Is there an easy way to square a plywood panel or "trapezoid" piece of lumber using the 3-4-5 method? I thought i could simply draw two lines, measure using the 3-4-5 method (or construction master calculator using rise/run/ diagonal) I squared up several cutting boards today and a couple were quite painful... meaning i would be off by 1/16 on one end... I finally got there, but it took me awhile!
Where/how do i start when trying to do this when i don't have a factory edge?
Take a look at the example below. not a square corner on it...
TOP WIDTH is 15 5/8 "
Bottom Width is 16 1/2 "
Left hand Height is 10 1/8
Right hand Height is 10 1/2
How would you go about making this square?
