Im fitting my tenons and trimming the shoulders for a nice tight joint. Shoulder planes are great! While dry fitting i got a nice tight joint, but is out of square to the leg. Im thinking i need to readjust shoulders so joint sits square comfortably with hand pressure. I can probably just clamp the assembly square and have a tiny gap on an nonvisible joint. BUT, ill know! so im gonna recheck all my joints for square to leg and adjust shoulders as needed.
