I have recently purchased this riveter and it has worked well. it will set a 3/16ths rivet with ease. I use mostly 1/8", so it will probably last forever, which is really the only concern that I have. I usually shy away from taiwan tools, but a US built rivet gun is $500-1000, and I just don't use one enough to spend that much. I will say that import tools from taiwan have made great strides recently(a vast number of companies in taiwan/china are former US companies that moved overseas). I will do an update later, but it has been flawless so far.

This heating Air Riveter for riveters - a challenging, dangerous skill that entails heating rivets until they are red-hot, and then throwing them through the air to a waiting catchman who puts them through steel beams with a hammer or a pneumatic drill, is a marvelous, compact design that can be pulled even by horses.

br /Most buildings today are constructed with iron and copper tubes, protruding upwards into the skies. This Air Riveter is mainly for small jobs such as rebuilding an 8 story garage but ask any iron worker if he can use it on say, a larger job and he'll smile at you and show you his Union badge and then ask for a 15 minute break.
