Clekos

[carbon fiber]

They make a pneumatic cleco tool if you get tired.

BTW - I disagree that clecos aren't as tight as a rivet.

Bucking real rivets and installing cherry max or pop rivets is apples to oranges. Clecos aren't as tight as rivits. The clecos only grip from two points, 180 degrees away from each other. And they only have so much pressure. Most kitplane builders have never bucked real rivets, especially on structural parts thicker than 0.80. When you have a hole that doesn't perfectly line up you then re-drill. Then when you go to buck the rivet, it wants/has to fill the offset that was created when it was re-drilled. That makes the rivet want to lean to one side while your bucking it, which is a major problem. This isn't an issue with simple panels and pop rivits, but it matters big-time with real rivets. I would bet I've used more clecos than anyone here, last time I checked I had over 1500 of them.
