    @@ZeldaIsMyLove If the flywheel takes 0.5Nm to move, it would take 256Nm on the input shaft to move it. If the crank is 7cm, that's 3657N of force required at the end. That's 373KG of force on that 7cm crank, to get just 0.5Nm on the output shaft. Moving the flywheel first would work, but if it slows down even a little, it would be extremely hard to add energy back into the flywheel.

    @TheRealLoganYT Kind of like how older axes are done so the handle can hold the axe head without worrying about the axe head flying off. If you look up videos of people making their own axe handles you'll probably see an example. Lots of machinery use keys in places where they have rods/axles as well (though positioned differently) because the key becomes the shear bolt so if anything is going to break, it's going to be the key instead of all the expensive stuff. The kind of things engineers have come up is pretty darn neat, god bless 'em

    Some ideas from an engineering dropout, rather than substantially thinner gears on the faster end, decrease the infill on the print, you're losing efficiency from the thin plastic flexing as it spins fast. Some combination via trial and error may be needed. You're never going to get adhesive bond to an axle to hold the kind of mechanical advantage you're working with on the handle, it's surprisingly easy to key a shaft with a dremel and then use a dab of jb weld to secure the key. Lastly, bearings might seem like cheating but you should definitely have something there. Might I suggest brass bushings and a bit of lubrication? They can work a dream and aren't too difficult to make.

  • @rajinkajin7293

    @rajinkajin7293

    Golf ball pips would probably not help in this application. Hear me out. Golf ball pips do increase the range of golf balls by decreasing NET drag, but there are two different sources of drag at play. First, we have "frictional" drag, where the air that is stopped rubs against the air that is stuck to the surface of the object. Second, we have pressure drag. I'm terrible at explanation, but imagine a bullet traveling through water. If the bullet was traveling fast enough, as water has momentum, it would "jump" off the nose, and then come crashing back down together. The void that is created is very low pressure, and literally sucks on the bullet, slowing it down. Golf ball pips INCREASE frictional drag, but this energy goes into creating turbulence that extends the boundary layer, or the area around the ball where relative air velocity transitions from matching the ball to stationary. This causes a lower tendency to suffer from flow separation, and thus decreases parasitic drag. The same effect could be achieved by having a teardrop shape, like hypermile cars, but balls must remain rotationally symmetric. A gear has a constant cross section when rotating, save for the teeth, so I believe pips would only increase drag.

    The spokes in those last gears might make them lighter, but it's also going to add drag. A solid gear with less infill will the job done better.. It'll probably help keep the fastest gears better in-circle as well. The last several gears would benefit in being balanced. The vibration and wobbling adds a ton of drag and is causing most of the plateau you are hitting. Reducing tolerances between the gears and shaft would help with that as well (+1 on the idea for quality ceramic ball bearings). With those tiny changes, I bet you could go a lot faster, and probably with much less force.

    Would be cool for you to get a digital tachometer, to compare the calculated gear speed vs actual. If the prints are good the calculations are probably accurate, but would still be a great video aid to see the numbers digitally!!
