No, it is not an engine, but a grinder for sharpening tools and making 'special' tool shapes. Professor Chaddock from the UK designed this many years ago, keeping in mind that the average hobby machinist could not afford commercial tools like this. Castings are sold for this grinder and the home machinist can complete the tool right in his own shop. This particular Quorn was made of Aluminum by Tom Hammond, for use by Gary Martin as it is lighter and easier to carry.
