No logo on 3BLD?

[SpedCube]

or do what i do, and use the tornado v3 until the logo comes off from use lol

So I'm wondering: will this be accepted as a valid BLD cube? I'd like to know before US Nationals if I could somehow.

my center cap has the same issue, but i've used the cube in several rounds of 3bld and it's always been accepted. it should be legal. i personally can't distinguish it by feel.

Another followup on this. I did get some blank center caps for my Tornado, and here's what they look like:

Looks great, right? But if I put it in the right light, it becomes possible to see a pattern deep in the plastic that sort of matches the logo (probably to make it take the logo better?):

Still hard to see here, but it's a little easier to see in real life. The actual pattern looks just like the normal logo on a tornado, but just the outline of it (a stylized fat X) in the white plastic.

And if not, we're back to my previous question: what's the best BLD-legal 3x3x3 on the market today?

I know Max Siauw uses the tornado for bld so it should be legal. Either way you probably should ask a delegate before competing.

Blank Center Cap for GAN12/13 UV

This is a blank UV coated center cap for the GAN12/13. If you do blind solving or just enjoy your own logo, this should do the trick.

This also exist for tornado v3 and gan 11 Uv.

The photo I included above was exactly one of these center caps for the tornado v3 which I purchased from thecubicle. As I said, my concern is that there is a slightly visible (in the right light) sign of a logo on these "blank" center caps.

I have a similar situation on my MoYu RS3M Super Ball-Core - I erased the logo to make it invisible but in the light you can kind of tell it was there once. Delegates have let me use it for blind in the past with no hesitation. There could be delegates out there who wouldn't be okay with it but I doubt that's common.

Since it seems like the idea behind disallowing logos is to prevent the delegates from having to work too hard to determine whether a logo can be felt, one would hope that if it requires very careful examination to spot something, it would be considered an acceptable cube. Otherwise the whole purpose of the regulation is destroyed - the delegate will need to very carefully examine all cubes under really strong light in order to be fair to those who might get unlucky and have a cube like this "spotted" and rejected. If that's necessary, all of a sudden it is just as easy to require the delegate to feel the cube to see if the logo can be felt - better to switch to a regulation based on feel rather than appearance, since visual inspection is just as hard as inspection by feel.

That's nice, but I am curious - how good is it? If you hold it in the right bright light, will you still see nothing? The reason I wonder is that these center pieces I got have never had the logo on them - they were sent before they were printed. So it seems like the plastic pieces themselves are made with a sort of "logo" in them. So it would seem to me that a process like this would still leave that in the plastic. Is that not the case?

As for the claim in the video that it is completely clean when done, I wonder if that's true for GAN but not for Tornadoes.

Edit: I ordered the polish; I will try it and report back here how it does on the Tornado.

I used MOTHERS brand, $5 at Walm Art...
I have not tried it on my XMD Tomato v3 Flagship (I dont do BLD) but it is still just a logo printed onto the surface of the plastic...

However I did use it on a GAN iCarry and it worked well, no sign of logo under 5000k+ 5500 lumens LED light at my desk and not outside in bright sunlight either ...

and as I mentioned I used it to polish all six sides of a couple "frosted" cubes and it does work well... tho doing all six faces entirely was a bit of a pain lol

My understanding is that the micro-particles in the polish literally allow one to remove layera of micro-particles of plastic from the piece(s) of a cube (and plastic is not as hard to polish as aluminum ha)...
also, yes, as he said in the video, it does come out shiny

 

[Mike Hughey]

Well, I bought exactly that Mothers brand, and tried it on my Tornado V3 Pioneer.

As advertised, it took the printed logo off perfectly.

But unfortunately the logo pattern in the plastic is still there just the same as it was on the blank I bought from thecubicle.

The logo pattern is completely invisible even under a very bright fluorescent light. No matter how I turn it, I can't see it.

But under a very bright daylight LED bulb, it is quite visible when turned at the proper angle. The X-man logo, but only in outline.

I tried reapplying the polish several additional times, just to see if it would help after a little more work, but no luck. If anything, it becomes more pronounced, since the overall polish of the piece is better so the shininess of the logo outline is more obvious. Although again it can't be seen under fluorescent light.

So I still wonder if this is considered a legal cube. Considering the circumstances, I think a ruling should be officially made by the WCA as to whether it is accepted, since otherwise rules will be applied differently at different competitions by different delegates. Since it seems quite clear that the logo cannot be felt, it seems to me the right ruling would be that the cube should be allowed as long as the printed logo is fully removed. But it would be nice to have an official ruling.

The only thing i know about logos is that you can peel them off, or just scrape sugar on it.

I just tried removing the logo. The problem is that even after removing it, there is still a hint of the logo imbedded in the plastic, which no amount of peeling or scraping can remove.

I tried it a few days ago, but i dont see anything on the center (X-Man Tornado V3)

 

[Mike Hughey]

I can only see it under a bright LED daylight bulb, when held at the proper angle. Otherwise it looks like your picture. But it's very definitely still there.

Honestly like I said, I oolished the GAN kogo off of 2 iCarry's tul I couldn't see any left on the cap... and even 2 frosted cubes entirely which took a fair bit of time and elbow grease but it worked fine...

My best guess is that somehow the manufacturers use some kind of Laser Etching process to lut the logo on there... 乁⁠(⁠ ⁠•⁠_⁠•⁠ ⁠)⁠ㄏ

Sorry it didn't work out perfect for you, I can understand your overall frustration...
and I agree that the nub of this conundrum is that the WCA needs to upgrade regulations concerning such things, especially since one can only see the embedded logo faintly under bright lighting, which is not applicable to BLD solving
[edit: I sure didn't mean to lead you astray @Mike Hughey ]

 

[Mike Hughey]

I'm not concerned about anyone misleading me, but right now I'm wondering if I need to go buy a GAN after already having bought 2 Tornados just so I can have a quality cube for 3BLD.
