What do you mean "separate vias" ?

>> or steel as an anvil
can you expand a bit here ? I assume the piece of steel is flat, and
you place your PCB with
the eyelet in place on top of it.
Then you use the hammer to form the other side of the eyelet ? Do you
use any other tool along with
the hammer to punch on the eyelet and form it ? or just the hammer is enough ?
What specific hammer do you use ( how small ). I am interested.
You don't happen to have any photos do you ?
Thanks
