12 forum posts	I have aquired a couple of Aluminum vintage pulleys. They are probably 30 years plus old, possibly from car engines. Apart from slight oxidation they look in good condition. It is a good idea to put them in a oven for a while before machining them ?

I just made some alterations to a pulley on an old drilling machine and I know the pulley was 50 years old -- I fitted it originally. John
