Answer :
The distance between the work rest and the grinder wheel should not exceed a certain limit in order to prevent jamming. This is because when the distance is too large, it can lead to instability and increase the risk of the workpiece getting caught or stuck in the grinder wheel.
To determine the maximum allowable distance, it is important to consider the specific grinder being used, as different grinders may have different specifications and safety guidelines. Generally, the manufacturer of the grinder will provide recommendations on the maximum distance between the work rest and grinder wheel.
For example, let's say you are using a bench grinder. The manufacturer's guidelines may specify that the distance between the work rest and grinder wheel should not exceed a certain measurement, such as 1/8 inch (or approximately 3.2 millimeters). This means that the work rest should be positioned close enough to the grinder wheel, ensuring that there is minimal space for the workpiece to become wedged or jammed.
