I purchased about 150 bf of walnut from a N Caroling mill a little over a year ago. It had been kilned dried w/o steam. I stickered it and am now ready to start dimensioning the lumber. I know the typical process is to first joint the flat side in prep of planing the opposite side. The boards are about 9’ x 8”-14” x 1.15”, and have some warping/cupping…at least on the top of the pile. I have a short bed 12” jointer, so should be able to handle most of the boards. However, due to them being somewhat unwieldy, would it be better to rip the boards down to within a 1/2” of the width to maybe get away from some of the cupping, and then start the face jointing? The downside I see is maybe a little more waste. The upside might be to better be able to maintain a finished 4/4 thickness that I am shooting for. Your advice would be greatly appreciated. Thanks

I would rip them down as you stated without hesitation.

Sure. Rough size, then plane/joint. Remember thet you’ll get a little movement in the wood after jointing/and planing. Let the wood “rest” for a couple weeks before final sizing.

I would definitely rip the cupped boards. You can always glue them back up together and you will not be able to tell that they were ripped as the grain will match and the board will be much more stable and your finished thickness yield will be significantly higher.

Rip to size in a project, rip to conserve—less than 3/16, rip to high-grade or recover strong figure. Do what you like best. s
