I have an older Rockwell/Delta 1" x42" belt grinder and sander. The
1/8" rubber that was on the 3.5" diameter plastic drive wheel has
rotted away leaving only the wheel. I'd like to replace it with
another rubber, but I have been unable to locate a suitable
replacement. A 3" diameter inner tube might work, but what kind of
adhesive should I use? I have some cork and rubber gasket material
that I could cut and place, but it would have a seam. The drive wheel
does not come in contact with the work, so the seam may not matter. I
don't want to botch up the wheel, so I need some advice. TIA

As one poster suggested try running with the bare drive wheel.

I tried this and when attempting a "heavy" grind the belt would
slip.

As a quick fix (about 4 years ago) I wound on a layer of black
rubber "insulation tape" (not the cloth or plastic kind). Make
sure to wind in the same direction that the belt will turn so as
to avoid having the belt try to unwrap the tape. Overlap the
tape about 1/2 the width, and you may want to build up the center
to provide additional crown if you are having problems with belt
tracking or the tendency to work to one side or the other off the
pulley.

This worked so well that I now consider this a permanent fix, and
the tape is still slightly soft.

George:
I have some of this tape. I think. There is little or no adhesive on
the tape...correct? I use it for wrapping a split bolt wire splices.
More rubber than tape. Same stuff?

============
If it sticks to itself, yes.

When you get enough wrapped on the roller pull the tape apart and
it will stretch and thin when it tears. This will make a flatter
joint and eliminate a possible "thump" with a square cut end.

Good luck and let us know how you make out.

Well, I stripped the old rubber tire off the wheel, and ran a belt
with the drive wheel naked. This seems to work. I will run it like
this until the wheel wears out or slips. When and if this no longer
works, I will try the rubber tape or just make a new drive wheel.
Thanks everyone for your suggestions.
