Glad you asked...
I'm not sure if you want to make a usable elevator in your home (in which case you really should hire a professional) or if you want to make a small scale one. You could make a small one for fun or as a learning tool with some plywood, some string and some sort of cardboard box. Here is a science fair project idea on how to build your own elevator: http://www.sciencefairadventure.com/Proj...
Then again, this answer might help you...
You can make an elevator with some plywood, spindles, some cardboard, nails and some other supplies. You will need to set aside about two hours for this project.
