Hello again, im not sure if i can paint a good picture of what im looking for, but ill give it a try. I am in the process of making a fiberglass console, I have created a recessed panel for the radio and video monitor, but i would like to cover it with smoked plexi glass. Now here is the question, i would like the plexi to slide up and down with the flip of a switch, exposing and hiding the radio. Any thoughts as to what i should use to operate this motion would be greatly appreciated. (didnt want to go the small actuater route). The glass must slide approx 9 inches up and down. Thanks in advance for any help, im drawing a blank on this one.
