yeesh, what's a ballpark estimate for the likely cost of rethreading? that doesn't sound like something my corner shop would be competent at.. maybe I'll just live with the old fork.
is oxalic acid likely to damage the chrome/paint? it's already in dodgy shape. I think the paint on the crown peels when I look at it.
