Viceroy TDS Pedestal Grinder
IntroductionThe pedestal grinder is suitable for use with hardened metals only! The use of softer materials on it causes the wheels to become clogged which means it grinds less effectively, is more likely to grab at work and can become unbalanced and increases the risk of a wheel shattering. It also means the wheels have to be re-dressed to restore normal performance; Re-dressing is a dirty, nasty job and doing this too often shortens the life of the wheels considerably. For softer materials such as aluminium or low-carbon steels the belt-sanders or an angle grinder with a flap-disc are probably more appropriate for surface finishing or the angle grinders with a grinding disc on them will remove more material. If you're using the wheel and you start to see it getting shiny at all that's a sign a clogging, STOP!
The Right-hand wheel is a coarse grit used for crude shaping of tools, the left-hand wheel is a finer grit that can be used for putting a finer finish onto tools. For tools to use with wood or plastic then additional honing may be needed, for tools for use on harder metals then the finish provided by the fine grit wheel is likely to be sufficient. The yellow water trough at the front of the grinder can be used for cooling tools while grinding. Water must only be applied to the work-piece, NEVER directly to the wheels.

Materials that are safe for use
If you have a material that you're not sure about then you can test it with a file. Get a standard metalworking file and run it over the material with a moderate ammount of pressure, compared the results to the images below to know if the material can be safely ground on the pedestal grinder
We're soon going to be upgrading the grinder with brand-new grinding wheels including a green-stone wheel that can be used to sharpen brazed carbide tooling for the lathe and milling machine. The grinder is going to become an induction-required tool when that happens.
