I got an old book press from my parents, and I use it for stamping into leathe, well, not really stamping but pressing, LOL. I do this because I don't have my shop press up and running yet, but I must say, it does the work. The pressure is great and devided all over the press, so I don't see why a bookpress couldn' be use with dies.... maybe I wrong, but I would say, try it, if you got one....
cheers,
