Is my disc tapered because it was designed that way or is my disc

You bought it at Harbor Freight. You paid 80 bucks. Do you *really*
need to
ask that question? :-)

Since there certainly appears to be an "object" known as a tapered
disc, could it be that this is what comes with the HF Disc Sander or
are tapered discs only used on table saws?

Obviously that's "what comes with the HF Disc Sander" -- the question
is
whether it's intentionally so.

Seriously, though: the disc should be flat. Maybe not dead flat -- a
disk
sander is not, after all, a precision tool -- but it should *not* be
out by 1/16" across an 8" disk.

Actually there is quite a bit of information on the net about why a
sanding disk should be tapered. So far, I haven't seen anything that
really answered the OP's question, other than opinions about HF, and some
well intended guesses. The one advantage that a tapered disk holds over a
flat disk is that it allows you to feed stock in as if you were ripping
it - which you could not do with a flat disk. I'm not so sure at all that
it should not be 1/16th of an inch across its surface.

I can assure you that a bench top disk sander sands in the wrong dirrection
for feeding stock as if you were ripping it. One on a TS is a different
matter but this is a sander where you feed the stock pretty much into the
disk at a 90 degree angle. You want to use this machine for shaping curves.
or angles.
