It is not a standard finished commodity lumber size. Most likely the member you are looking at is a 2x8, which measures 1-1/2" x 7-1/4".
2x7
2x7=14double = 4x7= 28
The LCM (Least Common Multiple) of 2x7 and 4x9 is 36x63.

You can not do that. You have to make lumber yourself.
Make a lumber mill My name Robertmao
2x7 = 14 x7 = 7 3x7 = 3*7 = 21
5x2=10 2x7=14 10+14=24

Lumber cars are often empty because the lumber is loaded on at the lumber mills and shipped to distributors. There is no return of lumber to the lumber mills so the cars have to be returned empty so they can be reloaded and make the run back to the distributor.
