Hi I have a job where the projector keeps shaking. The projector was already there and was hung on a mount that they had. The mount that was there was real flimsy and had a real skinny pole so we swapped the mount out for a sturdier chief mount. The mount is installed straight to the steel rafters, it's a commercial building. We installed a rubber pad between the rafter and the mount as kind of a buffer.

So before the projector would shake when the door was opened or closed but now the projector shakes all the time. It doesn't get worst when the doors open or close but it has a slight vibration to it.

Has anybody had any experience with this. They want me to fix it before the 13th cause they are having a party and wanted to show holloween movies on it.
