how to shoot this rivet?

[Desert Rat]

How the heck did you guys shoot this rivet? I must have 15 bucking bars including a couple made from tungsten helicopter mast weights that aren't much bigger than my thumb, and I cant figure out how to get any sort of bar on the back side of this thing. I can barely get my finger on it without a bar?

It's common to the skin overlap, longeron, and the strap that ties into the F-704 Vertical member, so I suspect it's kind of an important little fella. I'm going to call vans this afternoon and see if they approve a pull rivet here unless somebody offers up a better solution before then.

Put a Cherrymax rivet in there. I had to use several in that area on my 6 due to access problems.

What Stew said. You can fill the center hole with epoxy so it looks fine under paint, then build on!

The Mothership can offer specific cherrymax options, of course.

Will the strike plate to your back rivet set fit in there? I used that in some tight fitting places. It took a couple extra bursts with the rivet gun but it worked fine.

For this rivet, and the rest of them along the side rails, I used a squeezer yoke for the bucking bar.

No CherryMax in 3/32. You might ask Vans about going up to #4 and using a CherryMax.
I have a variety of home brew bars. I have a thin tungsten that fits almost everywhere. I often taped the heavy tungsten to it for extra mass.
The tight spots were done with a piece of steel thin enough to fit. Even a flat blade screwdriver will work. The heavy tungsten was taped to the steel bar as close to the impact point as possible. It adds the mass. Same problem with rivets near the roll bar if you have a slider.

I think this would work.. while not a Cherry Max, its a Cherry..

Not structural. I have some. They are marginal for holding nutplates. Best ask Vans if it's approved.
A MK-319-BS would be stronger but the grip length probably isn't long enough.

I did not use a cherry max for anything on my build.(RV9 and RV7 have nearly same fuse) But I did use the end of a squeezer yoke, and the end of a chisel backed up with a bucking bar. Some required creative thinking.
