Title: scaling logs
Post by: Dave989 on February 04, 2016, 08:20:04 PM
I live in central Wisconsin and I am starting to buy logs an sell lumber. I am wondering what scale most sawmills use in this general area. Scribner? Doyle? International? Also are their any books or online courses that will teach me more about scaling logs? Do sawmills scale the logs and tell the logger what they will pay or is it the other way around?

i dont know what scale is used up there ??? here it is doyle. but i will say scale the logs right and thats final if loggers argue about the price is fine but if they argue about footage take the stick and scale the with him watching that should settle any dispute and i dont saw logs i buy until he is payed or at least has a load ticket telling both footage and dollar amount then if he is not happy he can come get them ;D

yep, what he said, whatever the common scale is then go by that.  inside bark no heavy thumb, logs are what the are, give the advantage to the logger,  the only rule of thumb I know, sleep well at night.  On in between numbers it most often goes give and take, one side goes to you the other the logger,, best to call it close, I like the International  makes more money for the logger and you should make out with a band mill, if that's what you have,, sweepy logs and degraded ones are a different ball game, not really wanting to go there,

In WI, pretty safe bet it is Int'l scale.
But if you can buy logs on Doyle scale, then it favors the buyer on small diam. logs (under estimates volume yield).

Int'l will come the closest to estimating the actual volume yield if you don't cut thick slabs.

Scribner is used in the West, and some in the NE US. 

Here is a document on more than you ever want to know about different log scales and the history of their making.

In your area the mills primarily use the Scribner Decimal C log rule.  Likewise, on all Wisconsin DNR contracted lands the Scribner Decimal C log rule is required.  Mills do their own scaling but even more important than scaling is knowing your grades when buying or selling logs.

    I don't buy logs so doesn't affect me. I have an Int'l Log Rule printed on the back of my business card for customer convenience.

   Whichever scale you land on just be clear to your provider. You might keep handy sheets printed or on line for your suppliers to see and use.

 have found a couple of guides on the internet for free on this subject. The first is from the University of Tennessee Extension Service and is titled "A Hardwood Log Grading Handbook" and the second is from the USFS and is titled "A Guide to Hardwood Log Grading. Second book also says technical report NE 1.

I downloaded both in PDF form.
