Hi, I recently had a very frustrating experience trying to set 6.4 x 16 monel rivets with lazy tongs. I managed 2/5. Having learned that not all riveters are equal I am eager not to repeat the experience and I'm looking to buy a more muscular tool before I go back for round two. The info given online never mentions monel rivets, I suppose they are more rarely used. I have seen some riveters which specifically say they will set stainless. Is this a good guide as to whether they will cope with monel? Finally the cost of hand tools that look like they might cope is not that much less than the cheaper end of the air tools. Is it worth paying a bit more to get an air tool? It's not going to get a lot of use, I'd just like to buy a tool that's painless to use and not going to need replacing again.
