How Yellowhammer Sees and Saws Stuff

[Larry]

Walnut rules were made by the "Walnut Baron's" years ago.  Application seems most relevant when the lumber is steamed and sold on the wholesale market to manufactures. 

In today's retail trade, I don't think any of the grading rules make sense to the average woodworker.  Most only see lumber as good or junk.

One trick some are doing is selling FAS1F.  To get those boards their robbing the 1C grade.  Customer is basically paying FAS prices for 1C lumber.

YH, your on to something with the HHA high grade stuff.  Good on you!

In the foreword of the NHLA rule book, it states "hardwood board is graded on its useable content.." so is meant for further cut-up (manufacturing) and not used as a whole board like softwood and the softwood grades (in general). Helps explain the sizes, the cutting sizes and percentages of cuttings of those certain sizes. 
Suspect it is also for the members of the NHLA to know what to expect from a grade when buying and selling. 
Don't know of any restriction that the buyer and seller can't agree on their own rules, i.e. clear both faces, no sapwood, etc. etc.

I have seen hardwood lumber graded Select and Better. was told it's FAS 1 Face.

That is what I grew up with, Select is FAS1F, the inside of that box is lined.

And catching up, the similarities in pith and mature wood is chemical but not structural. It is built with the same stuff but quite differently.
