Precision Circular Grinding Attachment: this consisted of a baseplate mounted centrally on a tilting sine platform. Three speeds were available from the self-contained motor and drive assembly with the workhead accepting collets, a 3-jaw chuck or a No. 1 Morse taper centre. The maximum swing was 4.5 inches (114 mm)

"Mayform" Cylindrical Grinding Attachment. This had a 3-speed live and dead spindle workhead with spring-loaded centres and with a length capacity of 12 inches (305 mm). The workhead was able to move along the base unit with the tailstock remaining fixed--so allowing full use to be made of the machine's cross slide travel.

"Bowers" Inclinable Rotary Table. This unit was able to rotary grind wet or dry at angles from 0 to 45-degrees. The rotating magnetic chuck was driven by a sealed gearbox mounted on a sine table with a 5-inch (127 mm) sine bar setting. The gearbox was driven by a variable-speed 1-phase motor which, for increased capacity, was mounted on a moveable arm.

"Copiform" Surface/Profile Attachment. Made to fit a variety of Jones & Shipman grinders this unit adapted the host machine for accurate profile grinding. The working principle was simple but ingenious - a stylus being traversed over a template, using the cross and vertical feeds, whilst maintaining a zero setting on a large dial to which it was attached). The workpiece, set in line with the template, was passed under the grinding wheel on a reciprocating table. The grinding of vertical faces could also be accommodated by swivelled the template holder over to present them at an angle.

"Diaform" Wheel Forming Attachment. Made to fit many makes of grinder this unit was designed as a means of quickly and accurately "form dressing" (profiling) the grinding wheel. The shape was transferred pantographically from a prepared template and the wheel cut with a diamond-tipped tool. The template was made considerably oversized and the pantograph arm, manipulated by the operator, transferred the profile at a reduced ratio to the cutter. By this means both simple and complex shapes could be generated in a matter of minutes and increased accuracy obtained with the minimum of effort.

Radius/Angular Wheel Forming Attachment. An essentially simple - but beautifully-made device - designed for use on a variety of Jones and Shipman grinders and able to create angles and concave and convex radii up to I-inch (25 mm) on the grinding wheel. The pillar carrying the diamond cutter was arranged to slide horizontally on its base under the precise control of a graduated, handwheel turning a very fine-pitch screw. The pillar base was mounted on ball bearings and could be swung through 360 degrees. The height from base to diamond point was 7 13/32" (188 mm) with two alternative holes provided in which to mount the cutter. The degree-graduated swivelling base carried adjustable stops with - for obtaining extremely accurate settings - stop blocks that permitted the use of slip gauges. Supplied with the unit was an auxiliary base that allowed it to be mounted on a magnetic chuck or vice.

"Diaform" Tangent/Radius Dresser. Intended for the production of simple profiles on grinding wheels up to 10-inches in diameter this unit could be mounted on a number of Jones 7 Shipman grinders. All the operator had to do was pull the lever - this gave a smooth, single-handed action with a continuous movement that left no dwell marks in the wheel. The angle setting could be carried out in two ways: by setting stops against a graduated ring or by using slip gauges to make use of the sine bar principle. The radius setting was archived by the use of a 2-inch (51 mm) micrometer gauge.

"P.G." Projectorscope Form Grinding Inspection Attachment. Intended to simplify form grinding of regular or irregular shapes whilst allowing visual control during all stages of the grinding process - the profiles of both wheel and the workpiece being under constant optical supervision. A lighting attachment directed a parallel beam of light at the workpiece so as to create a silhouette on a 7.5-inch (190 mm) diameter screen. By this means the job could be compared exactly with a tracing or acetate drawing at a choice of either 10 or 20 times magnification.
