A cheap way for anyone that already has the problem. Make a mount for one of
the small hand held lasers on the head aiming out horizontally, try for one
with the smallest spot possible at the distance you will need.
As far as convenient, drop a chalk line, and draw one or two lines, or even a
slotted piece of metal, be sure the line/slot is exactly vertical. Set the
laser so when it is mounted on the head, and turned on it bisects the
string/line, optional if the spot is too wide, use two strings/lines and aim
the spot between them. The further away within reason, the more accurate the
reset of the head after moving will be. You should be easily able to get
less than .001 inch. Do the math.
