I'd like to build an elevator for my apartment building. My plan is to use rails and grooves to allow the elevator to slide up and down. This means I have to build the elevator with the studs facing forward instead of up. I'd like to have 4 rails on each corner of the elevator and slide them along grooves outside the elevator.
Here's some pictures of what I've built so far:
The problem is that because of the dimensions, I can't quite get the grooves and rails to line up with eachother. How do I calculate a set of dimensions for the elevator that will allow it to attach to 2 pairs of grooves. I supposed I could use just 1 pair of grooves in the middle, but I think that would be less stable.
