The first thing to work on is the base that houses most of the lift mechanism its construction is quite simple, consisting of two long planks screwed to a set of end pieces, with boards attached to the top and bottom. To keep things square to the inside of this base in the middle, we can mount a motor that will move the platform up and down. The particular motor has a high torque at a relatively low rpm giving it plenty of strength. To raise and lower the platform at a suitable speed, we need a variety of pulleys and wheels. The first one can be fitted onto the motor itself and can be held in place with the included grub screws and a bit of thread lock. Attach the smooth free-running idler pulleys to some large right angle brackets using some nuts and bolts.
