I'm wondering if aircraft mechanics use this type of rivet, and if they'd be likely to have one of these tools. I don't know if small aircraft use this type of rivet, but I do know that "riveting" in general is a big issue, and often a pita in the aircraft maintenance biz.
I haven't been flying in a long time, so I haven't been around the local airport to ask, but I was thinking that it might be worth investigating. If your local aircraft mechanic has one of these tools, you could propose to pay HIM to do your riveting finish-work. I mean, how often do you plan on replacing enough rivets on the exterior of your coach to justify such an expesive tool? You know...you do your repairs, install your rivets, then drive the rig down to the airport, and let him shave 'em down.
