Nice informative post Jim, thanks.
I understand to goal of finding the the timber inside the sap ring. But if you are looking at long stock say 36' and you need 14 of them. Are you going to look for sap free timber? The majority of the timber will be but what is the acceptable amount of sap wood allowable?
There are many old frames out there with sap wood in the timber. Truly, how big of an issue is the sap wood?
By having to use sap free timber one is not using the timber stand to its fullest potential. The forth D can add a lot of volume to your stand, you have improved
the stand and gained by using the thinings for some of your timber needs.
