$0
The double 0, the smallest in Kemper's rib range. For work where a full-size rib simply will not fit the curve.
RB00 is the double 0 rib, the small end of Kemper's rib range. A rib trues the wall and compresses the surface in the same pass, and the size decides where it can do that. The double 0 goes where the larger ribs bridge across a curve instead of sitting on it - inside a cup, a small bowl, the tight sweep near a foot. It is a specialist rather than a first rib: on anything wide you will be making many short passes and leaving the facets that come with them.
