20mm through axle, built with tapering blades. This is actually something I've never done before, but I think it came out looking pretty neat. Note that the ugly-ass bolts in the binders are the ones I use when welding/brazing, they will be replaced with nice pretty ones before the fork goes out.
I'm sort of working on two frames at once right now, which is usually something I try to avoid, just because I'm easily confused. Going to work on finishing up John's FS bike (pictures to come) today and tomorrow while I wait for some parts for Arne, then move on to that project.
