I think cable tieing my 4 bolt mount together, then cable tieing it down to the frame at the start of a london ride, then keeping it on for a good few weeks was my best, basically stripped the mount as i got to the meeting point IIRC... Adrian from norwich had cracked forks, so he jubilee clipped a snapped tensile crank to the back of it, and 2 metal tyre levers to the front of it. That, was cool.
