For what it's worth I think the brake anchor is brazed on, not welded.

your probably right but i can weld it on for now with minimal heat and paint damage . May well change it later but want to try it first .

A "cold" weld (small area high temp) can produce brittle edges in steel with any carbon in it. Nev

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 :o

As the brake , under load , would be turning anti clockwise , left side , the support is going to use the fork as a stop . In this photo it only shows a bracket from the bottom mudguard bolt holding it in position . If I use a similar support so that the fork leg is the stop I could probably do away with any welding . I think that should work and the bracket is only to hold it in position . This would go against my nature though as I have been a time served welder since 1978 .

Good Lord that's a piece of work !
Did you use a Keyway Broach to cut those slots ??

My first thought was to use a choke cable splitter - then I realised that this is for brakes so needs to be substantial. Nice job !

I did it all with my milling machine but I broke my only 2 mm milling tool when i did the top slot so the rest were done with a drill as you can see at the bottom slots . But where theres a will theres a way .
