Wheel building again

Seeing as how I sold the USD forks, I am going to combine the stock DR400 forks with a twin-leading shoe front brake (ex CB175) and a sun rim 17x2.75. Sometime ago I ordered some custom spokes at 146mm long but they just remained in their packet till today. Turns out that all these parts do fit together fairly well. Things to do include spacers to allow the 12mm axle to fit 15mm bearings and a bracket to mount the brake stay. By my calculations there should be enough room to squeeze a 110 wide tyre in.
