I'm hanging a new stable-type back door today. Done the hinges and fitted the
doors in the frame and now I have to fit 2 Chubb mortice deadlocks. With all
the modern machinery now available, is there a better way of forming the 75mm
deep recesses for the locks? I'm still using the old brace and bit and
finishing off with a chisel, what do you do?.
