I actually use the drill press all the time to tap holes.... just not under power. One of the big keys to tapping correctly is to make sure you are tapping it "straight" in to the hole drilled.
What better way than to just leave it in place and chuck up the tap and turn the chuck by hand? Since everything is still set up you know the quill travel is still exactly in line with the hole.
Although that does require that the part be well clamped when drilling so it doesn't move around during/sfter the drilling and chucking up the tap. (Which is the right way to do it anyway... althoughI have done my share of just throw it on there and hold it drilling too,)
It's a tip that has served me well.. picked it up on a machining forum.
It might be overcomplicating things for a newbie guide though.
