I have to admit I rarely use a bending brake and have never made a box before. It would seem problematic to me to do this because the three sides of the box that are already bent might prevent the 4th side from being bent because the other folds will get in the way.
If you watch the following video of an amateur making a box, you can see that he has this exact problem at 7:56 even though he has a pretty sizable brake:

In the next video we see a professional making a box but the brake he uses is enormous:

So, is it just a question of having a gigantic brake? Is there any easy way to compute how big a brake you need to make boxes of particular dimensions?
