Thanks
All good ideas and many thanks.
I was in the local hardware this morning and had a rush oif blood to the head when I spotted some of the new types of sanding discs for angle grinders.
I bought 2 types - one was a disc with a whole heap of small overlapping sheets of sandpaper arranged around the circumference like the inlet fans on a jet engine. The other was a disc with a thick brillo-pad sort of thing, a hard blue scouring pad sort of material. Becasue I'm working on the inside of an 8" tube, these both looked promising. Having now done the job, I can vouch for both but strongly recommend the scourer-pad type. As the pad wore down at the edges, it conformed more and more to the inside shape/profile of the tube and became more effective as more of the pad came into contact at any given time. It really ripped the dickens out of the gunge in there and brought it back to nice clean and shiny steel in no time.
Peter.
