Groove or slot milling. Groove or slot milling is an operation in which side and face milling is often preferred to end milling. Slots or grooves can be short or long, closed or open, straight or non-straight, deep or shallow, wide or narrow. Tool selection is normally determined by the width and depth of the groove and, to some extent, length.

At Gray's Mill, a Sluice Gate was used to start and stop the flow of water from the mill pond across the road. The Sluice Gate was opened by a turning Sluice Wheel, which starts the flow of water, causing the water wheel to turn, thus providing power to grind the grain. Eventually, as water levels in the mill pond became unreliable, drying ...
