I think I would start by getting the table off and the mounting hardware off and see what the table looks like loose. I would use a straight edge to sight it, perhaps from several straight and angled views. If it is warped then you will have answered a few questions.

If it appears flat with the above tests then it is likely the mounting that is causing the warp. Not unheard of.

If it can not be repaired, something that could be the case then you still have a few options. I quite like my cast iron table so I personally would try to get a replacement if I could. The newer table is also an option. Then the other option is another used/new bandsaw, ebay or other sources.....

It could be someone here has a cast iron table left over from an upgrade to the AL table?

I plan on getting the table removed. Don't have a grinder but do have a couple of Festool sanders. Maybe the machine shop? JPG is right...my Magswitch fence won't work (I think I have a fix for it). I did lay my Woodpeckers square across it and there is a definite bow starting a couple of inches in from each side. Not sure if the "upgrade" to aluminum fence is worth what SS wants.

A machine shop capable of resurfacing flywheels may be an option.

I vote new table if it looks like that after it is unmounted and the mounting hardware off. At this point it is looking really bad...

It is a fairly significant dish and boy does that make it interesting when trying to resaw.

The last two pix show the 'tie' bar not tightened to bring the front in line with the back. I think the front/back difference will be greatly reduced if that was securely tightened(both screws).

The first is the problem.

You have a flat surface grinder in the disc sander, but this looks too severe for that to be practical.

I got the table off and clamped to my MFT table. It was still dished when I took it off but didn't take much pressure to flatten. The one pic with the bolt not installed was before I got a new one and got it all cinched down. It did not make any difference in the dish of the table. I'll see how this works. Heat wise the best I can do is a hair dryer?

I plan on letting this sit for a few hours and if it doesn't help I will shim up the outside edges slightly and see if I can get it flat with a little more space between the face of the dish and the table. Probably will end up looking lite a pretzel! :D
