RKS Arkadia Surface Grinder
Little-known and seldom encountered, the RKS Arkadia hand-operated surface grinder appears to have been built by the RKS Precision Engineering Works in Croydon, to the south of London. Looking somewhat similar to the Mk.2 Eagle, the RKS had a table 18" x 6.5" with a longitudinal travel of 14.5 inches and in traverse of 6.3 inches.
The hand-operated surface grinder market was a rather crowded one in the UK with competitors including the very similar Capco, Superior and Herbert.
For the smaller workshop a hand-operated surface grinder can prove a useful investment. They take up little room and are both cheap to operate and maintain - their being little to go wrong (apart from the main spindle) that cannot be fixed by any owner with reasonable mechanical skills..
