Delta 34-400 Table Saw adjustments

I am in the process of making shaker stlye cabinet doors, and my joints are off ever so slightly. I checked my saw, and it is also off ever so slightly. The miter gauge and saw blade are off a hair, and I believe if I loosen the bolts on the table I should be able to adjust it. My question is the rip fence. Does anyone know how to adjust the fence so that it is square to the table top. I see a sliver of light when I place my square on the table top and the other side on the fence. The manuel I have shows how to adjust it so it is square to the blade, but not the table top.

Others will reply, but there are threads on here & elsewhere that you can search for that outline the alignment procedure for that saw. IIRC, the blade arbor is mounted on a trunnion assembly bolted to the table from underneath. The first step is to ensure that the blade is parallel to the miter gage slots by adjusting the trunnion assembly as necessary. Following that, you adjust the rip fence so that it's parallel to the blade & miter gage slots. Details of this adjustment will depend on the specifics of your rip fence. Lastly, you'll adjust your miter gage to be perpendicular to the blade, fence, & miter gage slots.

I've been through this a few times; it's well worth the time & effort involved.

The biggest problem I had on my 34-444 was when I loosened all 4 of the Trunnion bolts at the same time. I had the thing so screwed up, I would up buying a set of PALS to get the dang thing back aligned. You should leave one of those bolts relatively tight to keep the whole assembly from just want it to pivot one way or the other.

I made a dial indicator jig, I took a measurement of just the arbor with no blade and found it out .003, is this acceptable. With the blade on it goes out to about .008 or a little more (tried multiple blades). I got the miter slot line up with the blade almost perfect, but my cuts are still way off. I noticed that after I tightened all the trunion bolts, I hit the motor with my knee and it moved the blade. I grabbed the moter and moved it back and forth. There is about 1/16 to 1/8 inch play. The trunion assembly does not move, but the arbor and blade are. Any ideas what the problem could be.
