Hello, I’m a bit puzzled,.

I’ve inspected the washers for damage, at rest the blade isn’t warped, from rest the blade stays even, but with even a slight nudge or force, the blade wobbles a ton, see below:

New blade? Old blade?

It has the characteristics of a blade that wasn’t properly tensioned.

Are you sure it is the blade and not somewhere else in the saw? The guard is moving with the blade also, I think it is in the saw mounting. Is it a slider?

Loose nut?

The guard looks still to me.

Looks like the arbor is floating… it will stay straight due to centrifugal force when spinning, but side force moves it. Unplug it and grab hold of the blade – push and pull it to see if you are getting movement in any direction. If you are, then you probably need to open it up and see what is going on… my guess is bearings. How old is the machine and did this just start?

Put the blade on a known flat surface and make sure its not flanged. Also check for missing teeth.

Examine the arbor nut for a keying flat and that it is properly installed.

Make sure the blade is mounted in the correct direction and ther are no gaps on the arbor washers / nuts (use a slip of paper or feeler gauge to check.)

The motor bearings could be shot.

All else fails hit it with a hammer and tell the spouse you need a new one.
