iam gona do a couple of garage door side rails, on the wall, the 4x16 will be 5/8 plywood with a 1x4 under frame,with a couple of garage door rollers attached to backside to fit in the rails... and ill makes some fold up legs from 2x4 and hinge them on the backside so when its an easel they will be used to stand out the easle...but when the backside of the 4x16 is let down(by boat winch & cable)these will become the table legs........
