I am looking at a hardwood lumber product sheet from a local lumberyard, and am wondering what the following sort of terms mean.
I understand 4/4 = 1" thick, 5/4 = 1-1/4" thick, etc., and that these are nominal dimensions for rough lumber - if it is surfaced on 2 or 4 sides (S2S, S4S) it is somewhat thinner, correct?
How about the following terms?
5/4 #1C / HoM 15/16"
8/4 S&B / Rough
4/4 S&B (90/90 Color Sort)
1x4 C & BTR
S&B means “Select and Better” i.e., I believe, a good grade of timber free of visible defects, so suitable for more decorative uses rather than just structural.
FEQ = First European Quality.
FAS = “Firsts and Seconds” - i.e. the top two grades, similar I think to S&B.
I assume RIFT and QTR refer to rift-sawn and quarter-sawn boards.
BTR just means “better”, so “C & BTR” is “Grade C and better”.
Not sure about HoM.
HoM = Hit or Miss planing, which is also abbreviated H/M
Since it is planed it will be 1/16" thinner than rough stock.
