Very nice, MiLock. Look forward to more posts from you.
If somebody did not want to drill the face of the lock, they can lay the drill bit along the bottom so that it is just short of reaching the front of the lock, and use tape to mark the back of the lock. Then drill from the back until you reach the tape. The put the flat steel in from the back.
