I need gears of all shapes and size for use in some of my creations, some will be working, some will be for decorative purposes. Does anyone know of any breakers yards in the Herts/Beds/Bucks area where I can pick up old gearboxes cheap? Are there any other places where I would be likely to find old machinery? So far I've been extracting bevel gears from burnt out angle grinders. They will come in handy but are on the small side.
