hi, i have 2 openings to fill in that are a barrier to a pool area they are 2400x1100 and 1800x1100, what i want to do is make timber louvres to fit these openings the angle of the blades must be 60 degrees and the gaps no larger than 100mm, is there a way to cut grooves into side support timbers to accomadate the blades. many thanks
