- Second stage uses 1x2 1/8th wall C stock
- First stage uses bearings in bearing blocks designed to be shimmed out in order to get a precise fit to control front to back motion and the side to side motion is controlled by Delrin slides riveted to the top of the towers and bottom of the first stage.
- The second Stage slides are milled Delrin inserts. These can be milled and sanded until they slides cleanly in a test piece of C channel.
- All of the gusset plates are .050 Aluminum sheet with 3/16 Rivets
- Top black brace is made of 1/4in plywood.
- Since this is a mock up the tower is not adequately braced, but for now im interested in critique of overall design.

I am still learning the design of the elevator system myself, but I think you need, built onto the top of that second stage, a mount for a pulley which will route the steel cable (or other means of wire) throughout your assembly. Also, that black plate in the back is going to be secured to the cable, so make sure that it is adequately strong, as it is going to be taking a lot of force.
