I'm not quite sure I understand exactly how this would work with spinning metal gears and the such. I understand that this is designed to be able to shift on the fly.
However, I dont understand how the gears are supposed to be meshing. From the way it looks, the two main drive gears are always spinning, and they continue to spin as the main shaft shifts over. Now from what I've learned, as well as from first-hand experience, "shoving" a spinning gear into a non-spinning gear can't be healthy. Sure, it will eventually mesh together and start to drive -- but what is happening in that time before they mesh? I, personally would not want to trust something like this b/c I would be afraid of gear teeth breaking.
Is this how 45's gearbox works? I'm not really sure... I looked at it VERY briefly LATE last night while I was falling asleep, and I just couldn't figure out how that shifts. If that is the case, I would like to find out how those gears held up to grinding and/or breaking teeth...
