Topic tags/keywords: question tablesaw machine setup alignment calibration extension tables

I took delivery of a new Grizzly G1023RL tablesaw late last week and have been slowly cleaning it up and assembling it. I used a precision straight edge to line up the cast iron table extensions, but it seems no matter how much I fiddle with it, I can’t get them completely, perfectly flush with the main table. The best fit allows a very thin piece of paper to slip between the straight edge and parts of the tables—some parts are perfectly flush, but others aren’t. This obviously means the tables are not perfectly flat. So my question is, how close is close enough? Should I expect total perfect flush alignment of both wings along their entire length? Or is a little imperfection no greater than the thickness of a thin piece of paper here and there OK?

This is my first experience with a “good” tablesaw, so I really don’t know what to expect.

Your side tables might be flat and the problem is where they bolt to the main table. If everything were dead-nuts flat on top, but the edges were slightly off of 90*, you would see this problem. Nothing is ever perfectly flat or square so it’s up to you to decide if you can live with a slight mismatch. Remember that you’re a woodworker – not a tool and die machinest. – lol

When I set up a table, I use a long straightedge to bring the outer edge of the side tables up to the level of the main table. If the inner edge is high, I make it even and let the outer edge be a tad bit low.

I think you will be fine. I have the exact same saw and mine isn’t perfect either.

There is no way that much of an offset could really effect your work. I say enjoy your new say! It is a “good” one for sure!

If I’m reading this correctly, you’re worrying about .004-.01” of height difference. I’m thinking you’re going to be fine if that’s true.

Where are you high and low? That could determine what to do next.

Otherwise, how much money and time do you have? Someone could get it closer if you have lots of both.

The proof is in the pudding. If the saw cuts well, you’re good to go….which I suspect will be the case. Blade selection and blade alignment are the areas to get picky about, but it’d take a pretty sizable deviation in just the right spot for table flatness to effect anything.

I think you’re OK. I’m sure the extensions are far flatter than the wood you’ll be cutting.

my router wing sits about .002 below the main saw table, works fine and has not affected precision.

I would think that you don’t want the extensions extending above the saw table itself (they probably pay most attention to that at the factory). Other than that, you’ll be fine.

Thanks everyone for your input. Since I never had any experience with a cabinet saw before, I didn’t know what to expect—had no idea that anything less than absolute perfect flatness was acceptable.
