Thanks m_c
I didn’t know that it would still corrode with stainless steel there is no point in using it then so I need to find a way to keep them apart then, perhaps using some sort of bushing any idea what I could use that would not wear and could be made on a lathe.
Sorry if the question is very basic but I am a vehicle body and paint man and not had much to do with lathe work for about 50 years and even then it was only basic turning.
Thanks Dell
