Overhead Countershaft Drive on Unit Bench. This was a particularly well-thought-out system with as many as 24 speeds and which carried its countershaft on neat cast-iron uprights attached to the bench. The countershaft spindles ran on ball bearings, there was a built-in drive to power toolpost-mounted accessories and the speeds could be selected by either hand controls - as shown in the illustration - or foot pedals. However, despite all these conveniences, by the 1940s this type of arrangement was beginning to look distinctly old-fashioned .
