Title: (3) Different Scale(s) ~ Doyle, Scribner and Intl. < Why & Which One to Use ?
Post by: H60 Hawk Pilot on October 18, 2010, 03:10:10 PM
I ran this Log through the different Scales (listed ^ above).

Log is 14.5 inches at the small end and 12 Ft. long.

Doyle =       83 b f
Scribner = 100  b f
Intl.        = 110 b f

I'm thinking that the Doyle Scale is used to purchase logs and a little on the low side but work's better for all grades
of wood, bowed, etc. .

I tried the Scribner last night and was real close to the 100 B F. I graphed the 14.5  inch log on graph paper and got 98 board feet. I took in account for 3/16" blade cuts and it all worked out on graph paper.

Also, this was a perfect log...  straight & good wood and all that.

My Question:

Use Doyle to buy wood, Use Scribner/ International Scale to scale nice logs for (expected) B F and make No mistake's when cutting ?

You figured that out pretty well.  8)

Keep in mind, that all the scales allow for deductions for sweep, crook, rot, checks, etc that limit the lumber produced from a log.

Some parts of the country will set one as a standard measure. Here it's Scribner Decimal C. Other places it's Doyle but that is best used for buying, not selling as you figured.
