How about using a teflon bearing spinning on a teflon plate?

"shit"🙃

What happens in 04:43

Loved seeing how this is made on the lathe! I assume the watch oil was due to the high speed / weight and trying to reduce friction to help prevent scratching the glass or would you mind explaining? What kind of spin time can you get with that (if any) with just a finger spin? Love my CapoteW2 in tungsten.

Just awesome. The time you saved me from having to go through this myself is appreciated 😀 Step 1 ... buy a lathe.

is tungten steel? how the common drill and knives can cut it?😍

If you reduced the diameter of the spindle a little you’d probably get more revs out of it.

Does the watch oil help it stabilize faster, if not what does it help with? If it does help stabilize faster, would it make spins longer or improve stability on your Orbit Top?

Mt-185 is 97% Wolfram 2.1% Nickel and 0.9% Iron!!

Great vid. Mesmerising to watch metal machining. Thanks 👍

It's a 33 min spinning top, phenomenal. Never knew such things existed.

Awesome video! Loved the press ruby tip, but for some reason expected it to be spinning on granite, is that a thing in the top world?

the performance improves dramatically...take your thumb up..

It would be neat to monitor the speed with an IR tach (would need sharpie marks or something), and monitor the bottom of the plate (maybe paint it black) with a thermal camera to watch for heating from friction (probably negligible but would be cool to see if possible).

(I found it in the trash) was my favorite part. Edit - I lied, sleepy orange baby at the end is best part.

Now shoot some electrons at it

Look you were going to get a like but the moment I seen your cat lol

Very cool.

I believe that part of the stability problem is that tungsten is harder than glass and the top tries to dig into the glass. I suggest using a composite top with tungsten peripheral and a mild steel as he pivot point.

What's that you're sprinkling on it? Looks like grated Parmesan cheese!

Absolutely beautiful!!!! Thank you for making this video. How much can I buy one like that?

Very Beautiful! Have you considered making a top with spokes to reduce the amount of friction between it and the air?

Just placed an order for one of these! Can't wait to receive it! I keep a series of Plier Spinning Tops on my desk at the office and every visitor I have asks about them and wants to spin them. Such a great conversation starter!

You could add a squiggly line on the side and or inside if you wanted there to be a way to visually tell how fast it's spinning, but the mystical look it has when it's as if it's not moving and just floating would be lost so

Impressive skill & talent, Chase, not that's anything new to knowing about you. For a Big Ass Top, it looks terrific!

This has reminded me of those large spinning-mass Uninterruptible Power Supplies ("Dynamic UPS", "Rotary UPS", "Flywheel UPS") which are available, which have a large spinning mass inside a vacuum, which floats on magnetic bearings to minimise drag even more. Power input and output is electromagnetic and they only provide on the order of minutes of power after a power outage, but they are intended merely to cover power for the time it takes diesel generators to start up and take over the long term power delivery, until the power outage is over.

2:30 Sir, you didn't give us the cat's weight, dimensions, or composition. 1 demerit.

So this is how we can build the ultimate Phantom Orion.

This guy stole my idea for a video. Glad I did not start making it yet.

4:40 how can that break the sound barrier? The sound barrier is at 333 m/s. at 30000 RPM the top spins at 500/s. That means in order to break the sound barrier the circumference has to be 66 cm so the top needs to be 20 cm in diameter. That makes no sense so it should be another effect that causes this phenomenon?

Nice milling! Not sure if any prototype CNC may help for upcoming content? If so, would love to sponsor and do something together! (PCBWay zoey)

Thanks for the trip down memory lane. In high school electronics my friend and I built a magnetically levitated pentagonal mirror that we could then spin like the rotor of a motor (based on toy maglev globes but way souped up and a mirror from a photocopier) We had access to an industrial vacuum chamber and from about 100k rpm it spun for hours! Eddy current losses in the suspension magnets were really the only energy loss. Also (outside the vacuum) had fun bouncing a laser off a mirror taped to a speaker and then the spinning mirror to make scan patterns of music on the wall...It was an amazing project I'm sorry we didn't document it better.

the sonic boom at 4:40 😲😲

"OH come on!" I know that feel...

"Oh, come on!" 🤣

Ever considered making a gyro with magnetic bearings? Zero friction would mean you would not even have the axis touching anything. Make it small, and spin it up with air from a small air line. I’m talking SMALL, as in relation to your little top. About the only thing you would need to do is machine some very tiny cups in the perimeter of the disc. Once this is accomplished, the top should spin for many hours in a vacuum!

CAT

Experiments are hard. Great work. I would have put the little ring around the spinning top vs chasing it all the time. Or, in teh bowl, as you did for the vacuum test.

Was really worried for you when that Meou-sha inspector showed up on your worksite.

Spin the cat with Dremel in a vacuum

That was a super cool video. I know that air resistance plays a huge factor. But I didn't think it would affect the top so much it being such a small and smooth object.

Machining Aluminum: 😃 Machining Steel: 😃 Machining Tungsten: 💀

There's a type of ultra high vacuum pressure sensor that is essentially a floating, spinning sphere. The energy it takes to keep it at a constant RPM is correlated with pressure.

I'm wondering if the top could run longer if it was hanging from a magnet? Iacopos video mentions that increased weight on the tip can drastically increase friction, and i believe that should negate that problem. Also, project farm did a video on motorkote, which drastically reduces friction, but im not sure an oil would be ok in a vacuum 🤔🤔

Remove this spinning thing, bring back "cat".

Spinning a aluminum flywheel will become superconductive at super high rpms🎉

Use an air compressor to spin the top. Use a metal ball on the top and a magnet to hold it up. Blow the air on the rim to spin it. I didn't know anyone else did this beside me hahaha. I even have the same mirror. I have concave lenses from a projection tv I use too. Silicone on the mirror doesn't seem to help, makes it worse infact. A little bit of friction is required to keep it upright. A small amount of ash smeared on the glass seems to work well.

Cool video, kinda shocked how much better it did under vacuum. This is the reason guys put vacuum pumps on race engines. If you can pull 20 inches or more on the crankcase of an engine turning 8 grand , it really reduces drag inside the engine.

Did anybody see the mini sonic boom on the mirror?😮
