I am building a 8' high by 4' wide book case. The only thing unusual about
it is that the bottom 2.5' will house a wall mounted air conditioner. I
want to build a louvered door (2.5' x 4' wide) to hide the AC.
Is there a good reference on how to build louvers? I imagine it is simply a
matter of routing diagonal slots for them, but it would be nice to learn
from someone elses mistakes...
Thanks.

Moveable louvres, Toller?
How big did you want the slats to be?
