I think it was Wayne from Dayton who posted about marking the floor where a laser light hits. I made a bracket to hold a laser-level on the forward side of the prop
. The bracket is made of acrylic so as not to scratch the prop
. The bracket touches the prop
at 3 points. It must be positioned exactly the same distance from the end of the prop
each time. The level comes with a built in magnet. I put another magnet into a hole in the acrylic to attract the level. And I glued a couple of cleats onto the bracket to keep the laser-level in position with no play. The prop
must be level while checking the pitch. A 1/16" difference on the floor equates to about 0.08 degree. If you can get it that close, you are doing well.
