 americancanuck416 posts in 2689 days 01-03-2018 02:11 PM In a recent search for some rough 8/4 fir I was told that the price was \$6.89/board foot and that the price for 4/4 was \$5.50/bf. This did not make sense to me. Can anyone explain to me why this would be. -- Retired and lovin it

Harder to get 2” thick boards in a given grade than 1”. There are also volume effects; most sales are 4/4. mpounders: he is quoting board feet, which takes into account thickness. A 12×12 x 1 board is one board foot. A 12×12 x 2 board is 2 board feet. If the price per board foot was constant, the 12×12 x 2 would cost twice as much as the 12×12 x 1, but as the OP says, he is being charged 6.89 per BF for 8/4 and 5.50 for 4/4. So his cost of a 12×12 x 1 is \$5.50, but a 12×12 x 2 board would cost him \$13.78 and not \$11 pmayer1028 posts in 3145 days #5 posted 01-03-2018 02:40 PM I’ve always figured it was because of what brtech said plus longer drying time. My lumber guy charges the same regardless of thickness, but that is unusual. I’m also buying green so there is no drying time difference for him. There is for me, though. :) -- PaulMayer, http://www.vernswoodgoods.com rwe21563033 posts in 1560 days #6 posted 01-03-2018 02:48 PM I think its a combination of longer drying time, fewer boards in kiln, demand. -- Everything is a prototype thats why its one of a kind!!

The longer drying time is of course a factor to. draw a circle and then draw a square in the center away from the sapwood, all that side lumber will be 1 inch.of varing widths It is also a cheaper grade. I wanted some good black walnut at a local store, and most of it was just junk, from side lumber, knot and part sap wood. They buy it as it is cost effective I quess.

It is NOT ALWAYS the case. Sometime 8/4 is LESS expensive.Don’t forget market forces in play (Supply vs Demand). This can affect prices as much as any other factor. -- "Hard work is not defined by the difficulty of the task as much as a person's desire to perform it.", DS251 splintergroup2201 posts in 1302 days #13 posted 01-03-2018 04:09 PM I see the same thing here for white oak.

It also means that because it’s one, 8/4 board that the associated costs to mill it are higher, thus the higher price, and that just because you think it should be cheaper that it doesn’t mean that it’s going to be. FYI you totally missed the diamond comparison. Gilley23489 posts in 462 days #15 posted 01-03-2018 04:32 PM Double post.
