need planing,and the tablesaw kerf would eat up more
thickness.But for a 0.5" final,you probably can spare it.You just have to
have a good sharp blade,feed slowly and use the anti-kickback guard.
You could even get closer to your desired 0.5" thickness,and perhaps hand-
plane it smooth.
