One of my trick bike forks had been broken for a few years. I always had it to show people how it can just break. As I now have the trick bike frame that Zack made out of bamboo I thought it might make sense to have this extra fork working again. So I gave it to a welding guy and I told him the fork opening needs to be 100mm. When I came to pick it up it was actually 107mm and optically asymmetric. I asked him if he could do a better job and he said yes. Watching what he then did made my less confident and even after all his efforts it still is 106mm. I will need to try it out like this or find a more professional welder. Here is a picture of him working on my blue fork.
