For the record I'm going to end up fabricating clamps but honestly most of the people against the idea don't really provide much to support their position. I'm not saying they are wrong but they are not offering much to prove that they are right either. There were some good comments on the importance to avoid crushing forces and vibration that would create unduly stress in the hole.
