Re: What's this called in english (nails)?
where would one get new ones, and are they just "hammered" back in ? - any info on that?
You'll have to get a rivet the same size, then peen the opposite end from the head, over.
Normally the rivets are a hard rivet, and the only true way to peen or roll the other end is with an "orbital riveter". Seeing that the average person doesn't own an orbital riveter, you'll just have to try your luck peening one over. If you don't have the proper shaped punch, what you will need to do is take a flat punch, and start working around the edges rolling the edge over. You'll have to do this all around the rivet quite a few times. The other way, if you have a lathe, and again, it is dependent on the rivet diameter, you would have to dish out the end of the punch, then keep working the punch around the rivet while constantly tapping the punch.
If you ar working in a factory that does assembly work, ask one of your friends if they have a TAUMEL RIVETER. That is the most common brand name for an orbital riveter. It takes a lot to roll over a hard rivet.
For one, you will be working with a hardened stainless rivet instead of an aluminum rivet.
Good luck and let us know how you come out. If you get the rivets you need but don't have or can't make a punch, let me know. I've made quite a few thousand over the years.
