CHAIN TENSIONER

as the rear wheel will not move, the genuine excentrics, which are inside of the frame are missing and anyway they can't work with this wheel . i'm working on a project of tensioner, with a sprocket, the system is already existing but with a 530 sprocket, and i need a 520 so i bought a lambda sprocket and machined the inside to put a bearing, then made a spindle
another knob, swapped against an old wooden box of taps and dies, BA size
