AZ in Colorado Springs
I'll visit my daughter in Virginia next month, and she's asked me to install some crown molding in her townhome. I have a sample of the molding and will make backer board to go behind the molding. I'll rip some 2x4s for the backer board. I live in Colorado (dry climate) and as I mentioned, she's in Virginia (humid climate).
So, my question is whether or not I should flatten the 2x4s on the jointer prior to ripping them. That, should they be flattened at all? or should they be flattened here then taken to a more humid environment? Is this even worth worrying over?
