Tank turret using motor or CFrames to follow mouse cursor?

So i've been dying to make a turret that one part turns like a turn table(horizontal movement) and another turns up and down(elevation and depression). However ive tried possibly everything but nothing worked out. I tried creating a tool and getting the mouse.Hit.Position into where the part must point but im forced to also change its cframe and even though i set its cframe to itself, it moves a tiny bit and its annoying because it wont allow you to directly change the lookvector.
