Well, after 20 minutes of trying to make that turn (and about a thousand variations on "let's turn it this way" and "you turn this way and I'll turn that way") the guys decided the situation called for desperate measures. Like the kind of desperate that involves a saw.
Yep, you heard right...a saw! They sawed my desk in half! Granted I did say something like "do whatever is necessary to get this beast in the basement", but come on...saw it in half?!!
But it all worked out! The guys got it in the basement. Not in one piece, but they still made it happen. RJ put the desk back together with metal brackets and installed pieces of moulding to hide the cuts on the outside.
The most upsetting part was an "easy task" (aren't they all?) ended up taking three hours!
