I'm riveting the gussets on page 29-20 and I've run into a rivet that has me stumped. I've been staring at this thing for an hour trying to see if any of the tools I have will work. I still can't figure out how to set it. None of my four squeezer yokes will work. None of my bucking bars will fit under there. How in the world did you guys set this rivet?
