Help with rivets please

I use these kind of rivets at the body shop all the time. It doesnt happen all the time but it does happen ocasionally with them. If you are using an aluminum rivet with an aluminum mandrel I would just nip the pin off and file as someone has said. SS will be harder. The problem lies in the strength of the pin. Not neccessarily the tool you are using. It happens to me using  a window glass rivet that has an aluminum body and a steel pin. Another thing you can do is take a small punch and drive the pin back through the rivet and seal the hole with silicone or aquaseal.

   Thanks for the help everyone! 
I think my problem was a combination of a narrow grip margin on the bucket only, and the fact that I am mildly tooltarded and was using the wrong nipple adapter (heh heh nipple).

"tooltarded"  thats awesome!

LOL

Sounds like a " grip range " problem, you also might want to put a SS washer on the bottom side as a backing plate. Good luck.

It looks like you pulled the mandrel head (the silver part that looks like the head of a nail) through the trifold rivet body (the black part).



When the mandrel breaks, you should still see the head of the mandrel at the end of the rivet body as shown here.



And you should not have a half inch mandrel sticking out.



This is usually caused by using the wrong size (too big) adapter for your rivet. When this happens, the mandrel left sticking out is usually loose because the rivet body has been damaged. With the head of the mandrel pulled through, there is nothing preventing the trifold rivet body from collapsing back down, and the rivet pulling out. I would remove the damaged rivet, and try again.

The differece in the adapter size makes no difference other than to algin the mandrel with the jaws of the rivet gun better. The hole on the adapter doesnt cause the head of the mandrel to pull through. Its just a bad rivet. In that case the madrel is too strong of a material comapred to the shaft of the rivet. Dont get me wrong though you still need to cover the flange of the rivet head.
