Set the table saw fence so the blade is centered on the seam, then push the whole thing through the saw. If the board edges are quite bowed or curvy, you may need a second pass. If so, unscrew the cleats, reclamp the boards across the middle center, then screw on the cleats again. The screws ding up the ends of the boards a little, so cut the boards you’re jointing a bit long, then trim 1/2 in. from each end to remove the screw holes.

Finally, properly preparing your wood surface is super important. It will make a huge difference when it comes times to stain, paint, or finish your wood. There are a lot of tips for wood surface preparation, but sanding the wood is one of the most important steps. And I find it really helpful to do the bulk of my sanding before I start ripping (cutting) and building with my wood since it’s still in whole pieces. You can check out my simple tips for how to sand wood in my how to stain wood tutorial, which is also good to reference if you need to learn how to stain too!
Often times at first glance a board looks straight and the fact that it is actually bowed or has some warping isn’t always obvious. So the trick to knowing for sure, is to hold the board up towards your face, with the other end on the ground, and look at it at a downward angle (as shown in the below photo). This method will allow you to see if it is bowing at all.
