Nice attitude. This is supposed to be a friendly forum.
Is there any way to measure the distance between the two beams at known points? In other words, measure the width between the two beams at 5 feet and again at 10 feet, then figure the difference between the width of the beams. Seems easier than measuring at the convergence point.
Note: I am making a suggestion that is meant to be helpful. Masster, if you cannot handle others' opinions, suggestions, and-- God forbid-- even mistakes, then you should not be here.
