I just got one and will be taking it back. I wasn't expecting the performance of a Yoder or a Pullmax, but this is anything but a planisher. It will stretch metal, but looks terrible. This tool is supposed to planish but it only dents. A 6" or 12" radius anvil might help, but it only comes with 1, 2 & 3 inch anvils.
The air tool also comes loose too easily. I've cranked down the single allen head screw to the point of stripping the threads and it still pops loose. It's too CHEAP in quality.

You need to have a compressor that can deliver about 90PSI. As you can imagine, it's a pretty big air hog as the hammer is running continuously. I'd imagine the minimum would be a 30 gallon tank to have enough reserve to not be wasting your time. Most of the metal that I form with this is about 20 gage, but I would think that you could run 16 gage with it with some pre-forming.

Maybe your technique needs to be worked on? I've made many panels with this machine and have had to do very little in the way of finishing. Certainly, it's not to the same smoothness as panels that have been wheeled, but if you work carefully, you can get a very nice finish. Adjusting the height of the tool is critical for this tool to work properly. If the hammer is coming loose, you're not adjusted properly. The hammer needs to contact the piece only enough to shape material against the anvil.

You also have to be aware that this tool won't work on heavy gauge sheetmetal. If you're trying to work .070" you're going to be disappointed. Make sure that your anvils are polished smooth as well.
