Hulsroy's Hustle

I can't find a photo of it in action. But I made it as a specific wishbone mitre fixture and did chainstays on another fixture. Both held in similar fashion in a machine vice. But the extrusion fixture required me mitering the dropout joint first individually, which meant they were hard to get right. Now I can clamp the chainstays where I want them and do both dropouts and BB in one go.
