Re: Countersinking with hand drill?
By "hand drill" do you mean electric, or the old crank style?
I've used an electric drill many times to countersink holes. Just hold it steady and straight and make sure the countersink matches the angle of the fastener you're using. There are different angles.
A drill press makes it easier but with a little care a 'hand drill' works just fine.
