I just sharpened and reset my jointer blades. I checked (dial caliper) that
the blades were level with the outfeed table and one blade is 0.001" above
and one is 0.002" below (the other is level).
Obviously having all at 0.000" above or below would be ideal, but I still
want to keep the little hair I have left on my head.
Do you think this is acceptable? Will I notice this when jointing?
I assume the highest blades will wear the fastest and maybe "catch-up" with
the low blades with use as they dull.

In fact, that's not possible. There will always be some error, however
slight. And ... I'd not presume that any blade is precisely straight.
Meaning: within zero tolerance.
This is not metalworking. Being within .005- .10" and being consistent
is excellent.
Fussing about a blade measured radially off by .001" is obsessive.
IMHO.

Just to confuse the issue is that on both sides or in the middle.

I don't mean any offense by this so please don't take it that way. I am
responsible for training new hires at work (machine shop). I have been
machining for over twenty years. I am also told that I am a rather good
teacher but, it is the rare individual that I would trust to take a
measurement with dial calipers to that kind of accuracy. There are too many
things working against you in that situation. I would say that it is
probably closer than you can measure which is very well close enough. The
blades will wear .003 in very short order and they will even themselves up.
To set them any closer, I would recommend a dial indicator. Not totally goof
proof but, I don't see you as a goof either.

I think the "low-tech" type of setting that
measures cutter height by measuring how far a
blade moves a stick is pretty good, but I'm no
professional.

In my experience you start getting chatter somewhere between .05 and .15 mm.
Depends on the width and hardness of the wood.

Nope, doesn't confuse anything.
I set my knives using a magnetic jig like this one:
http://www.amazon.com/gp/product/B0000223DS/002-5014446-8071214?v=glance&n=228013
It ensures (in theory) that the blade is parallel with the outfeed table.
Therefore, the blade measurements should be (and usually are) the same down
the length of the blade.

Thats what I thought regarding the wear. Thanks!

Yep, I used a dial indicator, not a dial caliper like I wrote!
Thank you!
About .007.

I dunno nothin' 'bout settin no blades. But this guy does:

OK so you probably do have the measurements right. In any case, I would call
what you have close enough. Consider the magnitude of the error.
