Title:   Need Chart
Post by: dail_h on January 08, 2004, 02:15:31 PM
   Anybody got a Doyle scale chart that I could copy? I must have a dozen around here,but can't seem to be able to put my hands on one. Lengths as short as possible would be good.
   Thanks

@ dail_h

I haven't a chart but here's the formula


 Log Volume (bd. ft.) =((Diam – 4)^ 2* L
                                          16

you can get a discussion paper comparing it with other log rules here. I think its worth reading. We use the Bangor Rule or New Brunswick Log Rule here. The Bangor is best if your buying saw timber and the New Brunswick Rule is best if your a buyer  ;D

http://www.utextension.utk.edu/publications/pbfiles/Pb1650.pdf

I don't know much about this rule, but it seems it underestimates trees with small diameters < 24 inches. And most people's woods don't average that high on the woodlot. Around here 8 - 10 inches is average. But of course your probably talking about saw stock your either selecting yourself, or someone and providing you with.

@ dail_h


oops, divide everything by 16 on right hand side. You never know how html code is going to look.

especially if your a dummy like me that doesn't know what the [Preview] button is for    :D
