3D Printer Gearbox - Spinning it FAST

[Episode 6] This is the fastest 3d printed gearbox that I have ever created. It has a 512:1 gear ratio. How fast can we get it to spin?

Follow along as we 3d print different gearboxes, try different gear ratios, explain the science behind these mechanisms.

Truly an engineer moment when the placement of things doesn’t cross your mind until you have to take what you built apart

[thevideo]

Put some silicone lube on the gears/shaft, or hook em to ball bearings. That'll really knock out some of the friction :)

[rlevy]

The way you made the screw near impossible to reach kind of makes you a real engineer

[loganakboy]

You need a flywheel on the highest Gear so it stops constantly losing momentum every time you stop cranking

[Faris_V]

Nothing like honest clickbait delivering on the common request of "Please just spin it as fast as you can, even if it breaks, that's the point!"

You truly are a gift to this particular YouTube niche.

Infrared camera view of that construction would be fun. Would be interesting to see where the Energy gets lost.

[regeanewolfe]

If you have the appropriate tools, try bending part of the metal shaft to make it into a handle itself rather than depending on some sort of glue to hold a handle in place

[georgel]

Use a square rod with a keyway through the gears as opposed to cylindrical. Then you can drive it with a high torque drill. Lubricate the gears. Put a propeller on the end, brace for takeoff

[adamhancock]

I wish you’d put a contrast color line on each one so that the speed of rotation shows up better on camera.

[AERuffy]

You should add keyways to the gears and use a keyed shaft

[Naif_Vox]

Last gear was spinning 167 times in a second, that's wow!

[IsaacFernatt]

this man just sacrificed a perfectly good table for a youtube video, props to him

[luidelpatron]

Its currently 2 am and im watching this. What am i doing with my life

06:01 What we like to see next? Faster spinning Gears of course!

[jamesstafford]

Can’t believe I watched a man spin a handle

[GadgetAddict]

Very cool. Maybe you should key the handle.

Use a file to put a flat section on the axel and then have that slide through the plastic handle, with a lock pin either side.

How to destroy world: put a 10000 rpm motor in the hand wheel

[kentucky_bandit]

You should start putting a black mark along the gear at even intrevals, either a single line, (center to the outside), or a pie slice colored in, to allow the casual viewer an easier time counting rotations.
