Rail hook for Erika85 table saw (Mafell)

The aim is to allow jigs to be easily clamped to the table saw's rails (sides, front or rear). The top of the hook is flush to the table and 4 holes with countersinks allow fixing a board used as base for a jig.
The hook is composed of two pieces, the smaller one sliding in the groove of the second one. The pieces are hold together and the hook is clamped to the table saw by means of a metric bolt (M6x60).
Use a wingnut to make tightening the clamp easy.
