MiniLathe Way Wiper. (Added May 2004) A way wiper is another quick mod once you find a bit of aluminum angle. A piece of felt is trapped under the angle, held in place with bolts in the holes intended for the traveling steady. My rubber way protector (shown flipped up in this picture) is held by the same bolts.

Introduction to Milling Tools and Their Application

Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.
