Here is another technique that I did when I started.

I took a DIP socket and with a small drill, 25 thou or whatever you
have, drill out all the pins. this lines up the drill with the
proper holes.

Then drill the #1 hole on the DIP on your board.
place a pin of the same diameter as the drill into the #1 pin of the
DIP socket and then line up the opposite hole, the #8 on a 14 pin DIP
and drill thru the DIP socket into the board, using the DIP socket as
the guide.

Put a pin in that hole and then the rest are easy and aligned
properly.

This will eventually wear out the DIP socket and you'll need to make
a new one. But, you do get past the horror of mis-dilling a hole on
a 28 pin DIP board.

Also, if you did leave a hole in the pad, the first holes are good.
and if you mess up the first hole you have 3 other corners to use to
get it right. : )
