It looks very good. It's a very interesting project! I am looking forward to seeing more pics of the whole process and the finished bike
I guess that doing proper weldings for the rocker bracket requires removing everything else from the frame (and then repaint, at least on the affected areas!), so it looks like a lot of work.
Also, I don't know what kind of tube is used on the CB, but some steel tubes (e.g. SAE4130) require heat treatment after welding for stress relieve. Otherwise, the strenght can be compromised.
Regarding the lower end of the damper, I can't see it on the pictures: does it react against the swing arm, or it requires you welding an additional bracket to the frame?
