Diagonal bracing or strutting is nowhere to be found, and in many cases mortises and other joints are such as very materially to weaken the timbers at their points of connection.
Separate teeth, fixed into mortises in the rim of the wheel, are called cogs.
That way you don't cut mortises in the wrong edge.
Each board securely rested in two sockets of silver, having mortises into which the tenons of the boards entered.
Tenon cutters attach to the end of an electric drill and shape the ends of the logs so they fit into the holes, or mortises, of another log piece, creating a mortise and tenon joint.
