Easel Construction

This is a picture of the back of the shelf, the heavy steel plates on the left and right fit into the cut grove in the side of the easel. This will guide the shelf up and down the easel. While the knobs toward the center will draw in angled steel pieces which will act as a brake locking the shelf into position. Considering the heavy weight of the shelf I can see I’m going to need a counter weight system or a marine crank system to make adjusting the shelf and easy task.
