Triumph Pre Unit Timing Wheel adapter

If you have a pre unit Triumph then this is a handy adapter to mount your timing wheel onto the smooth end of the crankshaft. Slide it over the crankshaft and snug up the big nut so it doesn't slip. I made two versions, V1 just use a small screw to attach the timing wheel to the adapter, V2 uses the small nut to attach the timing wheel, users choice. I have included the Sketchup files in case anyone needs to adjust the inner diameter for their crankshaft.
