The rubber grips on my Cole Jaws were too short to use for my bangles and too short to safely retain some platters or bowls by the rim. Found a solution that did not require me to make wooden grippers.
Found single hole test-tube hard rubber stoppers, 1 inch long from a scientific supply house that do the trick. Bought some 1 1/2 inch long Hex Cap Screws, M6-1.00 x 40 (big box store) and appropriate washers that fit my Nova Cole Jaws. Since the rubber stoppers are a bit bigger in diameter, it reduces the maximum rim size you can hold in compression. Conversely, it increases the maximum diameter you can grip in expansion mode. I have no financial interest in the supplier of the stoppers but if you want address, send me an email. The stopper description is, "Stoppers #6, 1-hole" and they come 6 pieces in a bag. The center hole is the right size to fit the M6-1.00 x 40 Hex Cap Screws. See attached photos.
