  I don't think will work, they're tapered not straight. It will make the
tape run on the one side. I would rubber drive wheels out of an old tape
drive or the rollers out of an old printer (or copier). Printer rollers
would be too wide and would have to be cut down. The metal shaft goes all
the way through so you could cut it shorter and then trim the rubber back
to expose the shaft.
