Can anybody tell me how a 2x4 (bottom cord truss bracket or purlin)may have gotten saw cut's in it? The board was 10 ft.long and got cut to 9ft.9 inches when installed in my 24x30 ft. pole building with a 12 ft. overhead door.I've been told it probably came from the mill with the saw cuts in it.Three of the saw cut's are about 2 1/2 ft. from each other from one end to the other.The other 2 cuts are exactly 2 inches from each end and line up perfectly on the edge of the metal when put into a joist hanger.Most of the cuts are 1" deep but one that is 2 1/2 ft. from one end is about 1 1/2 inches deep and could be easily broke.If you stand the board up on it's narrowest side(1 1/2" width),you can see all the saw marks are on the same side.Also,the cuts are no less than 3/16" wide as I put 3 71/4" circle saw blades together that are 1/16th of an inch wide and set them into the cut's to measure them as well as a measuring tape.This board was placed into the joist hangers at the time the building was erected and the contractor claims it wasn't he that put the saw marks in it.When these boards are cut at the factory,are they cut where the pole building company prepares the building to ship to the contractor or from where the boards are cut and shipped to the pole building company? The board is made of Doug Fir.Any information on this subject would be greatly appreciated and I will reply to all that can help me with this matter.Thank You for your time!
