Leon, John could still be right in his assessment. The sled may be true
because the 90 degree fence (backstop or whatever his sled uses) is true
to the miter slot, but the blade isn't. Picture a blade that is off by 15
degrees. If the sled is square to the miter slot, you will still get a
square panel. I wouldn't want to be the operator in such a setup 'cause
there will be much burning and weird loud noises and such. If the blade
is not aligned to the miter slot, but the fence is, you would have no
problem when using the rip fence. (We're talking much less than the
fifteen degrees mentioned in the extreme example above.) When setting up
a table saw, you must FIRST align the blade to the miter slot THEN align
the fence to the blade.

Yeah I know perhaps I should have also included that he said "and produces
very lovely" cuts. If the sled were tracking into the side of the blade,
there would probably also have tooth marks on the pieces.
