Finding Neo-Angles Without A Geometry Lesson

Figuring out odd return angle cuts for headers and thresholds can be done using a protractor or angle finder to determine degree of cut, but sometimes these tools are not available on the job site. So, if you need to determine these and don't have time for a geometry refresher, these cuts can be accomplished using the following procedure.

STEP 1: Mark the center line with a pencil

STEP 2: Align a sheet of paper along one line

STEP 3: Fold the edge of the paper back to form the neo angle

STEP 4: Fold the result in two to split the neo angle in half

STEP 5: Place the flat edge of paper against a chop saw rip fence and bring the blade to the angle formed by the sheet of paper

STEP 6: Cut threshold or header

STEP 7: Flip folded paper over and place against the opposite side of the chop saw rip fence and bring the blade over to the angle formed by the sheet of paper

STEP 8: Cut adjacent threshold or header

STEP 9: Fabricate the angle with supplied brackets and proceed with installation
