Inspired by the router table concept, the table holds the grinder while working the wood on the tabletop which provides much better control and results. The table provides support for the workpiece while grinding and with its fence allow manipulations similar to router table functionality.
The die grinder is strapped to a vertical sliding panel which moves up and down to allow bit height adjustment and replacement:
The sliding mechanism is based on aluminum pipes running inside a round groove between the frame and the tool holder.
Here you can see the screw pole which creates the up and down sliding movement of the bit.
