I want to preface the following with this... All hubs present a challenge and it's great (and even important) to work towards mastering many different challenges. That said, there are certain 45's that could be considered more "hubable" than others. As a point of reference, the IM Hub-style pinch gripper is approx. 3" in diameter and 1 1/4" deep. The purpose of this thread is to provide those searching for 45's with good hubs (yardsales, craigslist, etc) an idea of what to look out for. Sel
