Essentially a double ended motor, with a mounting base, the motor

flanges mount the wheel guard at the dry stone end and the transition

gearbox at the wet stone end. The motor base contains the On/Off NVR

switch.

A formed metal guard that encloses the grinding wheel. It is formed in

three parts. The inner part is mounted onto the motor flange, The stone

cover is 'sprung' into the lip of the inner part and the outer part is

located on it. The whole assembly is bolted together. There are various

'hard point locations' that accept the fixing bolts that secure the

attachments of the machine.

Formed metal plate that bolts onto a hard point on the inside cover of

the wheel guard. There is an elongated slot in the rest which gives

adjustment along the coach bolt fixing.

Clear protective shield that mounts over the grindstone to afford a

view of the workpiece, but offer protection for the eyes; it is mounted

onto the spark guard making a complete assembly that bolts through a

hard point on the upper part of the stone cover. The spark guard itself

has an elongated slot to allow positioning and adjustment as the wheel

diameter decreases. Its' function is to contain any material (esp.sparks)

that would be tracked around the grindstone and sprayed out of the

machine esp. over the hands.

A transition (through 90˚) gearbox that is mounted onto the end flange

of the motor. The gearbox reduces the speed of the wet stone to approx.

120 rpm.

A moulded plastic trough that is screwed to the o/p face of the gearbox.

During operation the trough is filled with water, and the stone runs

partially immersed., This self dousing action maintains the 'cold

temperature' of the stone and helps to remove the grinding waste from

the face of the stone. There are a number of preformed notches in the

lip of the trough that can be used to rest/steady objects being offered

up to the stone. (See page 11) There is a shaped rubber plug, which

also acts as a stabilising support for the grinder as well as blocking the

drain hole. (See fig 3)

A NVR double button switch panel, marked 'I' for On and 'O' for Off. The

NVR function ensures the machine will not be left in the 'ON' condition,

in the event of a power failure, and subsequent re-establishment of the

supply.

enable the grinder to be bolted down to the bench or a stand.
