I don't have any pictures, but it is refered to as line boring. You might find something.
Buy a chuck that is mounted on a taper that matches your lathe. Most of the mini lathes have a #1 MT (Morse Taper) the full sized wood lathes usually have #2 MT and metal working lathes can go up from there.
Slip has the technique down. I usually drill both ends with a short bit and go back and connect them with a long bit.
