How fast can this gearbox spin?

I would recommend using bearings on each wheel and decrease significantly the gaps between the different gears (Use teflon rings)

6:34 That sounded more like a giant diesel engine just starting and revving to warm up.

2:39 Love the physics-ignoring transition

Ever heard of...spacers ? They, when lubricated, can make a more stable machine and make it easier to turn.

Some suggestions: 1. use spacers on the axle, so the gears are fixed on there to prevent wobbling and gears grinding against each other 2. use a normal M8 steel bolt instead of the aluminum rod and screw it far enough in, so you dont get vibrations in the gears. That way, the gears wont come loose as well 3. use ball bearings on the housing AND the gears 4. reduce the contact area of the higher gears. So 1st gear has the most contact area and so on 5. lube the gears and bearings 6. print the grip sideways. so it doeant brake (obvsly) 7 maybe try different gear geometries. there a some that are better for high torque or high speed. the latter have much less drag. 8. you can safe an enourmous amount of weight on the last gears. make them much thinner then they are now

Sounds like straight cut gears ⚙️ they were spinning FAST!

I like it when it spins fast That's the best part

I was not ready for, but appreciated, the ASMR @ 5:11

This is awesome, i love gears and their mechanics so much that i even thought of making a GOOGOL spin with some fictional/indestructible materials and a huge engine, with a big fan on the fastest gear

I really enjoy it and laugh at the same especially during the breakage, oh boy you don’t have any idea how envy I am for such skill you have, keep doing more video, I’m your subscriber now.

Can't wait to see the next iteration, I want this baby to be clocking at near light speed when you are done with this

5:12 Now That is ASMR

I'm surprised that the last gear held together at that speed. Most of my prints seem to break as soon as hit with even moderate violence.

I've just watched for the first time. The first thing that came to mind was, "Wow, he could make a wonderful siren!" I sure would love to have you take me up on my suggestion. Not sure how your neighbors will feel about it though 🤯

Wow. This guy's patience knows no bounds. My patience knows almost no existence.

It’s so satisfying

Well done bro you should be really proud of yourself

I'd love to have a fan blade connected at the end. Would make an excellent hand cranked fan

You are just like me, whenever i do any work after doing all the work i remember i missed a small thing or made a small mistake because of which i have to do all the work again.

How many hours you need until you finished your project
