I think that if it is going to be that much trouble, I'll make a long
ways grinder and let it run in automatic.

I think that for the simple version, grinding/sanding the high spots
would get it more than 80% of the way. then schims would do the rest.

I have given thought to spot facing the bolting holes and using large
fat washers, but that would make the whole rail elevated.
