Just got a sheet of baltic birch, had it cut up so I could get it in my car, got it home and - as I'm unloading it from my little CRV - noticed it looked a little thin. When I put a tape on it, discovered it was a full 1/16th under 3/4", right between 5/8ths and 3/4's. The lumber yard relunctly agreed to take it back (eventhough it was in 8 pieces). They said it came from their supplier that way whose on the metric system (that's what he said!). I said it wasn't sold to me as a metric measurement as the sales slip clearly says "3/4 inch baltic birch". I hope this is not the beginning of things to come, that it is an isolated incident. By the way, with an $11.97 cutting charge, tax and the wood = $104.23 (5' x5' sheet). Geese, this little hobby of mine is not for the faint of heart. End of rant.
