Newbie to the site, not a newbie to woodworking. Any help appreciated. I cannot get A straight cut when I resaw. I'm a luthier, so I need to be able to cut very straight resaw from stock, like .120" pieces. It has worked before, but not now. I'm pulling my hair and breaking everything in my shop. I have done these things:

1. Almost brand new blade, 1/2" 3-4 tpi combo.
2. Table is square to side of blade.
3. Table is square to the back of the blade.
4. Rip fence is square to the table.
5. The piece I'm feeding into the blade is trued.
6. Tension is set pretty strongly.
7. As Alex Snodgrass would be proud, the deepest part of the gullet is in the center (on the crown) of the wheel.
8. I have adjusted the fence for blade drift, checked it twice.
9. The Rikon 14" Deluxe owners manual gives no instruction on how to set bottom wheel coplanar with top. In fact, it sets a good 3/8" back in relation to the top. After research, I ruled that out as the cause because when I see that the blade tracks the same on both wheels.
10. The blade rips a piece straight as an arrow, but trying to resaw ANY sort of wood (hard or soft) the blade starts to drift immediately upon contacting the wood.
