Default Rivets in Rudder Horn Brace

Almost done with my rudder. Yahoo!

I can't for the life of me figure out how to set the four AN470AD4 rivets in the rudder Horn Brace R-00910. See the drawing here:

https://www.vansaircraft.com/pdf/rev...4/RV-14_07.pdf

page 12 of the PDF (or page 07-10 of the plans.)

I don't think a flange-nosed yoke would fit the corner rivets. I'm thinking I need to purchase or fabricate a custom bucking bar?

Any ideas?

Thanks.
Chris

I have just completed this part and used the Tungsten Mini Bucking Bar, it has become my favourite bucking bar to use, and wish I had got it a long time ago

I just completed this section as well. I struggled with how to get to these and found that a longeron yoke on the squeezer was able to get to all but the bottom corner on the skin sides. For those 2 rivets I used a mini-tungsten angled bucking bar.

I was able to get these with the longeron yoke on a "main squeeze". It was tricky

Default Tungsten bucking bar

This is the little jewel I'm using on the new RV-8 project. Worth its weight in gold. The ETBB04 model: http://www.tungstenbuckingbars.com/prices.html

It is small enough to fit in those places a standard bar will not, but still have the mass to buck.

From figure 2 it seems like they intended for you to rivet those 2 pieces together before putting it together with the rest of the rudder assembly.

Have you found this rectangular shaped one to be generally useful? I have this one:
http://www.cleavelandtool.com/Tungst.../#.WA4kzPkrKUk


But do wonder which one to get if I get a second one. Yes I know you never can have enough of them But at $100+ a pop two will suffice.

Opinions? I am working on the rudder right now.
