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.
Seldom do pictures provided give an accurate assessment as to their "hubability".
With enough contributions to the thread, it could become a decent resource to direct people to.
If you have a 45 that you consider to hubable (not yet already included in this thread), please upload a picture...with the following...
The brand name
The hub diameter
The depth of the hub.
The approx. difficulty of pinch feat. (easier, middlin', harder)
I shall begin...
3 1/4" diameter
1" depth (approx)
