Re: Riveting up a frame

177 Uses POP rivets in similar ways to what Paul said above for 217. We also use solid aircraft rivets installed with a pnuematic hammer and bucking bar in application where higher shear strength is needed or if we need the rivet to be flat headed. We have made arms capable of lifting a robot of the ground this way using aircraft construction methods. Needless to say we believe the strength is there.

A word of advice if you plan on using big diameter rivets is to get a pneumatic tool for installation. Particularly if you use a lot of them.

Just a general comment, we find a mixture of joining using welding, rivets, rivnuts, and nut/bolt fastening depending on the application gives us the best solution for the problem. Don't rule out any of these methods unless you are not properly equipped to do them.
