oxygen starvation???

Welcome aboard.

What type of cutlass were you using to start with??? Straight? Spiral?

Some older shafts were made of 304 stainless and did indeed suffer from corrosion due to lack of oxygen. I have one.....I rearranged where the bearings ran and made sure that plenty of water was getting through and stuck it back in !! Not brilliant science but you will find that 304 is slightly magnetically attractive, but 316 is barely detectable. Another use for your fridge magnet..... (Australian joke). By the way l have just relized that l am not doing my job very well.
