   A wild guess here, but it sounds like your fence may be microscopically out of parallel with the blade.  The other possibility would be feed technique, but seems like you'd know about that via some kind of excitement during the cut.

   I agree with Jamie that you should check the fence alignment. Many people toe-out their fences for ripping but dado cuts are best done with the fence dead parallel to the blades. If the pitch is building up on the fence side the fence is likely toed-in.

      Hi Charles,    What is the benefit of FTG on a ripping blade over ATB, and what is Freud,s best ripping blade for thick hardwoods? TK and FK.

            I already have the 30T GLR, good blade.

                   Thanks.                                            Walker1

   Walker1,I apologize to the OP for hijacking his thread but a flat grind works like a chisel to scoop away the long grain of the wood. An ATB is sometimes used but the sharper points can have a tendancy to leave more tooth marks. Sometimes this is overcome by reducing the amount of the side clearance so the teeth burnish over the marks as you cut. A flat grind also has less tendancy to wander in stronger grained woods so it runs truer. Triple Chip grind is also used in rip blades and the effects are similar to the flat grind.When you refer to thick hardwoods I think of 8/4 material and over. If that is the case I would recommend the LM71M series. The 10" version (LM71M010) is flat grind with 18 teeth and is ideal for 1-1/2" to 3-1/2". It will also rip thinner stock but the surface will not be as smooth as an edge from a 24 tooth (or higher) rip blade.

   I saw you advertisement for the Box jointer Cutter set in the current Fine Woodworking..... I use routers mostly but looks like a good idea...Not that I am going to do it BUT... Can you stack two or more sets for a wider daddo..Sorry.. But I think really strange sometimes!

   Sorry again for the hijack.The SDBOX8 Box Joint Set can only be stacked with the two blades in the set. They will not stack as multiples on one arbor so you are limited to either 1/4" or 3/8" wide cuts. You could conceivably make multiple passes for wider cuts but I have not tried this.
