woodturning and metal spinning lathes do not have cross-slides, but rather have banjos, which are flat pieces that sit crosswise on the bed. the position of a banjo can be adjusted by hand; no gearing is involved. ascending vertically from the banjo is a tool-post, at the top of which is a horizontal tool-rest. in woodturning, hand tools are braced against the tool rest and levered into the workpiece. in metal spinning, the further pin ascends vertically from the tool rest and serves as a fulcrum against which tools may be levered into the workpiece.
