Скачать или смотреть US-Box Windsurf Fin repair using Metal Spare part

I broke my favourite US-Box 39cm carbon fin in the shallow waters just in front of Antoine Albeau´s Windsurf school ( https://goo.gl/maps/P86RC6zuQhzVNqnF7 ). It was almost new. The head of the school, Jean-Marie Albeau pointed me to the windsurf shop "Neway" in La Rochelle ( https://goo.gl/maps/ygTYFFW8d6PYJi7z7 ). And indeed they had a very last sparepart available. Luckily the fin was equipped with this metal piece before, so I didnt have to grind and sand, just exchange the broken metal part. But in case a viewer breaks his conventional US-Box fin the same way and is lucky to find this metal spare part either new or on a used fin on ebay, he can repair his favourite fin using this easily just by grindung the fin´s head down a bit and drilling the required holes.
