This is not only an awesome aesthetic build but an amazing mechanical build as well. A beautiful synthesis between form and function. You persisted and never sacrificed your vision from the gears to even the bracket colors on the shell. Your problem solving is inspiring.
As a fellow gear enjoyer... Start with your gear setup, add a second gear to the "driven" side. Spread the 2 gears out just a little bit, and you wont have the "skipping" or "dipping" issue anymore because at least one of the gears is always making good contact due to the space between them
Add a second gear to the side with one and put some space between them. This ensures that at least one gear is always making solid contact with one of the four gears thus preventing the issue. Hopefully that simplifies it enough
You went from making a gearbox to making a slip-joint axle. You should take a look at some automotive diagrams sometime. You might learn some building techniques that could come in real handy. Especially if you want things to turn and move at the same time

I love the solutions Lego engineers (amateur and professional) come up with. Lego really is an incredible tool for teaching creative thinking, and problem solving.
There is an 8-tooth gear without friction, so it doesn’t grip the axle. You can trap it between two beams so its axle can move while it can engage with another gear on an unmoving axle. This is about a third of the size of your current solution and no jiggle!
@ Are you talking about the old z8 (part 3647) or the new one (10928/11955) with reinforced teeth? The new one was released in 2006 but they still put the old one in sets until 2016 for some reason. They are basically disposable. I’ve never had a new one break on me.
The solution you used was very good, but if you’re still interested in learning about other options, I’d recommend taking a look at element # 11955. It’s a similar element to the classic technic 8-tooth gear, but with no friction, so it can slide lengthwise along an axle while still being able to transfer its rotation to other gears.
The side of the axle that moves the flippers is fixed to the platform the turtle is on, while the side powered by the motor can move freely. The wormgear is held in place by bricks, so the worm gear stays in place while the axle slips.
The issue is sort of the gears. This is why we have bushings and bearings and cam profiles, which is what you did there. Made a much more advanced gearbox. Before it was straight cut gears on a long shaft. Not really great for high RPM and low vibration. With the cams, differential setup it takes some of those vibrational loads due to the changes in direction. Is what I think is going on. I don’t know nothing man
@@oofman1911it has nothing to do with applying something smart and has everything to do with the dislike of the gears being because of the turtle head jiggling
Everyone keeps saying that. I think worm gears result in a ratio that actually makes things more complicated, even though it does allow the axle to slip along it
I mean those aren't really regular gears Lego calls those bevel gears for a reason. people just seem to think that they're regular gears because they came in all the Bionicle sets before the Inika build became standard

The gears would have needed a synco-mesh so the teeth mesh together perfectly. The jiggle was the gears not meshing properly. Your solution was the most compact and efficient solution
Those gears will always have a soft spot in my heart because of bionicles. I remember putting together Kopaka and having him swing his sword and shield.

Or either you could use sliding red 8-tooth gear. They are not common on sets, but can be easily finded on bricklink
True! Those small gears tend to degrage quickly though!
There is an 8-tooth gear without friction, so it doesn’t grip the axle. You can trap it between two beams so its axle can move while it can engage with another gear on an unmoving axle. This is about a third of the size of your current solution and no jiggle!
I sadly didn't know those existed! I am worried about the long term durability of that though - I have had many of those 8 teeth gears wear out on me.

Why didn't you use the spiral gears? Lego specifically makes these for this type of motions
Don't know what spiral gears you are thinking of, but worm gears mess the timing up and require several gear ratios to correct it.

In the set 42009 are red gears, which can slide on axles. These would solve the problem even more elegant.
