   The most common and simplest explanation is that the fence isn't parallel to the blade, I'd check that first.

   Most likely the fence is toeing away from the rear of the blade quite severely. Have you checked the alignment of the fence recently? Slainte.

   If it only happens on this walnut, it may be that it is drier on the ends than it is past the first 6". If so this would cause the ends to shrink, or pinch in as the cut starts.

   This can also happen when there is compression wood present in the stump or near large branches or leaning trunk.

   I believe your ripping reaction wood. Try ripping another species or even another piece of walnut that was aquired at a different time. I had to take back 100 bf of cherry two months ago for the same reason. A reputable dealer will replace or refund your walnut purchase.

   Dear Dave,

   Just a guess. If it is only happening on that particular piece of wood, it'd have to be the wood, every thing being OK.

   So, any chance the wood warped a little after jointed? Or it doesn't quite joint well?

   Seem to remember that happening somewhen.

   Good luck.

   Dave,

   Assuming that the adjustment of the fence has not been knocked out of adjustment (you imply it works ok for other species of wood), it sounds like you have some reaction wood with the 4/4 walnut that you are ripping. If you can, rip on the bandsaw, if you don't have a bandsaw make sure the tablesaw has a splitter installed.

   Best of luck

   The fence is parallel to the blade. I've had this problem w/ wenge as well. Both the walnut and wenge came from the same supplier, Lane Stanton and Vance. The only other wood I routinely use is cherry and maple, both with good results during ripping...

                    Dave ,

       I would guess that board you describe was banana shaped before you jointed it. Where both edges were curved in a parallel fashion. As has been posted , the cause most likely is what I learned to call timber bound or tension wood . Possibly from the growing conditions or the drying cycle .Unfortunately there is little you can do to change the condition. When I run across boards like that I try and use them as large as possible , like if you need 5 or 6" pieces for anything as opposed to ripping down to say 1 1/2 " strips.This may allow you to use the wood you have. If not than follow the advice of a previous post and if you purchased any quantity return it to the supplier. As long as you bought graded stock , you have a reasonable expectation to be able to use it.IMHO wood can be a very unforgiving medium , which can tax our ability to read the boards so to speak.

                        good luck                          dusty
