Securing long boards on edge

My trusty Wolden holdfast securing one end of a 5' board.

So, I finally figured out a fool proof way to secure long boards to the edge of my work bench. My bench does not have the legs flush with the edge of the top or have a sliding deadman. I asked my wife for her opinion on this predicament and this is what she came up with.

This is what a fresh set of eyes can do if you ask for help. The other end of the board is held fast with the face vise.  Happy planing !
