that is pretty darn swish, that's for sure. A very handy addition without a doubt. It's on my (long) list of future projects, though most likely it'll wait until I need it for another project. I did make a mini-press brake to bend some rod into flat S shapes, that worked really nice.
If you might be doing repetitive work on it (say 4 or 5 plates bent to 50deg) it might be worth considering a work stop for locating the thing to be bent on the bottom die and another stop for press depth. Not really necessary, but if you do more than a couple of things the same way it'll help.
