I have been pondering a couple of questions since Rolex, and I think they are worth sharing and discussing.
- Why were there no Mim NewEra Clips at Rolex?
- How do we share new ideas and concepts on “frangible fence design” effectively and efficiently?
I will start by saying neither of these questions is meant as a criticism but purely as points to generate debate. Personally I seek out frangible fences and always aim to have a real understanding of the thinking behind their use, the device incorporated and what will happen if they are deployed.
I think this is good practice for everyone involved in our sport, we all need to know and understand more about these devices.
So back to Rolex, I have had a good look at the fence photos and only the frangible pin was used, both in traditional and reverse installation. The double corners caused a number of issues on the weekend including these incidents below, the second of which ended up being the most serious of the weekend with a dislocated elbow.
So the question I ask myself, is could the either situation have given a different result if the Mim device was used instead of the pins? Personally I think yes, the Mim installed on both front and back could and should have collapsed in both situations. But most course builder and designers, or even TDs have never seen such a fence. I have, at Adelaide last year and I did a video for Eventing Nation on it with TD Andy Griffiths, (while the sound is terrible in parts) and it show how a frangible corner can be built.
So how do we share this information and knowledge in the future?
