On the rotor side I won't have the 1/4... It’s such a tight tolerance that I will only have a few thousandths between the rotor and brackets. I’m not a welder but the idea was to weld the inside edge 360* where the DOM meets each bracket. I’ll leave the fillet to the fish ….
I flexed my MS Paint photo-chop skills... the RED in the pic below is where it will be welded... the other side is the same but cant be seen at this angle...
