I have a question about this... I've had a few split pins corroding through of late, and then the roller on the dumbell falls down and my hull gets scraped!
If using a stainless split pin through the Galvanised dumbell, will the two metals interact? Is that why they are mild steel in the first place?

I always apply maNthematics to my purchases - tell her it cost a chunk less than it did, then tell her I got a chunk more than I really did for the one I sold... The new purchase seldom costs a penny...
