I have hated this rivet puller for many years. It's always physically exhausting for me to pop 'em with this. Half way through the 25 rivets needed to join the left elevator ribs, I took a rest. And while resting remembered that Van's had mentioned using pipes as handle extensions. Well, I don't have those particular tools on hand at the moment, but I do have these inexpensive hand clamps and gave them a try. Amazing! Could use one hand to tighten the clamp and the other to align the puller. Still wish I could find a puller that I could cycle more than a dozen times without a rest.
