Some sample Youtube links on bending Flats.
In this video there is a press, but no mandrels used. You can see the potential for how flats can end up with alignment issues. In most workshops the use of a helping hammer is often required to help with the alignment and straightening elements of the build. I was in this position myself before I built my first set of "tools for the job". https://www.youtube.com/watch?v=AI5if5NUklA
And in this link the user has the benefit of a set of mandrels, that are placed within the flats, as the press closed them into place. You can see that the result is already guaranteed to be straight, aligned and true. https://www.youtube.com/watch?v=goBEMJwsIo0
