I am building some bat houses, and they need rough wood so the bats can hold

I just resawed my timber on a Woodmizer with a damaged blade on it
(around 100 bat boxes)

For making one-offs, I'd use the corner of a rebate plane held at an
angle, or a wooden beading plane I hadn't yet got round to tuning up.
Bats aren't fussy and I could do this quicker than changing blades. A
couple of strokes will put a bat-claw sized groove into soft larch or
cedar.
