For many years, I have been using a platen that I conceived & designed with the initial model being built by Rob Frink of Beaumont Metal Works. Designed for use on the KMG, or any other grinder that utilizes a 1 1/2" square tooling arm, this platen offers what I feel is the ultimate in versatility, and ease of changeover. Once you use a "Caffrey Platen" you'll wonder how you ever did without one! The mounting arrangement of a 3/4" pin and clamp/socket, which allows the platen to be turned to any of the working surfaces; Flat platen, 1 1/2" contact wheel, slack belt, 3" contact wheel, or any place in between, simply by loosening one hand bolt (no tools required) , moving the platen to the desire position, and then re-tightening the hand bolt.
This platen can be used on ANY grinder, even those with odd sized tooling arms such as the 1 1/4" utilized on some machines. Beaumont/KMG offers 1 1/4" tooling arms as an option when you purchase a Caffrey Platen.
The following video will show you all the uses for the Caffrey Platen, why it was designed/built the way it was, and how to correctly set it up for use.
