Yet another disk conversion

Still beavering away in East Brunswick I have been working on yet another disk conversion for Riley at Lygon Cycles http://www.lygoncycles.com.au/. Every time I do one of these I start out assuming that I can use a standard disk tab. So far every time I have ended up making a new one. I can see why the most common place for mounting them is the outside of the seat stay and as far as I can see if a big manufacturer is not placing their tabs there they are using dropouts that are cranked upward and have a long section before meeting the stay. Anyway, what the cookie cutter bike makers do is not my concern. Riley wanted his disk caliper on the chain stay so I set about making a tab to match the angles ( and curves) of his frame. Results are below

During our initial conversation Riley had asked if I would put braze a d on the headtube. While I was flattered I don’t really want to lay claim to building a frame that I haven’t. Since Riley is a valued customer and since he will be getting this frame painted himself, I have devised a way to attach a headbadge that can be removed should the owner choose. I should really get some decals made up saying something to the effect of “modified by g.duke” and place them on the chainstay.
