Agree, this works great!
Visiting an old thread just to say squeezing trailing edges works very well, although I didn't use only squeezing like some people do. For my flaps, I kept every other hole in the trailing edge clecoed, slid the trailing edge a few inches off of the bench, then weighted down the flap skins/ribs to keep everything flat against the bench. I set the squeezer so it would bottom out just above the skin, partially setting the rivet. Once done with the "pre-squeeze" on all of the rivets, I flipped the flap over onto my back rivet plate and used a mushroom set to do the final set. I was astonished at how straight the edge ended up and how much cleaner it looked than the normal method (where I admittedly had some rookie educational moments and dinged the skins with the back rivet set when doing the first partial rivet sets). With the clecos still in and everything held flat against the table with weights, there's no need for proseal or VHB tape either, which was a bonus.
The normal back riveting method obviously works fine. The squeezer method is a great alternative though. I haven't tried grinding down a squeezer set to match the trailing edge angle, only because using the mushroom set and a back rivet plate to finish setting the rivets is so fast and simple.
