Sometimes I build items that require blind rivets. I've owned several hand held rivet guns, most recently a professional gun that was expensive but had the leverage needed for large rivets. The problem is that if you're putting a lot of rivets in, you need Popeye's hands to do it. In view of major work, I bought a Milwaukee Power rivet gun. Game over. It is very easy to use and works very well. Couldn't be happier. This makes any job that requires riveting much easier and faster. Although it has a certain weight - it is well made - it is not tiring to use. My only regret is that I didn't buy it sooner.
