Hi,
There wastalk here recently about how some coolant went a funny colour owing (maybe) to a component of the swarf being leached into it. I want to make a drain rose / strainer for my lathe and in the light of this I'm a bit concerned about what metal to use ? I obviously don't want to pick a metal that will go rusty or suffer from the symptoms described above so what is a safe metal to leave in suds all its lift ?
Thanks,
