I had the fork leg on mine built up(TiG) so as not to distort it.
I'm surprised your method worked Richard. I have an A65 wheel in mine and had to put grooves on the spindle further out, as the legs nipped up. I suppose though, as yours didnt have an extended lug the pinching in was more gradual because it occurred over the full length of the fork, rather than between lug and spindle.
