Z bracket nutplates to Spar

[rapid_ascent]

I'm wondering about the best way to rivet the nutplates for the inboard tank Z brackets. This seems a little tricky. Squeezer can't reach. Do I use my back rivet set? I started trying to do that, but it seems like its not working well. Any suggestions would be helpful.

I just bucked them normally. I used a mushroom set and my tungsten bucking bar. It is a tight squeeze in between those ribs right there, but mine came out fine.

thanks Gil that seems to work better. I guess I was trying to make it too complicated. I forgot I had the tungsten bucking bar. I'm not sure I'm sold on it but for this job it seems to be required.

no hole

how about a no hole squeezer yoke. thats what i plan to use.

The squeezer can't reach around the spar. The reinforcement is too thick at that point of the spar.

Just buck them...easy enough with a tungsten bar.
