To process spherical or ellipse of the workpiece in the vise — not an easy task: the one who tried to hold them, knows how hard it is to do it without assistive devices. I use in these cases, the most simple: metallicheskie bottle caps, nuts, washers, depending on the shape and size of workpieces. How to use these handy tools is evident from the drawings. To avoid scratching of the workpiece, if they are made of plastic, use plastic spacers; if the metal — pick up “bagels” from a softer metal.
