Firewall mount weldment 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.

Firewall mount weldment 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.

Firewall mount weldment 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?

Firewall mount weldment 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. )_( Dan RV-7 N714D http://www.rvproject.com ----- Original Message ----- From: Merems To: rv7-list@matronics.com Sent: Saturday, November 12, 2005 7:07 AM Subject: Re: RV7-List: Fuselage riveting help?
