Automated Cells to Drive Gantt Charts

Im am trying to setup a gantt chart for for our production department but am hiving some trouble figuring out how it works. We dont typically use start/end dates but rather work with estimated hours for a project. What ive noticed is that the Gantt chart cant be driven by a calculated cell when dependencies are on. is this correct?

We drive our other charts based on total estimated time to complete a project, say 500 hrs, then assign workers at 8 hours per day shifts and have a column for OT hours we will work on that job.

The formula (Est Hours)/((Assigned Workers * 8)+ OT Hours) gives us an estimated end date. I would like to drive the finish date of the gantt chart with this calculated number while also using dependencies. Is this possible?
