Well, my crappy Harbor Fright spiral sanding roll mandrel snapped while I was working. You know it's not quality when they supply you a new one with every 9-roll pack of sanding spirals, lol. At any rate, here was my solution:
1. Chuck a deck screw into my drill with the head sticking out
2. Buzz the head on my grinder down to just shy of 1/4 inch
3. Wrap some duct tape around the shank to fatten it up
4. Chuck it into my die grinder and cut it to length
Technically, I made two, and this is the shorter one; the spiral sanding roll was longer, so I didn't cut the screw as short. The idea is the same, though.

Must be even better than HF, because I spun through 3 rolls on my first TGV, and only 1 roll on the other. Some of that might be technique, but with the HF mandrel, I could see the roll wobble around as it wore out a little. With mine, little chunks just fell off the edges.
Added bonus, I cut some abrasive pad into strips and made a very archaic flapper. Here's a look at the finish I managed.
