Default Tough set of rivets on tail cone under J stiffeners

Hello, I am riveting the tail cone skins to the bulkeads and came upon a few rivets that I cannot figure out how to set. These are several rivets that join the bulkhead to the skins but fall under a J-stiffener. How do you get to these? Blinf rivet?

In this picture, it is very hard to truly see the rivet is completely under the J-Stiffener. Others were close and I able to use the edge of my back rivet set.

On another note, I clekoed the skins from the inside and back riveted almost 100% of the rivets except the very back of the tail-cone. It came out very nice.

Any help or advice would be appreciated.

I have a bucking bar that has a little foot that sticks nicely under the J-Channel. Something like the top bar in this pic should work although my bucking bar is a lot shorter.

Default Bucking bar use

Thank you Eric. I have a few of those bucking bars. Never used them. I am so used to my tungsten bar. I guess I could break them out. I wont be able to back rivet them though.

Let me try that tonight after my meeting. Hopefully I wont forget to lay down a blanket on the bottom skin to prevent dropped bucking bars from making dents.

I cannot believe how light the tail-cone is getting once all assembled and the clecos are removed.

Thank You

I backriveted most of it as well. Amazing how well the rivets set. I reaaaallly wish I would have figured the back-rivet method out before I assembled my rudder. That piece would have been done in a heartbeat with a better outcome and no ruined skin. (I ended up replacing one of the skins when I backriveted off the edge of the bar after reading countless warning about not doing exactly that!)

I did the same thing - I suggest a little, but powerful, magnet to locate and sit at the end of the plate. Like a neodymium disc magnet. I got several from Amazon and used some for aluminum vice jaw covers.

Michael,

Just realized that we might be talking about different back-riveting methods. I was referring C-Frame backriveting:

Default Thanks - those rivets are done and I am moving on

Thanks everyone for the feedback. I used the bucking bar suggested, with some electrical tape wrapped around it to protect near-by primed surfaces. It worked well.

I have a whole set of various bucking bars but nothing compares to the tungsten. I forgot I even had them.

Let me know how Page 10-21 Step 3 goes for you. I had a heck of a time with the rivets closest to the skin between the Bellcrank ribs and the F-1007 frame. Even with an offset rivet set, I could get a clean set. I finally ended up using pulled rivets. Unfortunately, I buggered the holes up a bit and had to fabricate a doubler, an approach OK'd by Vans.

If there's no clear way to get those rivets done, just use pulled rivets rather than causing yourself frustration...

Default Bellcrank ribs to skin riveting

I still need to rivet the bottom skins in place but most of that should be easy. I will need to phone a friend for the few rivets on the bottom curved piece, then it is on to section 10-21

I was looking at that section a few days ago and was wondering why not attached the bellcrank ribs, 10-21 step 3 before attaching the angle to the top of them (section 10-21 step 2)? Then I would not need an offset set. I could simply back rivet them on place.

Thoughts?
