Today, another simple and effective design from Paul (Sariel).
From the image and video below we can see how to build a 2-speed orbital gearbox.
As explained on the image, it is a synchronized design, where the gearbox shifts by rotating the blue axle 180 degrees. See more, at Paul's Brickshelf folder like an 'heavy duty' design (below) which internals rotate faster, cause extra load forces but features the same gears relations.

Thank you Fernando, you have, however, forgotten to mention that this is not just an April Fools, this design actually works ;)
LoL,
Sure it works!
Also thought in something for the April Fools, but decided to post nothing like that. ;)
Although if someone gets in doubt, it wouldn't be so difficult to try it by himself. ;D
It reminds me of a mechanism I thought of after building my Grabber I and seeing how awful it performed: to have 4 functions with 3 motors, it used a non-syncronised mechanism like the 956 Auto Chassis and the two next Supercars' gearboxes, which, like Fernando explained on previous blog entries, has the effect of the gear teeth colliding with each other instead of engaging.
However, the difference is that in my design (I never got to actually implement it) the shifter acted only on a limited range, with an output at each side, like a pendulum.
It's a bit late now, but when I have time I shall make a small LDraw render to better explain what I mean. ;)
Look what I've found here! I was just searching on youtube for lego guns, and I came on a site called www.lkmachines.com. There are really cool lego guns, and even a Lego Minigun. And they've even made instructions for their guns!!!
It's awesome...!
lol very inteligent and perfect but it is also good to make a revesing gear box !!! IT'S awesome !!! I am doing the 10 speed manual gear box with high and low from 1 too 10 and lower gears 1-4 / hiegher gears 5-10 I will use it to make the reverse ... thank you very much for this idea !!!
