Tool of the day

While we are talking about measuring tools how many folks know what this is called and used for, or has anyone used one?

It's a log scale but I don't know which one. I've never used one, any log here goes to our mill and then I know how many board feet I got out of it. International is supposed to be the most realistic scale from what I have been told, Doyle and Scribner both short the footage of small logs to compensate for the extra labor required.

It appears to be a log scale but it is unusual. The scales I'm familiar with are somewhat flexible and have a hook on one end. As for Doyle vs. Scribner, I'm pretty sure I've got this right: The Doyle scale gives better estimations for hardwood logs without much taper and the Scribner scale is for long tapered softwoods. It could be the other way around! The International scale more or less splits the difference. I've got a variation on the log scale called a board scale. It's used to estimate the bf of rick-sawn planks.
 
You are correct it is a log scale stick and it is international scale. I used it once and it was pretty accurate.
 
markct; Why do you say that? I was born and raised in the Pacific NW, and when I heard stories of people being hit with a ruler back in their school days, I always thought they were referring to other parts of the country. I'm not claiming it didn't happen here. Just because I didn't know about something doesn't necessarily mean anything. It's just that I hadn't heard about it myself, or heard that this part of the country was known for that.

The Doyle is used for the more valuable or higher grade logs. If you would scale a log less then 6 inches in diameter with the Doyle scale the scale would read nothing because the center is not measured. Larger logs will scale more with the Doyle than with the International.
 
I'll wade in here and guess that markct identified the scale as a Scribner. Scribner was the type of scale used in the Pacific NW.
 
ones with the hook are lumber scaling sticks. Tell how many board feet are in a board. The lumber grader man will use the hook to flip the board over to check for defects that will lower the grade of a board. Different from log scaling sticks which tell the number of board feet in a log.
 
Okay, that makes sense. But it's kind of like when one astrophysicist tells another astrophysicist an astrophysics joke---most people aren't going to get it.

Thanks for the explanation.

It took a while but that name finally jogged my memory. It is a Biltmore, used to scale standing trees. The other types of scales mentioned are used for scaling logs or planks.
 
What I called a hook is really just a brass flange or lip that runs all the way around one end of the stick. It's used like the lip on the end of a tape measure, just to hold the end of the scale to the edge of a plank. The flange runs all the way around the end of the stick because the stick reads on both sides. The flange is just over 1/4 inch high. Neither the stick or flange are stout enough to use for handling planks. A pickeroon was used for that job.
 
This type of stick has an interesting history. In the 1890's, George Vanderbilt hired Gifford Pinchot (future and first head of the U.S. Forest Service) and Carl Schenck to manage the forested land on his 125,000 acre Biltmore estate near Asheville, N.C. Schenck developed the stick to save time evaluating the standing timber and named it after the estate. The stick is a type of hypsometer or height-meter and uses trigonometry/triangulation to estimate height, diameter and volume without taking time to physically measure a tree.
