I cannot figure out how to make the gondola be level with the drawing board. I have tilted the board at an angle, but the problem remains unless I greatly exaggerate the tilt. The only issue I can think of that might cause this is either the weight of the gondola (which should be fine), or the fact that the glue used to fasten the brackets is too thick. The thickness of the glue has caused the bracket hinges to not reach all the way in, but only causes roughly a .35 mm differential. I don't think this should cause it.

Are there any ways to troubleshoot this? My counterweight are water bottles.
