Advise on cutting pine

[Mhaaland]

I am looking to make some board & batton, carsiding or whatever you want to call it.
I'm looking to make 3/4" thick by 6" wide planks.  My question is what dimensions should I cut it to accommodated for shrinkage, cutting tongue/groove and finish to thickness.

For a 3/4" finished thickness after properly drying and planning I saw 1" thick material.
If you are seeking a sawblade finish on the outside you might be able to saw a little thinner.

Most pine will shrink around 6% in thickness as it dries, so if you mill at 13/16" it should dry to around 3/4".
If I'm milling to run the dry boards thru a moulder for a S4S T&G product, I'll mill at 1-1/16" green. It will shrink to 1" dry and then I can plane 1/8" off per face for smoothing it up.
Sometimes I'll make an 3/4" S3S T&G product with a rough sawn show face. In this instance I will mill at 15/16" green, it will shrink to around 7/8" dry and I will only plane the back face for a consistent dimension.
