Re: pic: 1712 version of JVN high reduction gearbox
We just followed from the original JVN picture and eyeballed it, selecting materials from what spare VEX part we had. JVN's version is much more compact than ours:

Here's an OK close up of ours:

most browsers will enable you to magnify the image, or just save it and magnify with software

Essentially, you just need to build a 12 stage reduction using:
4 VEX plates or chassis rails with appropriate width and length
12 12-tooth gears
12 60-tooth gears
1 big wheel on input side
1 small wheel on output side
stand-offs
shaft collars
fasteners
spacers
shaft to size (only one shaft runs all the way through the gearbox - the one at the bottom)
