It's good job the plating stops 3-4mm before the bend at the bottom of the bracket then. Have another look at the pics where his finger tip is.

Just like to point out guys that I have not welded nor intend to weld any metal that has already been plated as talon mentioned I stopped the plating short of where I am intending to weld and although the way I worded an earlier post make it sound as if I had with the bush tubes I had not, because I used a detail sander to remove the nickel....we are after all taking about 5-10 microns of nickel a very very thin layer which I have protected with clear lacquer I had read about embrittlement but this was always associated with the acidic electrolytes particularly sulfamic acid but even these were talking about high temps and much thicker plate.
