so, i just got a delta contractor saw, one of the semi-older ones with the beisemeyer and the metal wing on one side, and the wood one on the other. anyways, i started it up, and the whole back of the damn thing wobbles like, really really hard. all six legs are in contact with the cement floor beneath it, and it ran smooth when i had the guy who sold it to me run it. i don’t really know much about what to do. i didnt put it together, i dont have the manual. the belt seems like its in great condition actually, and all the nuts are locked down tight. any suggestions? do i just need to re-align the motor or something? it like, reeeeeeeealy wobbles.

Check the belt not only at the motor but at the arbor as well. If you loaded it upside down they will sometimes slip off yet still rub the sheave enough to spin the blade but you would probabley smell it burning in short order.

You have something going on for sure. If its jumping that wildly now and wasnt earlier , should be a quick find.
Good luck with it !

Have you checked pulley alignment?
Have you changed the blade from 0° to 45° and back?

there is only the one belt, its a contractor saw, the kind that the weight of the motor holds the tension. my first thought was that the angle of the motor was out of wack, i managed to make it worse, then return to just as bad as i thought it was. how do you know what is correct? is there some kind of reference? i would like to put up some pics, maybe a video. I’ve looked, but noone seems to have my particular problem on google or youtube. any of you guys set up one from the box? how to do you first align the motor? or the pulley? or whatever? thanks all youse guys that have replied, this forum is really really good.

and i did try to change the angle, not all the way to 45, but i did try to change it, didn’t have a positive effect.

Just a small suggestion. You say that all legs are touching the cement but is the table level? If you are on an uneven surface, you might want to extend or retract the legs accordingly until the saw is level. An uneven table might be enough to throw everything off.

it ran smooth when i had the guy who sold it to me run it.

How long ago was that? Sometimes if the belt gets old it will get stiff and cause excessive vibration, you can replace it with a link belt. Does it rock at all while off?
