Although not a tool that is technically needed, its well worth it. Gives a third hand, especially in tight spots, that allows better quality squeeze on rivet, not to mention efficiency dimpling and riveting. Buy it, you won't regret it. Cleaveland tool and the manufacturer provide great support. One can always do without this, but I'm generally frugal, and I have no regrets.
Recommend getting 3" and longhorn yoke at a minimum. No hole yoke and 2" very nice, but one should know its high cost for low use, but I'd still buy them again. If you want to do your best work, always use the smallest yoke and the longest rivet set you can. I was getting so so results until Mike recommended using the longer rivet sets on the manufactured head...Results are beautiful. Lowers the amount of flex whether using pneumatic or hand squeezer. Also, make sure rivet set in manufactured side is roughened up (use the sidewalk trick)....that will result in more grip on that side, and less slumping over of the rivet. Thank you Mike for supporting all of us. Your tools, knowledge, and support are highly valued.
