Re: The Home Improvement Thread. Successes and Failures
A 2x4 doesn't lose that much size from the drying process alone. What you buy at Home Depot is "dimensional lumber", meaning that after it has been dried it has also been milled down to a standardized finished size with smooth surfaces. You can get rough cut lumber at a lumber yard and mill it yourself if you want. That rough cut lumber is closer to the advertised size (but not exactly)
At the Home Depot we bought all our house crap at there were signs that clearly indicated this. (It was, by the way, news* to me.) I would think the presence of signage nullifies the argument.
IINM when it says "4x4" there are no units specified, anyway, so for all one knows 4 Rigelian skulpulshanks equals 3.5 Earth inches, and the name is correct.
