| I remember a rather pricey set of Mag yokes cracking when a set of nicely anodised forks were bolted into them, this was because the original anodised finish on them had been skimmed off by turning them down in a lathe and then re-Anodising them, the slightly smaller diameter that was left over stressed the mag yokes as they tried to clamp around them.
To me either skimming the surface or disolving it is still damaging the alloy So goes against what was called for in the original post
