The threaded collar can be wound up and down to set the drill's depth.
Edge finding from the vice jaw and parallels
Using an edge finder or wobbler, it is very easy to find the edge or centre of
a workpiece. However, you cannot always find the edge of a job, for instance
because the job is lower than the vice jaws. In this case, there are two ways
to find the edge:
One is to temporarily put the workpiece in the vice higher than normal. The
work-piece does not have to be flat in the vice; as long as it presents a flat
face to the wobbler it can even be held on an angle in the vice.
Another method is to put a parallel into the vice and use the edge finder on
that. Either method will do what we require.
