Hello all i recently bought a bosch guide bush adaptor so i could use threaded bushes and a set of silverline pc style brass bushes but they're just a bit too big for the recess in the adaptor,the problem is ,is it the bushes that are too big or the adaptor that is too small.I can get a set of pc bushes for around £35 but now i'm not sure if they will fit.Does anyone know the overall diameter of pc bushes if so it would be a big help as then i could measure the recess in the adaptor.Thanks all Rob
