I have commented about quite a few similar suggestions so I think I'll leave this post here in case your great mind is thinking alike! 1) Golf Ball Dimples / Shark-Skin or otherwise textured coatings for reduction of air drag: Golf balls work by increasing viscous drag but decreasing pressure drag by more (put very simply here, many good vids out there). Since my tops don't experience pressure drag, adding texture would only increase viscous drag. So far, I've found that a perfectly polished surface is best, however it is certainly an area for innovation so do leave other ideas! 2) Ruby/Sapphire jewel tips/bases: Tungsten carbide, like I use, is harder! And easier to get in a spiked form which benefits more from lubrication. 3) Polycrystaline Diamond/Cubic Boron Nitride tips/bases: These are harder, but very abrasive. If only used for the tip, it would cause drilling. If only used for the base, it would rapidly blunten the tip. If used for both ... I'll admit I haven't tried yet but I suspect both would occur. 4) Uranium/Osmium/Platinum etc flywheel: (Apart from uranium) I would LOVE this, however I am not a millionaire so this is completely out of my price range. Pure tungsten would be the densest viable option (almost 20g/cm^3) however I have struggled to machine it in the past. Hence, Mk.22 used a 90-10 alloy (16.75 g/cm^3) which is softer.

@@hiper_tops Does the base have to be static? The base could be another spinning element (with a means to retract when it loses momentum, a centrifugal clutch mechanism or something). That way tip friction could be reduced. The base element could have a shell around the top's doughnut (to shield it from drag). The thinking is to have something like multistage rocket, but with like mechanical parts acting as boundary layer separators to reduce the delta V to the surroundings.

@@phiro4305 The contact point is definitely an area for innovation. I (and others) have found that hardness certainly isn't the only factor - cubic boron nitride and polycrystalline diamond for example are highly abrasive. A carbide spiked tip spinning on either can become blunt over the course of a single spin, causing imbalance, more friction and worse performance. If we swapped the base and tip materials, now the spinning top would drill into the base, get stuck in the hole causing vibrations and losses. Also, yes, coeficient of friction when dry (for ball tips) or oiled (for spike/micro-ball tips) is important! The typical solution is to use materials of similar, high hardness for the tip and base. HSS on WCarbide is good for longevity but for a single spin, WCarbide on WCarbide is the best. Interestingly, perhaps due to Mk.22's incredible spin time, I have found that over a single spin WCarbide on WCarbide can cause drilling and vibrations - you will see this in the full spin video. In my testing it has seemed quite consistent that after about 45-50 minutes, some vibrations occur (not due to imbalance but getting stuck in a hole as described above). If you have any suggestions, do give them (regardless of if you are an engineer or not! I am still a student) :) @xzorby for example suggested a DLC coating on the tip which I am now looking into!

James, I think I saw an old video of your some years ago but happened across this one today. Unbelieveable! Truly a High-performance spinning top. A few points / questions: 1) Please fix your CAD! I saw you had made it in a public Onshape document so I had a look, and you're making life so difficult for youself. a. Model the whole top in a single part studio! There's no need to create a seperate document for every part. Think of documents as binders which hold everything related to something. They can have parts, assemblies, drawings, etc inside. It will make your life so much easier modifying the design and keeping interfaces working between parts. b. Some of your parts aren't fully defined (blue vs black sketch segments) which may cause you headaches down the line if you accidentally adjust something and attempt to make it again. c. Your assembly is floating in space, and has no relation to the origin. Move the point of the tip to the origin, and then aling everything about the Z axis. Then when you measure CoG of the assembly its coordinates will be in relation to the point of the tip. d. I couldn't help myself and re-modelled the Mk.23 shown in the video. If you go to Onshape > Public Documents and search for "James Goh - MK.23 Clean" You should find it. 2) I noticed in your CAD that the brass appears to be an interference fit, if so, how do you ensure that it bottoms out or at least gets extremely close, as if it doesn't bottom out correctly you'll raise the CoG up inadvertently. 3) As others have said, I would watch the hell out of a multi-part, multi-hour detailing of the math and design you've put into the iterations. It's truly remarkable.
@hiper_tops7 ай бұрын
Thank you for these notes! My CAD skills definitely need work haha - I'm more used to solid works but working on a mac at the moment. I found your document - thank you! Regarding 2), I believe that may be an error as the tapered tip holder uses a friction fit. And for 3) I am working on something along these lines but it may take a while as I am back at uni now.

