You might want to do a little practicing first. Take a 2X4 and make a series of marks in exactly the same spot on each side. Mount the piece of wood in a vise and with an electric hand drill and a .125 drill bit, see if you can consistently hit the corresponding mark on the blind side. They say you can get close and wallow the holes out to make it align, but that just looks poor. Better to practice first. Remember, perfect practice makes perfect!
