Next time, I also wanna know the RPM this monster is spinning the output gear at!

Given what I can see in the video, I can give you an estimate: @ 0:03 looks lke a 2:1 ratio on the big to small gear, 40 teeth on the large gear, 20 on the smaller. @6:17 same gear ratio (2:1) with 20 teeth on large gear, 10 on small. Assuming same gear ratio on all gears, 10 gears, so output gear should be spinning at 2^9 of input. @ 5:22 begins rotation, ends 1/2 rotation @ 5:32, so approx 3 rpm, or .05 rps input. .05 x 2^9 = 25.6 rps, or approx 1,536 rpm.

00:05 That raft removal is extremely satisfying. I don't use rafts often but if mine came off that smooth I might. I'm more of a brim guy. Edit: A video on raft tips could be cool I would use them more if I could dial them in like that but I tend to use other options due to not wanting to deal with the drawbacks.

Have you thought about sticking bearings in the center of the gears ?

What about a 16mm steel rod😂 to prevent it from breaking in the first place

I can't quite tell how hard it is to rotate from the video but I'm curious to see how much voltage it can generate if you attach it to a generator (assuming you would be able to rotate it with the extra resistance force)

@sharadkumarsingh4802

2 жыл бұрын

Lol it already is very difficult to rotate it without any load attached to the last gear, once you add a load to the last gear, it would become almost impossible to rotate it without breaking the axle or gears

@schwuzi

The output voltage would be dependent on the generator. Either way it doesn't matter, as the generator can only put out as much power as is put in at the crank handle. With this much friction in the gearbox and efficiency losses in the generator, you would probably lose over 50% of the energy you put in.

It’s amazing how easy you can take the raft apart! I would love to know your raft settings

I'd love to see you use an online tool service, and make one of these out of metal!

Going to try and post more consistently, it's a ton of work!

it seems that you have to go with the hardened steel way, probably nearest workshop can help you with that I just can't believe that you actually 3D printed that handle bar, I thought it will be just a wooden block

I love your cinematography in these vids it lets us see the trial and error process not an instant success

It is a known problem with 3D printing gearboxes, if you turn the handle fast, the screws in the gears can fly off and possibly hit you in the eye and cause you to lose your eyesight, which would result in the loss of your entire life, and also there would be no more 3D printers." The quest owner decides to take up the quest again, but with much more care. The quest reads "3D Printer Gearbox - Mega Torque Handle Speed Test - Part 1 - Gearboxes and Gears - The Gremlin is back." The quest owner decides to try a different approach. The quest reads "3D Printer Gearbox - Mega Torque Handle Speed Test - Part 2 - Gearboxes and Gears - The Gremlin is back - 2nd Gearbox and 3rd Gearboxes." Again, a thoughtful response comes from the wizard. "Dear Quest owner, Thank you for sending in the parts for me to work on. It has been fun working on the gearbox again, and I am sure your son's eyes will be back to normal. I look forward to seeing the completed product. Best wishes, Wizard". The quest owner decides to try again, this time with some more caution. The quest reads "3D Printer Gearbox - Mega Torque Handle Speed Test - Part 3 - Gearboxes and Gears - The Gremlin is back - Final Gearbox and 4th Gearboxes." A second thoughtful response from the wizard: "Dear Quest owner, I've been busy, but I have some of the parts I need to complete your son's gearbox, which I have kept safely at home. Here are some screenshots of my 3D printer so you can see the size of the pieces I am working on. See you soon! Your Wizard". This is my interpretation of what might have happened in our 3D printing system when I first received the 3D printer for my son.

0:26 you spend so much time trying to get a perfect number on your calipers. I feel attacked, why do we do this to ourselves

It's extremely important to set the calipers to exactly 10.00mm when marking with a sharpie 😆😆😆

That is why i am subscribed

Pretty cool

Tho you have the right idea with the drive connection on the handle and main gear, the shaft itself is too thin and soft for the end resulting torque and force. Also some bearings would help out allot on the high speed gears

This was edited like an episode of legion or stranger things and i love it

You can add a couple more gears so it'll be harder to turn, then put some weight on the lever. It'll pull it consistently for some time and you can make a gravitational electric generator

First ten seconds: What is this an asmr channel?

THE METAL BROKE? i am soooo jealous of the setup. i want to replicate it and make some kind omf mechanical battery with elastic bands to power a centrifucal clutch. that would do the job. What gear ratio did you use there?

Alternate between gears and chains to stop slipping also hardened steel needs to be drilled at the low speed and high pressure that drill press was spinning too fast thus just dulling the drill bit

Can i recomend layout fluid, center drills, and slowing down the rpm of your drill. I feel that would help a little on the metal side. Awesome print by the way

Please turn this into an air raid siren

You should make a gravity fed generator with it. Put a wheight at one end and a generator at the other

Why you don't put the lever up whit the wait stiched to it, whit that you will convert potential gravitational energy to mechanical or even electrical energy (using a generator)

on the gears that always slip change so an inside gripping gear so more teeth are in contact at once for better max torque maybe?

Consider some goggles as you lean over the high speed rotating print.... a shedding tooth might hurt!

You can get little carbide endmills bits from china that are extremely hard but brittle. They're used for cnc cutting circuit boards. They are much harder than the hardened steel but again they're very brittle. The trick to using them is spin them as fast as possible and move them into the material as slow and gently as possible. I like to hang something on the drill press handle so it has a gentle constant downward pressure and then I just let run on its own.

The song was dope

Damn how do you separate that raft so easily?! Is it the material or printer calibration mainly?

oooookay, that was a funny joke with the vernier caliper haha. ha.

here’s a suggestion: you should place it in a tray to allow for oil to lubricate the gears and to prevent the faster gears making a mess you should have it enclosed in a box.

Why would you carefully measure out 10.00 mm only to roughly mark the distance with a fat marker? And then freehand extend the marking and eyeball the leading indentation?!

do u have ratcheting cvt videos?

If you don't care about sacrificing a few drill bits just hang something on the drill press handle to get a constant gentle downward pressure and just let it run. I'll get through eventually but it'll definitely ruin the bit

Try using a keyed rod and gear it leaves the rod stronger.

I was both impressed and terrified, I was worried you'd put something lethal on the other end. Or, well, anything spinning that fast would be lethal..

So when do the neodymium magnets come out and you make a gravity generator

Bro just make pedals it would be easier to push with your legs and then you can add 2 wheels and a chain

Please connect an electric generator to the last Gear, so you can prove how much torque Is needed to produce High rpm and electricity. Maybe you can try with longer bar if Is too hard to push. I think a vertical Gear box attached to the ceiling Is Better, so you can push with arms and legs.

10.0 right on the spot.....and then you use an marker.....😅

0:43 wait a minute, is that a 69..?

What is the point of having such a large lever? all you do is add excessive torque on the system. If the driving force is too great then remove a gear rather then making the lever longer and putting excessive load on the axel. Both achieve the same exact outcome.

Is this enough torque to pull my fat ass?
