I am very jealous of you right now. Mainly because I am riveting things on the tank... what a mess. Cool video
 
Nice video !

I got a set of the cheap Harbor Freight electronic headphones/muff. It has a microphone and shuts off when the riveting starts, then you can hear and talk. It is great for doing two-man riveting so you both know what is going on. Really helpful in the fuse.
