In my younger days I once arc welded on a pair of mudguard supports to some early Triumph sliders. This resulted in two very banana shaped sliders. I was lucky in that I worked for a large engineering company that had its own flattening and straightening section - they had their own hardening section too. A rather large gent named Hippo somehow straightened them for me and I was told not to be such a silly boy in the future, or words to that effect.
I wanted to fit a Yamaha tls front brake to the same front end, so asked his advice. He got the anchor slot welded up and made a stainless p clip to suit a previously drilled hole in the brake plate. The cost was I buy his drinks Friday lunch time. I found out the real reason he was called Hippo
