Don,
I never considered backriveting. I have been shooting them from the outside.
I don't own a long backrivet. The other 4 or so rivets shot fine the conventional
way.

Paul,
What I did was to use the avery "long backriveting set" I used a heavy hand
held back rivet bucking bar on the outside and the long rivet set in the gun.
This will send all energy into the rivet. Don

Fellow RV-9/7 fuselage builders,
I am just about complete with my riveting of my RV-7 fuselage (upside down).
I am having troubles setting the forward most AN426AD4 rivet that joins the
side skin, bottom skin, longeron and firewall weldment. I have tried several
different bucking bars. Most of them are lighter then I would normally use to
set 1/8 rivets, but due to the flanges on the weldment I can't use my larger
and heavier bucking bars. I believe most of the energy is going into the structure
and not the rivet. I am using a 3X gun and running 50 psi.
Any thoughts?
Paul

Or just try running 80-90psi. The bucker is gonna feel it for sure, but it'll set
much more quickly and the rivet won't tend to work harden as quickly.
When shooting 1/8" rivets through "thick" structure, I always crank the pressure
up. I'd rather hit hard for less time than "soft" for more time -- I believe
it's less of a beating for everything around it. Just my 2 cents.
In this area, I used the "L" shaped bucking bar from Avery. It's lighter than
I would like for the given task, but like you, I was constrained with respect
to the bucking bars I was able to get in there.

I use around 65 psi on AD4 rivets ... particularly the longer
ones.
