BTW these grooves need to be slightly rough. While I want to avoid
splinters extremely smooth groves are not what I need or want. Nor do I
want any radius at the top or bottom of the grooves. This would defeat
the whole purpose of having grooves for the bats little toenails to
grip

Why not staple galvanized 1/2" grid wire to the boards?

Wire will hurt the beasties' toesies. Use fiberglass or plastic screen
only.
