The patented ONEWAY banjo is designed to solve problems associated with traditional cam-lock tool rest bases. The sliding cam clamping mechanism ensures tight clamping and smooth operation over the range of the tool rest base as it slides across the lathe bed.  Conventional long cam shafts suffer from cam shaft deflection when clamping pressure is applied in the middle of the shaft (the center of the banjo).  This causes non-uniform clamping over the range of the toolrest base. Cam shaft deflection also causes the clamp handle to tighten in different positions.  Oneway has solved this problem by replacing the regular long cam shaft with a sliding cam assembly.

Furthermore, the toolrest is clamped in the toolrest base with a captured non-marking block.  As a result a very tight fitting hole can be bored. This improves the toolrest clamp position. The clamp screw handle may be adjusted at 45° rotations to assure minimum interference with the handle when turning.

Dimensions of the banjo are 8 3/4" high by 18" long.
