Well, just broke one of my desk legs doing the mortise. I knew when the chisel hit a little resistance it was a bad idea but pulled anyways. Broke part of the side and top of the leg off. Was pretty much that whole area there. Glued it back together and don't think it'll be a huge deal at all. Cosmetically you won't even see it b/c it'll be hidden by the apron and the top of the desk. Emotionally it just sucked, so time to take a break!
