Grinding away that surface corrosion

Lydia has been helping with the progress of the 1951 Riley RMB. There was surface corrosion on the inside of one of the original wings round the edges of the spot welds done by James. Lydia did this with various-sized grinding attachments on a drill. A small step in the process, but a vital one, nonetheless, since we don’t want that surface corrosion getting worse or showing through the paint when it goes into that stage.