This is amazing! To me this is the ultimate in the "unlimited" class of tops, essentially doing anything you want with the geometry. However, I feel a little bit of the essence of the classic top is lost by allowing a recessed tip and elevated stand--as that essentially removes the part that makes most tops fall over: the precession from CG being above the tip, and the effect of the sides of the top contacting the ground if your spin technique isn't perfect. Therefore as a follow on I think it would be cool to see your optimization of the design under a "legacy" class where it has to run on a flat surface (no recessed tip, or cupped holder). I wonder how the design would change.. because you still would want to get the CG as low as possible, but if too low, the sides would contact the ground too easily. So it's a different optimization. Anyway, as an engineer this is where my mind goes. Good work.
@hiper_tops8 ай бұрын

High performance! For aerodynamics it would be really cool to see smoke stream testing on this. I think the geometry of the base may actually be pretty significant. For the top itself, maybe a blade around the center of the top better direct the top and bottom air flows as they come together? On the friction side of things it may be worth going back to a dual material or hollow design. It would complicate your analysis there, but it may be worth it to bring mass down without affecting inertia too much

Also, I have question: I'm curious, would a dimpled pattern, akin to a golf ball, make for a more efficient grip? In the case of the golf ball, this helps to keep the flow of air more tightly bound to the ball, so there's a smaller pocket of low pressure behind it, but in the case of a rotating object, I don't know if the dimples would be of any use, or if it would make drag worse due to the turbulence. I suppose you may have already considered this, given the number of iterations. I'm interested to hear your thoughts on it.

So this is the only video I’ve seen of this series so I have not learned all that you have in this process and I do not know what rules you have for yourself or what the hp-top community has, but the first things that come to mind without changing the top/base itself is just changes to the overall system: eliminating drag altogether via vacuum, and; changing the temperature of the system (i hypothesize decreasing the Temperature of the top and the base would work best). As for the top itself, (again I’ve not experimented and learned for 7 years like you have), there’s a new material in the making - carbon nitride - and I think it boasts some decent potential as a tip/base material, should be between cubic boron nitride and diamond in hardness, some say it surpasses diamond in some areas, I think compressive strength. idk it’s lattice structure tho I think there’s a handful they’re trying. It’ll probably be an expensive material to experiment with but maybe in junction with a diamond tip/base or a a cubic BN tip/base it’ll fair well. I also don’t know your lubrication methods/results but a low viscosity lubricant may fair well, but it’ll have some form of drag on the system, but by making a thinner tip for the spinner you may be able to reduce frictional drag from the lubricant, but that’s probably diminishing returns. I can imagine there’s some effect that can be taken advantage of my mind kinda goes to magnetism or superconductors but I feel like those would be somewhat cheating/violating the “rules.” Maybe somewhere in the universe there’s a non-Newtonian lubricant with the ideal properties for a lubricant. The only other suggestions I could make design wise would be along the lines of reducing surface area near the center of the spinning area (the big flat disc shaped area) to be 2+ aerodynamic rods connecting the tip and handle to the outer ring. There’s a handful of other experimentals id do but I’m about to pass out and I’m partially regretting going to college for business seeing as I love this stuff so much.

It's a cool idea but unfortunately not! Golf ball dimples help by increasing viscous (skin friction) drag but decreasing pressure drag (by more!). Since spinning tops don't experience pressure drag and only viscous drag, dimples would be counter productive. You may find this video interesting: kzbin.info/www/bejne/nZCvhX2KlrSredU&ab_channel=BilletSPIN Note the best top has internal dimples, however the change in airflow in this region is unlikely to be the helping factor; but rather light-weighting to reduce tip friction.

"shark-skin" surface, less drag 3. "close" the bottom to a certain diameter with a thin disc, skirt, to prevent to much airflow (vortex) underneath 4. make sure there is no induction created from the combined materials just some ideas and thoghts...idk if practical and useful for this physical artwork. keep it going, spin your head round (baby) round round.... greetings from Switzerland

High performance! The fact you have made it past the one hour mark is amazing! So many factors that keep a top/gyroscope spinning is due to friction from the air and the tip and being able to reduce them to the lowest point is already evident in this video. The tip of the point is the only thing that can ruin the longest run, and the hardest materials need to be a small, but round element, in order to keep the drilling of a hole that ruins the anvil for the tip. And the support for the round tip needs to be able to conduct heat away from the tip to keep the tip from galling. Silver and copper are number 2 and 3 in heat conduction, with diamond being number one, which is also the hardest! So a diamond ball, set into a silver mount, would be the best for conducting any heat from the tip, and having it ride on a carbon nitride anvil, which is actually tougher than diamond, could be the best for long duration attempts!

