Doyle, Scribner, International

[POSTON WIDEHEAD]

Everyone where I live uses the International Rule. When do you use the Doyle or the Scribner?

I had a customer who wanted his lumber sawed using the Doyle. I told him I used the International Rule. He got a little upset and I told him he could take it some where else.

He had 4 Loblolly pines 24d x 12L.

I was just wondering when and if the other rules are used?

Thanks, David

Everyone I know around here uses Doyle.  Can't tell you why.  Just the way it's always been.

Doyle = 300
International = 320
Scribner = 300
X4

Don't think the sawing of the log has anything to do with the scale/rule used to estimate the volume in the log in bdft.
That scale/rule is an estimate to buy/sell/trade logs (like a dozen eggs or a quart of milk) albeit not as precise.

Could easily scale the customers logs either way, and would have nothing to do with the charge per bdft actually sawed out of the logs. Only if the customer said he would pay for the sawing based on the estimate from the Doyle rule, would it have any effect compared to using the Int'l rule.  IMO

The Int'l rule is a more accurate estimate of the yield in bdft of a log. The Doyle rule is used by mills to purchase logs because it underestimates the yield in bdft for smaller logs. Arguments that say either rule is okay as the log price per bdft of a log gets adjusted up or down by the buyer/seller agreement.

I gotta wonder along with beenthere.  Log rules are for estimating the footage in the log, not for measuring the volume of lumber cut on the mill.
