Description: |
| Lumber tester that compares the width of a piece of lumber after drying. Practability seem limited and would require a different scale for each species as well as a specific width of lumber must be used to remain within the limits of the scale adjustment.
Note that commercially dry was 3 to 5% and cabinet dry is 2% to 3%. |
