Sphere Turning Jig
This sphere cutting jig developed by Heinz Risse, who had been our regular demonstrator for years during the demonstration weekend, has important advantages over the conventional systems. The cutting element is in fact a kind of gouge that is placed under a certain angle in the chisel support. The main advantage of this is that the wood fibres are better cut and that almost the entire surface of the work piece can be reached. The maximum diameter of the balls is 250 mm.
The "Heinz Risse sphere cutting jig " is provided with a gouge shaped blade.
A cutter for smaller spheres (DB1242) and a round cutter with support (STH1240) are available as an option (see photographs).
