Contact wheels are a must-have for hollow grinding knife blades, but they’re also fantastic for smooth, efficient grinding. This attachment is simply a fork that can hold either a 8″ or 10″ contact wheel, with an adjustable flange that allows the tracking to be adjusted independent of the main tracking on the grinder. This independent tracking adjustment is helpful to make sure the belt will always track correctly when switching between different attachments, different rotation directions or even different wheels within the attachment. The axle of the wheel is positioned in line with the axis of the grinder’s main hinge, which means the wheel tilts in place when you change the orientation of the grinder. This way the table doesn’t need to be moved at all when tilting the machine. To see it in more detail, watch the video below:
