For $99 there was no cast iron table and no 12" disk. It was a

You can get a 10" sanding disk for your table saw. Get the one with
one side tapered.


but don't use the tapered side to try and square up anything - the
taper will assure un-square joints.


To the contrary, the tapered side is what is meant to be used. One has to
tilt the arbor so that the taper is vertical; doing so means that the wood
can be fed into the disk without catching on the edge of the plate.
Additionally, the taper provides only one point of contact for the wood
which means all sanding will be linear and parallel to the direction of
feed rather than circular.


If you use the tapered side with the arbor tilted you end up with a "Hollow
Ground" surface.


Undercutting isn't necessarily a bad thing, such as when
you're trimming an old out-of flat window case.
