I modified the bolt buster tension tester to test how much force the YABR (Yet Another Bolt Remover) can generate and it's a lot. It broke the bolt but I was twisting hard at 23.82kN or 5,354lbf! This is why you have to score, or aggressively spin, a bolt before pulling so the wedge doesn't get engaged because this can generate enough force to snap the bolt and make your existing hole unusable.
Save money and build your own bolt puller. Greg German generously put all the plans and part list on this forum https://www.mountainproject.com/forum...
