The follower comprises a first portion adapted to be pivotably mounted on a follower shaft and a second portion adapted to contact a cam surface. The first and second portions form a generally V shape. The first portion includes a bottom and a pair of side walls connected to the bottom. Each of the side walls has a hole therethrough, and the holes are coaxially aligned to accept the follower shaft. The second portion includes a first end connected to the first portion and a second distal end which contacts the cam surface. Also disclosed is a method of making a follower from common sheet metal.
