I am humming right along with my Klunker build, which I am using a Worksman M2600(large) frame. I am having an issue with the Nexus hub though? The frame has rear facing dropouts that slant downwards, and it's driving me nuts trying to pick the right non turn washers for it. When the shifting mechanism is sitting straight with the chainstay, it "looks" like I need an 8L and 8R. Has anyone put a Nexus hub in a later model Worksman frame? At some point they went from a horizontal rear facing, to the angled downward style. To me it looks like they just turned the dropouts over and started brazing them in that way instead.
