Like many turners, I use adjustable, flat-plate “Jumbo Jaws” to hold a bowl inverted for the final turning of its foot. However, I find that if the rim of a bowl tapers inward, the grip of the rubber buttons against the work can be compromised. My solution is to mount the buttons on “standoffs” I make from 5⁄8"-dia. dowel rod. The increased reach makes all the difference.
The standoffs can be made to any suitable length, and bored through their axis using a drill chuck on the lathe. For stability, make sure the ends are cut perfectly perpendicular to the length of the dowel. Replace the stock button machine screws with longer versions from the hardware store.
