Get a deadblow hammer and 'persuade' the table
back into alignment.
There's few parts that can woggle much
on any bandsaw. My guess is that the table has been
loosened and slid 'downward' under gravity.
If you give it a rap, and it moves - see above.

Do you read my post?Originally Posted by Jim Matthews
It is not the table. The thrust bearings are independent of the table. The blade is too far to the right with the table removed.

That blade is not off center. The guide block is made to be adjusted for inaccuracies in manufacture.
You will notice that the shaft that bearing on is hex. You can adjust where the blade touches the bearing by pulling that shaft out, turning it, and putting it back in.

And if you break a trunion, or both, too bad?
You do not take a hammer, or and sort, to the table. Loosen the trunions and move it by hand.
The problem with this thread is we have issues on 2 separate saws, instead of having 2 threads on 2 saws.

You don't say what make/model your band saw is (I assume Delta, since the OP had a Delta). Anyway, from my limited experience, for most if not all Delta clone types, the shaft that the thrust bearing rides on is eccentric on the end of the shaft that mounts in the bracket (both upper and lower). That larger shaft can be either round or hexagonal in cross section, and can be rotated to adjust the location of the thrust bearing shaft.
Could the mounting shaft have rotated out of position in its bracket hole, such that the thrust bearing has moved laterally out of position relative to the blade? Just a thought.

I've never heard of or seen anything like this, but given that it's further off on the bottom than it is on top, it suggests that something's gone wrong with the bottom wheel. What type of saw do you have? Are there co-planar adjustments on the bottom wheel? Can you post some pictures?

The wheels are coplaner.
Attached are some photos with the table removed.
The blade is tensioned.
The saw is a Delta 28-276

I was actually hoping for some better pictures of that bottom wheel. IMHO, from what you're describing, something's gone wrong in the area of the bottom wheel. Even just looking at the 4th picture, it almost looks like the blade is wrapped around something it shouldn't be wrapped around. Maybe it's the funny camera angle, but if I draw a straight line down, it doesn't appear to come anywhere near the actual wheel. I'll bet you money if you just take your hand, and follow the band up from the bottom wheel to the trunnion, you're going to find your problem.

It's riding on the door clip.
3/4" blade? 1/2" is really the max for these saws.
