Dear WoodenBoat, In the Wood Technology column for July/August 2014, the sentence "It is common practice to dry boards that are 8/4"or more in thickness" combines 8/4 with inch marks. I understand that 8/4 means a rough-surfaced board, while 2" is milled. They both may be exactly the same thickness; however, in use, the 8/4 would yield a thinner piece when milled. For instance, if you need a 1 "-thick board in a project, you have to purchase a 5/4 to get it, as the 4/4 will dress to less than 1". Combining 8/4 with inch marks blurs this distinction. I stand ready to be corrected if I'm wrong.
