How close is acceptable in truing your rims?

I can get it to where it is pretty good - but not perfect. I can get long rubs but not all the way around. I have a little out of round, but it is minor and nothing you can see with the naked eye - but the truing stands tells me it is there.

Is perfect attainable? How much is error is acceptable ?

I can get within a couple of mm's, laterally.

I can get pretty close laterally, hops are another matter. The head wrench at my LBS can get them perfect. I had him build me a good set of wheels and I never have to touch them. He touches them up for me when I have my hubs overhauled about once every quarter. I found that running with 700x25 tires (I ride lousy roads) is easier on your wheel rims...
I've learned to accept a little bit of wobble, if I try to mess with it I usually just make it worse. I've spend hours trying to true a messed up set of wheels, but I don't work on bikes for a living....of course I don't have a real good truing stand, that makes a difference I would think...

You will hear from people with high precision dial indicators going for pointlessly (IMO) tight tolerances, but this accomplishes nothing. My own "short answer" is that if you need less than 1/4 turn of the spoke nipple to remove the wobble, then there's no point in going farther. In practice, that means a wobble that you can just barely see (or maybe not see) if you're sighting down the rim as it spins.

The bladed spokes are another issue - because I have to turn it past then loosen them to get them straight and not crooked.

I spent about 4 hours on my rear wheel last night..

the Park Tool for dishing really helped out.

I keep mine in the 1/4 to 1/2 mm laterally and radially. Sometimes a little file work is needed at the rim joint to get below 1/2 mm. I'm a little bit anal and tolerences this close are not really needed. 1 mm is about the most I would tolerate.

Personally, .5 - 1mm.

Any more is un-noticeable on the bike. Yer chasing less and less returns with more and more effort past that.