A suggestion: You can add some permanent magnet to counteract weight. You cannot do levitation with magnets but you can lower force on the pointy tip and therefore lower friction. But rotating metal next to a magnet will lose energy thanks to eddy currents, so you will need to use something nonconductive.

Just fascinating! I have had a desire to make a long spin top for so long, yet I didn’t know of your channel. perhaps when my workshop is finished I can make something that will spin for 10min! It’s funny about your pinned comment. My first thought was golf ball dimples then micro dimples (but seeing your comment these woukd be useless!) and then finally uranium! I’ve actually wanted some for so long. I have searched how to buy uranium so many times I’m probably on a watchlist, apparently older aircraft counterweights used to be uranium.

You could make bank selling these for obscene prices to wealthy corporate types, these people love this kind of stuff. I’d ask at least $15K, give it some backstory about something or another that sounds profound, build a super exclusive and refined website for it, and bam! Big money! Excellent achievement, that’s some dope ass engineering shit right there.

I have nothing to do with spinning tops other than this random video which was recommended, but after visiting the record page and seeing the previous record holder, I have to say I was slightly more impressed with Iacopo Simonelli's run. The single twist start and the trueness of his top throughout, at least until 40mins of 51 was a touch more mesmerising to me. You're top seemed to start going through various wobble phases from 35mins on, maybe tip wear? None the less hats off for the determination and thanks for the interesting entertainment👍
@hiper_tops8 ай бұрын
I agree Iacopo’s tops are incredible! They have been an inspiration since the start. I aspire to achieve the seemingly perfect balance his tops have. Regarding the single spin, this really ought to be a separate category (and I think he would hold the record)
@iacoposimonelli71918 ай бұрын
Thank you, @antichicmusic. I don't think it's tip wear. Tungsten alloys have disomogeneous density so tops made with these materials are almost always less or more badly unbalanced, there can be also couple unbalance, not only static unbalance, so it takes some patience and knowledge to balance them perfectly.

Congratulations. It’s been so fun to watch your tops improve with each video. I don’t know how many hundreds of dollars this would cost to produce a small run, but I would back the hell out of that Kickstarter
@hiper_tops8 ай бұрын
Thank you :) To be transparent, if I were to make 10 or so Mk.22-like tops (something I am thinking about), they would be at least 600 USD each. Aside from the large material cost - especially the flywheel - it takes many hours of skilled labour on my part to get them to as high a standard as this. It's an economic puzzle! However I am very aware of the large demand and want to produce something so stay tuned😄

Good work! I dont know which physical phenomena is more fascinating, magnetism or rotating mass. There is a reason why both capture your attention at a very early age. Some accept they will never understand it, others are driven to madness trying. Mad on good sir. Might I suggest more extreme numbers, particularly at the low rpm end of the spectrum? Everything is more forgiving when performed at a more leisurely, although none less respectable pace. At some point toward the extremity, relative friction losses can be reduced to near nil.

"High Performance" Reminds me of the levels of precision with the rails of the Shinkansen (bullet train) in Japan. You'd be able to look out your window, at the next track over, line up the rail with the bottom of the window, and for a moment, it would just look like the rail was stationary, sitting just outside the window. It was that still to the eye.

I believe 1hour 30min may be around the soft limit for spinning tops of this type. I am hopeful that 1hour 10min will be broken by a design similar to Mk.22 :)

The harder the material at contact is, the less wearing it will have and the longer a polished surface will last and function... What if you were to use something like a tungsten carbide tip on a tungsten surface so it wouldn't be able to eat itself. Theoretically diamond would be perfect, but I find metals easier to work with in production. Well done breaking that record there!
@hiper_tops8 ай бұрын
Since the carbide is harder than the tungsten, it would drill into the base. In practice, a slightly harder base material is best. I think carbide on monocrystaline diamond would be ideal but it is very expensive and hard to find!!
