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.

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.
Using shelving in your room or kitchen is a great way to arrange and de-clutter space… I know, such ground-breaking term it is. Do not write me off yet, I just want to show you how you can build some clean floating corner shelving that appears to have no brackets. You can create them at no cost, and the hardest part of the plan is figuring out what you are going to put on these shelves when you are finished.
Here’s a nifty tip—with a nifty tip—from faithful reader Don Ayers: Fill snap-capped sports water bottles with glue and stick them upside down in a hunk of 2×6. Now you don’t have to wait for the glue to run into the neck of the bottle, and the cap will control glue flow (and never get lost!). To holster the glue dispensers, cut holes in the base with a spade bit that’s a smidgen larger than the cap’s diameter.
