Even if you stack two pieces and cut them on a vertical bandsaw that doesn't mean the cuts are actually straight. Anyone who is cutting any quantities greater than 2-3 of barstock or tube to go into a mill or lathe would be much better off with a horizontal from a cut quality, squareness, and time standpoint.

I'm referring to a 3 jaw self centering chuck. If you are only clamping onto say 1/4" of length on the part you can easily end up with the part skewed in the jaws. You need to be clamping onto substantially more to guarantee that the stock is coaxial to the jaws (at least without tapping it into alignment).
