Edge Retention/Rolling Test Stand

[grepper]

Wow!  That's quite an impact on the edge for just gently lowering weight onto it.  I'm a bit surprised and thought that something like that would require impact of some sort to cause that amount of deformation of the edge.  I would say that data is indicative that you are on the right track.

If that test apparatus was sitting around my shop for very long I'd no doubt knock over that container of shot. Doh!
