hey dirtdrop.
that's a great picture btw.
thanks for the info. i'm having a hard time understanding how that tool was used. the clamp looks almost as wide as the fender. you just grabbed and bent the fender edges, right? i imagine you clamp the tool perpendicular to the bottom of the fender and bend in?
i thought of laying the fender on a thinner wheel or rounded object and tapping (hammering) a small pipe against the feder edges, at the chainstay points, to crimp/dimple them.
i'd rather not buy a tool for this purpose - especially seeing that i already have to return the tin snips
