Am I correct when I say with a table saw with a left tilt, one would align the blade with the right hand miter slot ? After a significant bit of time and a fair bit of cursing I’ve got mine to less than .001 front to back. If it turns out I’m wrong I’m be really disappointed. Just thought I’d ask those with bigger brains than mine.

I doesn’t matter which miter slot you use because they are supposed to be parallel to each other. If you find it is aligned with one but not the other, one of them is not milled correctly and you should return the saw, assuming it is a new saw. .001 is exceptionally good.

I use the miter gauge in the right slot so that’s the one I went with.

What Lazyman said. Also it generally recommended to have the fence about .002” out (away) in the back to prevent the back of the blade from rubbing. Although if you switch sides very often (most people don’t) that won’t help.

If you can measure +or – .001 reliably I’m impressed.
That’s a very small

Don’t be impressed. I have 2 sets of feeler gauges that go down to .0015, two dial indicators, and a digital caliper.

Are you sure you got the number right ? I’ve never seen a fence that would be flat to 0.002 along the whole length. I also want to see the fence that locks within 0.002 to the slot reliably at any position. That would mean the rails would have to be straight 10 times more accurate than this and no speck of dust on the teflon slides and such.
1/64” is more realistic number

We are talking about set up, alignment of the fence to the miter slot, not daily use. It’s just a common recommendation, not a rule. It could be .004” (thickness of a sheet of paper). Usually the recommendation is have the fence “a few thou” or “several thou” out on the backside of the blade. The point being is to give a smidgen of breathing room at the back of the fence. This isn’t anything new, it’s basic tablesaw setup. If 1/64 works for you then go with that.

To reinforce what TheFridge said, align to the side that you use. I’m right handed, I align to the left slot. I’ve heard and read that you want to stand to one side or the other of the blade. In case there’s kick back; you won’t have your body in line with it.

Just be sure to use the same miter slot for aligning the fence that was used to align the blade.

Right I’m using (or will use) the right handed slot. Just didn’t want to do all that work and then read an article or post that reads something to the effect of you must align your blade to the left side miter slot. I’m just going by my feeler gauge and truthfully I think I just got lucky. I don’t have the skill to repeat these results over and over.

If your miter slots are not strictly parallel return the saw. You would not be able to use it with anything that uses both miter slots at the same time.
So it should not matter from which slot you tune the blade.
