Greetings.

It's possible with a mushroom set, but it's tough to do. When I caused a dent in that area, I tried using a 12" long backrivet set on the manufactured head to clear the flap bracket, yet caused another dent. I put those rivet sets aside in favor of another approach...

I used a longer flush rivet set when I did my bottom skins. This is a 5.5" flush set with a 5/8" surface obtained used from Yardstore. They don't appear to carry it any more, but it looks like Brown Tool has the 5.5" flush set. Yardstore also 3.5" and 7.5" long flush sets. The latter is probably too short as it may not fully clear the bracket.



Here I am riveting the left outboard bracket with that 5.5" long straight rivet set.

Default Edit-

I had an offset cup set and I had already ground for another issue so I prepared that for this task, but. I ended up removing the retainer spring from the 3X gun and used a mushroom set WHITHOUT a rubber guard so I could get as close to the flap bracket. This worked okay, not ideal but good enough. I would want just a bit better or easier method if this were on top.

Default That’s cool

Is it me but Emerit’s technique looked good but the fact he got to build inside the house is more amazing to me.

Same problem on the RV-10 and RV-14. This is what I did and recommend:
- Take a 1/2” x 1” or so piece of .125 aluminum, run the edges over your scotchbrite wheel.
- Drill a #30 hole biased to one side. Use your deburring tool to make a small countersink on one side. Insert a just slight linger round head rivet and set so that the shop head is flush with the back side of the aluminum. Buff smooth.
- Add clear packing tape on the back side.
- Tape your now finished custom rivet tool over the rivet you want to set. Have the round head right over it.
- Use your long round head rivet set and drive the rivet.
- Repeat as needed.

Don’t throw away that custom rivet tool. I’ll rent it from you for a six pack of Sierra Nevada......

Now that is out of the box thinking!

On the road but will take photos of making one. Think really simple and you will be there.

That is absolutely brilliant! Wish I'd thought of it before doing my bottom wing skins. Mine came out OK (they'll look fine under paint!), but undoubtedly not as nice as yours. Great idea!
