I've got white pine that I'm (finally) making my Dutch tool chest out of. It was dimensional 1x12 as CS talks about in his article on it. After acclimating in my shop, it got a pretty good cup in it. I started planning it down flat. It just happens that a couple of videos I've watched lately - Woodwright shop and Paul Sellers - talk about not fixing the cup and letting the joinery straighten out the piece.
Did I make a mistake in planing it down? Will it be too thin for a tool chest?
Ive got enough stock to recut the sides that I've planed no problem and I can use these pieces for drawer sides later on.
