Matt, I had a problem yesterday ripping 8/4 African Mahogany with my table saw. It’s the PM2000 5hp sp, what happened is it bogged down and I mean way down. I was using a 24t FS heavy duty rip blade square kerf. I tried another blade using a 40t atb also FS blade and still the machine bogged down. I guess my question is this common with Mahogany because of the density or ?. I bought the 5hp so that I wouldn’t have this problem. thanks Ziggy

This sounds a lot like your rip fence got bumped out of alignment. I have had this happen before, where even a beisemeyer fence is aligned perfectly to the blade/miter slot one day, and then you go to rip the next day, and it binds up.
Make sure your rip fence is at least parallel, or preferably with about 1/64 toe-out on the back of the fence. (measured from the miter slot)
Sometimes you can have a piece of wood that even with a jointed edge, is not perfectly straight, and will bind slightly as the section that is bowed out slips behind the cutting teeth and rubs on the blade. An edge jointed board with a cup or bow on the flat side of the board can change how much wood is being fed into the blade even by 1/128 of inch or so, it could bind. You will almost certainly have burn marks when this happens. To contrast that, a perfectly straight board with a perfectly straight or toed-out rip fence will not have any burn marks at all.
