ArtMetal

Thanks Valerie,
My first guess would be that there was still some cutting fluid inside the tubes. I cleaned it all then wire brush with a stainless brush. So I do not think it was rag fuzzy bits. I have brushes for each type of metal clearly marked.

I'll run some tests before I start the next project. Although you know they will work perfectly it won't be until I'm working on an actual project that I'll have a problem. ;-)
