This modified version of the well-known Colyer/Caseley tool and cutter grinder was shown by Dave Arnold at the 2015 Midlands Exhibition. Several modifications have produced good results.

  1. The bearing arm and its slot have been lengthened to accommodate an ER32 chuck and to allow four-facet drill grinding.

  2. The column base slide has been lengthened to accommodate a swing stop to the right.

  3. A quick change wheel mounting system is used - similar to the Kennet design.

Drawings etc for the Collyer/Caseley are available from the Bristol SMEE.
