This may have been done before but I havnt seen anything on youtube so I decided to design my own and publish it here so others didnt have to.

This IS Infinitely expandable! I dont have recording software so sadly I cant make a tutorial. 

WARNING! This design (So I believe) Needs to point WEST for it to work (There will be an arrow ingame that will make it a bit more clear) it may be able to work in other directions but in my experience it shouldnt, simply because the way tracks work and how they default. (Redstone input defaults to specific directions)

The build is very strict with ceiling hight, so each level MUST have 3 blocks of space between eachother! (or 6, 9, 12, ect...)

Im still working on making it more compact and adding more options for your ceiling  hight, so its not as annoying to add it to
pre-existing building that did not have a dumbwaiter in mind. thus making it 90% done


Hope you like it!
