It's a very neat trick for light duty press jobs, and much easier to use than a large press when you're dealing with small parts. I have a cheap drill press ($60 from Lowe's) that I use almost exclusively as a press, and I have turned an assortment of arbors to use for different things. For example, it works great for pressing in the escutcheons in the reproduction grips I make. Just have to go careful on stubborn pins, I don't know how much pressure the table really can take and I don't want to find out either.
