A jig to help with calibrating your laser collimator.

Set your collimator into the jig and pointed at a wall. With a piece of paper taped to the wall mark where the red laser is displayed. While  applying slight pressure to the base of the jig, slowly rotate the collimator. The laser should stay relatively centered to the mark on the piece of paper if properly calibrated. If the laser rotates around the mark on the paper adjust the calibration screws on the collimator until there is no or very minimal rotation of the laser on the paper.
