I have a ram mount x mount for my tablet on a small arm. It won't tighten. Even after cranking on the mount bracket, the tablet mount still rotates over bumps. Any ideas? is there something in the X mount that needs tightening?

Not only are RAM mount components sized for a particular ball diameter, the ball diameters correlate to a weight rating. If you've got 3 lbs hanging off the end of an A- or B-sized ball, for example, it will probably slip. (Don't forget to factor in the weight of any arms, etc. you've got hanging off the problem ball.)
Ram mounting balls come in 4 sizes. To hold something with as much leverage as a tablet you'll need at least a 1-1/2" ball or larger. If you are using the 1" ball mount, the smallest size, that is adequate only for a small GPS unit or phone.
