Hi everyone tonight:

While we are discussing layout techniques using rough hewn timber, and measuring poles to locate accurate locations for seatings and other types of points of interest such as exact final lengths, I always used and was taught to use the 36" Blind Man's rule. This folding wooden ruler was used to locate measurements from 0 to 36", and in many cases the main length of runs for barn braces came in at 36". In this case you could use a 36" measuring pole or the 36" Blind Man's rule whichever you preferred.

The technique that I used for layout usually involved placing a scratch awl at one point and then sliding the measuring pole against it or the Blind Man's rule which ever you preferred, and left it there until all measurements were done and checked for accuracy.
