This is incredible... After half an hour of looking at ABS-111 (the latest one I can find online) and googling planetary gear ratios, I think I sort of understand now. Time for questions:

• which one is the carrier plate?
• how do you lock the ring gear/carrier plate? I'm assuming there's a custom piece of metal the render is hiding... I want to see it.
• checking my understanding: so there is a "suicide mode" (high gear/PTO) where the carrier plate is linked to the input but the carrier plate is locked?
• consider using Andymark's new CIMcoder? I hear that it's thinner than the 3D printed one
• how does one machine their own ballshifter? (looking at ABS-111)
• Is that 60t gear hitting the bolt next to it?
• how close are the CIM gears to hitting the gearbox plate?
• that's a cool way to attach something normal to a gearbox. I might steal one one day.
• what are those 6 holes near the output for? I assume 2 is for mounting a piston on the other side, but 6?

Doing this would not only move the shifter out of the obvious place, but it would be difficult to pass all the different coaxial shafts through the large gear, so I'm guessing that the annular gear has teeth on both the inside and outside of the annulus, and the PTO is another spur gear that takes off of that. Doing bevels would require a lot of extra work and thrust bearings for no discernible benefit.[*]If I understand this right, the PTO output would have to have the shifter in high speed/low torque (single stage) mode, and the carrier is locked, so the output gear ratio would be (64 / 11) * (72 / 30) = 14.0:1 at the ring gear, possibly higher or lower if the PTO is not directly taken from the ring gear.[/list]

I think the PTO is the front-most gear we can see, and it's connected to the gear on the left, which would mean that the PTO shaft is to the left of the 2nd pancake piston. Looking at the 2 PTO gears it actually look like there is some sort of reverse-reduction there. This is all conjecture though, until we get more renders/CAD.

Edit: can we at least get a render of the internals?
