I ran into a curious situation today. I have some trivial but significant
alignment problem with the left wing of my table saw. I was attempting to
gauge how far out of whack it is by comparing two levels.
For the first level, one of those orange deals with three vials in it. I
used this to level the saw initially. It reports the saw as being level
all the way around. If I move it out to the waffle wing in question, and
position it appropriately, it also reports the wing as being level all the
way around. Whatever difference there might be is too small to gauge with
this method.
So I thought I'd look at two levels simultaneously. I grabbed the head off
an old combination square, that I use for sundry low quality purposes. Put
it on the table, and it showed a huge amount of tilt. Put it on the wing,
and it showed the same huge amount of tilt.
Then I got the head off my good combo square, and it showed the same as the
first one. Grossly out of whack level wise.
I just don't get it. Why would one show perfect and the other show that the
left side of the saw is almost 1/4" higher than the right? That's a huge
difference. My first thought is length. The orange 3-in-1 level is about
3/4" longer than the head of a combo square. My second thought is the size
of the bubble. The bubbles in the combo squares are a bit larger, and the
vials are a bit larger too.
Just for kicks, I also tried with a bullseye level. It shows level all the
way around too.
Weird. No, there's nothing stuck to either of the square heads, no hardware
protruding; no reason I can discern why both of them show such a huge
difference from the other two levels.

OK. I'd start with Wittgenstein but then move forward in time a bit
to Foucault (not the pendulum dude, the other dude) then go backwards
to Russell, Kant, and Descartes.
Steer betweeen the Scylla of Phenomenology and the Charybdis of
Dialectical Materialism.
Follow this line through Aquinas, thence to Aristotle, and at this
point you should be able to figure out which tool to use to deal with
your alignment problem.

Andy did better than I did. I managed to pick up the 8" No98 off eBay
for Au$90 (US$65), brand new. Very nice thing to have.

The advice already given is good. The levels in the heads of
combination squares aren't usually that good. Another thing to consider
is the length of the reference surface on the level. I don't know what
sort of orange level you are talking about but if it has three vials,
it must be longer than the face on the combination square head.
The orange level may report a level surface but keep in mind that could
be just between the two ends of the device.
If you want to confirm what your first level told you, you use another
level of the same length.
If you want to adjust the wing with the table, you should be using a
different measuring device. A level, even an accurate one doesn't have
a very high resolution.
If you are concerned about the wing sagging or riding high out at the
ends you should use a long, accurate straight edge and reference off
the table. Better would be two used as winding sticks to see if one
corner is higher.
If your concern is the wing being level with the top right at the seam,
a dial indicator on a base would be an appropriate tool.
G'luck.

if you think you're anal about machinery setup, don't get one of

Hi Silvan,
I set up my new (1 month old) TS to what I
think is almost perfection without picking
up any one of my half-dozen levels.
Don't care much if it's level (as long as the
boards don't slide off!).
It's pretty damn flat tho.

Always turn the level end-for-end to make sure that the level itself
isn't crooked. If it shows up as level one direction, but when you swap
ends shows as not level, then the measurement tool is what is technically
known as "crap".
Do you know anyone with a machinists level?

True. I was just looking to get some idea how obvious the difference is
with a level, because, well, because the idea occurred to me at the time
basically. :)

I'm actually concerned about the wing being machined wrong. It's flush at
the edge, but it seems like the far end is too high, or some of the
surfaces of the waffle pattern were not ground down to the same plane as
the edges. I'm having trouble figuring out which is which. If the wing is
flat all the way around, then maybe the edge of the wing or the edge of the
saw needs touching up or shimming, but if it's a high spot, then I guess I
need to think about grinding it down.

True, but if I could establish the level of the main body of the saw in a
sufficiently precise way, and then compare the level of the wing in a
similarly precise way, I could gauge how much the two planes diverge from
each other. It seems a reasonable enough theory; I just don't have
anything to measure levelness with sufficient precision to produce any
useful information.
I guess I need to come up with a really straight straight edge that doesn't
flex, and some feeler gauges. Neither of which I have, or I would have
done it that way already.

She made an official proclamation that "swim-bo" was back on the job about
two weeks ago, I guess. She gets the rest of the tubes out in two weeks.
She's back at work. Worked part time last week. Back at work full-time as
of today. She's doing pretty well. Getting to gossip with all her
she-buddies about all the juicy gossipy hoosabludgja has done wonders for
her.

sounds to me like you have some bad levels.
first, check the levels against themselves. put a couple of drywall
screws in something immoveable, like the floor. twiddle the heads in
and out while checking with a level until you get it level, then turn
the level end for end and check it again.
some levels can be adjusted, some can't. the ones that can't, and are
out, throw away. if they are also something else useful, like a square
head that *is* square, mark the level as bad.

Assuming you're talking about similar spans on the level, there is the
waterglass option. Broad glass, compare meniscus, go with the level that's
closest.
Of course, in my house, it's flush, not level, that counts in tablesaw
wings. That only requires a straightedge.

Right. If you want to level a machine, use the proper device, a
precision machinist's level such as this Starrett:

Note the wider, shallower vial.

The way you check a level for accuracy is to place it on a fairly level
surface ( level not being critical) and check where the bubble sets. Turn
the level around (180 degrees) and check it again. IF the bubble is in a
different place the level is not accurate.
This happens all the time.

Once verified the levels for accuracy, then cover the top of the TS with
some MDF (cover the whole top) and make sure the TS is level in all
directions. Then take off the MDF and check individual areas, you will find
out where you have just a section out. Adjust and your done.

Why? It was an alignment problem, not a level problem.
I realize that you are a linguist, rather than a logician, but does
the concept of "category error" have any resonance at all?
You are using a verb to solve a noun problem.

I paid about US $40 for the 8" on ebay. used, but perfectly
functional.

Yes, I can imagine.
I keep my eyes peeled but haven't found a decent level at
any garage sales yet. <sigh>

How is SWMBO doing ? I assume that she's home & back

and don't plug up the ends of the pipe. Air has to flow to both ends.

Make a water level. Clear hosepipe, duct tape and a squeeze bottle of
water with a drop of dye in it. Take you 10 minutes, guaranteed
accurate.

Make your own straightedges like I did. See

I agree with Bridger's suggestions. I am going through the same thing.
I made the mistake of buying a new No98 Starrett Machinist's level
(cheap off e*ay) and now I can't find a level that is close to doing
its job - except the Starrett (thanks to UA100). One level has gone to
landfill and my other (reasonably new) Lufkin level I'll probably be
taking back.

A straight edge works great for checking flushness with the main table
If you want to check for level as with respect to gravity, set
ballbearing on the table and see which way it rools

So should the poor boy be deverbed or denounsed?
Don't just point out the problem, supply a solution, please.

I'm with Dave. I don't think it is important for the top to be
'level' to any significant degree. It is much more important that it
be flat and this you can find with a couple of straight edges or
winding sticks as Dave suggested. A single long straight edge,
referenced to a single corner and then moved to all three other
corners will give you a corner to corner check and then sliding the
straightedge along with it perpendicular to the fence will show up any
high or low spots.
