It could actually be that your table is perfectly flat if you removed it from the trunion and that the mount may not be perfect. Before you remove the table just loosen the low corner and leave the others tight. Check for square again and see if anything changed.
If you had some way to mount a dial indicator OFF the table but with the probe ON the low corner while you loosen that bolt, you will see that corner rise a little.
You may very well be correct. My "investigating" into the cause of my problem has been reduced to discovering the problem just before I shut down the shop last night, then doing a quick check of things with a dial caliper and straight edge this morning before work. pretty limited at this point.
Like most people I'm sure, I would prefer to be able to fix the problem, instead of having to throw money at it. I'm sure the money for a new table can be spent on some other tool/toy that I cannot live without!!
Shimming helped, but my table has a nice concave shape to it (about .025" low in the center). This of course translates to the fence and causes my fence to be out of perpindicular to the table. With the fence at one side of the table, the fence "leans" one way, and conversely, with the fence at the other side of the table it "leans the other way.
For the time being, I compensated for the problem with shims behind a sacrificial fence. To actually fix it, I'll have to buy a table.
Unless their are any other ideas out there, The only other thing I can figure is to try and sand down the table with an air sander. That would cause the miter slots to be a touch shallower. I'll have to think about that one before I try anything like that.
I am a total NB to the forums... but have had my SS for 16 years. I bought it 2 weeks before I was getting married - I figured that would be the best way to guarantee that my future wife wouldnt say no
Anyhow - I have been working as a materials manager for a machine shop for the last 10 years. After reading your post, the idea came to me about having your table blanchard ground. You can hard mount your table to a piece of heavy steel plate (or the grinding company might do this for you).
Then you could have the table ground to flat.. and it might just be less expensive than replacing it. Just thinking out loud
