Knot Clusters and Grading of Timbers

kettleviewtimber · August 28, 2007, 12:06:35 PM

Below are 3 examples of knot clusters in Timbers that I had received from my sawyer. The timbers are 8" x 10" x 20' northern white pine. These timbers are to be used as rafters and collar ties The cut list specified #2 or better and small to medium knots. This was the second shipment from this sawyer the first was much better very small knots no wane, straight grain. This batch?

Any suggestions?

If they don't meet the grade rule you have specified then the mill/sawyer should do something about it.
If he won't replace them, then they should be discounted or something...
You could ask him to show you how these knots pass for grade #2 or better.....

On another note....
Are you familiar with the grade rules?
Are you sure these knots do not pass?

I'd have to look up the rules to be sure, myself......

I would not have taken them off his truck/or out of his yard. Those beams are not structural nor are they attractive. My suggestion would be to return the beams and talk with the sawyer about your need fo quality and what size and condition of knot is acceptable. Most sawyers are more than happy to accomidate .
