 Having 75% of the drive train without direct connection to the transmission would make me a bit queasy, but then again, I'm not Winnovative. - Taylor [more] |

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:
http://www.chiefdelphi.com/forums/sh...ad.php?t=70627 Here's an OK close up of ours: http://www.chiefdelphi.com/media/img...4275b627_l.jpg 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) Last edited by Rich Kressly : 29-04-2009 at 14:06.
