The Potter "Large Turret" attachment was 7 inches long and mounted a 9-inch long slide with 3 inches of travel and a 4-inch diameter turret with six 5/8" holes. It was designed for light production work and all its working parts were of hardened steel. The head was self -indexing, the rotation taking place at the end of the stroke and using up 1.125" inches of travel - leaving just 17/8" of sliding tool movement for machining operations.

The Lever Chuck Closer (at the time what are now called collets were known as "chucks") was supplied as an aid to production work and fastened to the end of the bed by one bolt. As a aid to efficiency the unit could be set so that the collet opened as soon as the operator released the closing pressure on the hand lever.

The Milling and "Live Spindle" Attachment required the use of the compound slide rest for its mounting - the unit was bolted into the T slot of the top slide and carried an indexing unit which accepted the same collets as used in the lathe headstock.
The unit could be used to hold, move and index any circular material against a cutter held in the lathe headstock - or, alternatively, a pulley could be substituted for the division plate and the unit used as a live spindle for high-speed drilling and grinding.

3-speed "Grinding Countershaft" for wall or ceiling mounting.
Typical of the drive units made for precision bench lathes and other small machine tools - i.e. heavy and expensive - the 32" long Potter unit has the merit of simplicity being based on two steel bars held in clamps. The final 3-step drive pulley to the lathe was on the left-hand side of the unit whilst the centre section contained three sets of fast-and-loose pulleys, each fitted with a belt-shifter crank which would have been foot operated by individual pedals..
Mounted above the main countershaft - and driven from as flat pulley on the right-hand side - was a large round-rope pulley to power grinding and drilling heads mounted in the lathe's toolpost.
A two-speed version, without the grinding pulley attachment, was also manufactured.
