I'm new to this group so please be patient if this has been covered.
I'm looking into purchasing a molder/planer. The biggest project is
for casing/base molding. I see rough cut lumber that is all 4/4 or
thicker. Where do I go to find 1/2 to 5/8" lumber or is most of this
cut from 4/4. Seems like a lot of waste both lumber and money.

Thanks in advance.
