Think you can find anything on the Internet? I Googled "how to use an offset rivet", then searched Youtube----nothing! No one in the entire Internet world is willing to video themselves using an offset rivet set!

Agreed, once I had a partner bucking and held the offset with an "iron fist" it worked well.

Offset with Avery's Snap Socs worked great for me, even solo. Just turn up the pressure by 10-20 psi.

Use electrical tape to hold the set in the gun. Wrap it tight enough to hold the set from turning. This will solve most of your problems.

Well, I can be satisfied with VAF today, I learned something. My offset success is very low. This is now on my "determined to learn this skill" (or else) list! Right now, it is avoided and feared.

Thanks Tom.

Ar you guys talking about an offset, or a double-offset? I have been using the double-offset quite a bit this past week while riveting the seat and baggage ribs. I have found two things that help. First, turn the air pressure up 5-10 PSI to make up for the increased mass of the rivet set. Second, you can't be shy about holding pressure on the gun. I had a few smilies (which did not leave ME smiling) trying to use it on wing ribs. You gotta show the gun who's boss, or it will bounce off the manufactured head and the results are not pretty.

I've never used a regular offset (one bend) rivet set. That looks like it would take a lot of practice.

I was bad-mouthing the double offset. I could get good looking rivets, but if you mark the hole center line prior to driving the rivet, you may find that the head has shifted (sheared) in the hole. This would seem to not be a good thing.

The oracle from Aurora has spoken:

"This very minor ding doesn't merit any worry, nor replacement."

I connected with a tech. adviser in my area and he had the same suggestion as Tom--use tape.

I also didn't think to turn the pressure up. The large set did take a lot longer which upped the odds of a mistake.

Thanks all.

Electrical tape is a bit stretchy, duct tape works better. Spiral wrap tightly from the end of the gun over the spring and onto the set.

You'd be surprised how little tape over the spring area is needed.
