Here is our scissor lift test. Our subteams worked very hard to get everything together yesterday, and here is our end product. We couldn’t be happier thus far! My students will continue to modify and adjust problems as they are discovered.
Comments? 
Is it able to remain stable without a person holding it vertical? That is something you may want to work with to make sure your lift doesn’t lean and wobble when you are lifting cubes.
Well they only have 1 side right now, so leaning is kind of expected.
Looks like a great start to your lift! How are you actuating the scissor mechanism, is it vertical rack and pinion gear or something else?
