Blade support device
This model is complete and sits on the SSM-2.
It is used to center the sharpening on the skate blade.
SRK uses an adjusting screw that you adjust to compensate for the width of the skate blade.
Can be mounted on old versions of SSM-2.
The Blade support device is used to get the hollowness on your skate centered by controlling the vertical position of the skate holder. When sharpening a skate hollow, put the skate blade on top of the roller.
The Height adjustment screw directs the vertical position of the blade support roller. The screw is marked with the digits 1 to 5 corresponding to about 0.2 mm movement per digit (in skate blade thickness).
By using a guide arm holding the skate blade, and a blade support roller just in front of the grinding wheel, the SSM-2 models will position a hollow very precisely using only one height adjustment point. This is so even if the blade is not completely straight (which it almost never is). No other design can match this. Furthermore there is no possibility that the hollow will be formed diagonally along the blade.
