Little help with riveting

[Huck]

Let me ask another newbie question:

When does one use the 2x gun? When does one use the 3x?

I searched the forum but no joy.

Thanks in advance.

Assuming you have both sizes...

Use the 3X gun on larger rivets where there is a lot of structure underneath them. Say along the longeron.

Use the 2X gun for smaller rivets and skin to bulkhead or skin to rib rivets.

I built my -9 with only a 3X gun and a friend built his -7A with a 2X. If I were to build again, I would use both.

Having used both sizes, if I had to pick one gun for the project, I would stick with the 3X. It can be turned down to drive the small rivets and doesn't have to beat the large ones a million times.

Rick,
I rivet solo because I still don't have a partner and using the offset rivet set was almost impossible.
As you, I started riveting the ribs to the main spar with a double offset rivet set and the result was like your one... smiles!

I solved using a 7-1/2" long straight rivet set. This way I eliminated the need for a (double) offset rivet set and the partner on riveting the ribs to the main spar. There is almost no need to flex the rib apart riveting this way.

It worked very well for me.

When setting AN470 (button head) rivets, I found it helps if you put a small piece of duct tape on the rivet set.

Also, airpressure is key!
