Bought a pistol-grip pneumatic cleco tool today from Avery Tools. I used one of these in the Grov-Air RV Construction Skills class and loved it. Almost as handy as the pneumatic rivet squeezer. Took a bit of time to free up the screw-on head so that the end of the Cleco-holding tip would rotate 360 degrees. For some reason, when the tool is shipped to Avery, the screw-on head is locked down with thread-lock compound. This has to be loosened up to allow the tip to rotate as intended.
