Guhong comparison (Black Vs White) + Corner gapping fix

[Olji]

So, I read somewhere in this forum that the black guhong have plastic of lower quality compared to other colours, the price difference on Lightake made me a little curious, so I bought a black and a white to compare.
They arrived today (obviously) and here is my test of them:

Unlubed:

Both was rather crappy, but the black guhong was slightly faster in terms of speed, forgot to check corner cutting here :fp

Lubed with CRC Industrial Silicone(Image):

After lubing, work in and drying, I found the white to be slightly faster instead as well as being smoother than the black (the black was more clicky), corner cutting is about the same, not much difference there.

Both was assembled and lubed the same way, unmodded and having the same tension (as close I could get them at least),
the result may of course be a subject of consistency though, but I though I could put the review here still.


Over to the fix of the corner gapping

As most Guhong owners may have noticed, the Guhong can have a problem of the corner pieces having a gap, like this:

I decided to check what the problem was, and upon disassembly I found small molding imperfections:

(Can't get better quality out of my camera, its crap, but you can still see the imperfection a little)

To fix the gapping, disassemble the corner cubies into pieces, and check for and take away imperfections in this area on each piece:

upon assembly again, the piece should look like this if you did it right:

It is the same piece as before, after the "mod"

Is the cube after modding better or faster and has it a better corner cutting, I got is problem too?!

 

[Olji]

I havent done any mod to these except the corner gapping fix, and that is mainly for vision, we'll see if I get around to do the 48 point edge mod on these and assemble them back, right now they are 2 3x3 illusions >.<

 

[RubikZz]

Ok, and are the corners glued, or as an edge clicked together?

Edit: I now it, it is like an edge.

did u use 2 pegs for each corner piece? or just 1 peg each?

 

[Olji]

2 pegs, one on the front and one on the back, as its meant to be

I have major corner gaps on my Guhong, but when I disassembled my corners, there were no molding imperfections like the ones in your photo. What should I do?

 

[~Phoenix Death~]

I'll keep this in mind if I find the corner gap annoying. I don't right now.

 

[Olji]

the molding imperfections can be very small, check around that area with some ligth shining on it and see if it distrupts somewhere, maybe also see if there is something in the hole where the connector would be, pushing it up a little (may also be on the connector itself), some of my corners had almost invisible imperfections, checking with good lightning makes it easier to find them, it may also be on the edge of the hole, cant help you more than that

That is soo outdated... This does not exist anymore as the competition between the different makes grew bigger.

In the old days, there weren't a lot of rivals, nor were there much demand, in this business anyway. So most of the puzzles were made by the random no-name factories in China, which often uses impure plastic material and then dye them black to hide the impurity. But for white cubes, the presence of impurity is much apparent in the color, so there are less chances of the cube being made from recycled bottles.
But now that there are 10+ different makes competing with each other, they don't really have the guts to use low-quality material, as they would lose their sale if cubers find their product being much lower quality than their rivals. As compared to the old days, there wasn't much choices of speedcubes other than Rubik's, and when a cuber found a random cheap cube that actually turns well, it's usally produced by those no-name factories, and have to endure the low-quality material because Rubik's is a lot more expensive.

if you read the whole sentence, you would also have read about the price difference (3 dollars) between black plastic and any other color on lightake that made me a little curious.
The black and the white plastic do respond different to silicone sprays, so there is a small difference between them, it may be outdated, but the plastic is still different from eachother, just not as much as before

NOU, you fail.

Black - $12.79
White - $12.79

Black POM - $14.49
White POM - $14.49

Where's your difference? I don't see it.

I find it annoying because it makes a little clicky sound as you turn a face. My friend's guhong (we have both done the ultimate mod) doesn't have gaps and doesn't have this problem. We switched corners and sure enough, his cube started clicking. I just find that sound annoying.

How do I look for these? Would I just hold the hole up to the light? and if i find one, how would i get it out?
thanks!

yeah, use light and see if theres anything in there, and poke it out with anything thin (may also flush it out with water), I dont know if it can be imperfections in there, if there is, I guess you have to trim the connector down a little, but I only found the imperfections around the hole making it, since on some places, it made the connector unable to get down completely, and on other places it just made the gap by itself, since some places are touching when a corner is assembled, and if those places have some bumps it will probably be some gapping too

Lid got there before me, why didnt you take the DIY into consideration?

since u have 4 guhongs, are the 2 other 'old' guhongs different? the new ones have silver screws while the olds have black. is there any difference between the 2 in the core size or plastic?

 

[Olji]

only the first guhong I got had the black screw set and old core, although after I got my colored, I changed the screws, springs and core in hope of getting it as fast as the colored was (no success though, the turning just become less "creaky" (lol)), so if im comparing my old black with my new black, the new one is way faster and less controllable (its not modded though), the old one is modded with 48 point edge mod, is smooth, kinda slow and more controllable than a new guhong out of the box/newly assembled, will update with core size difference between old and new (havent though about that), but the plastic feels kind of softer on the old one, kinda gummy, may be because its broken in,

I always look up DIY's first, but mostly because I like to assemble the cubes, but I can agree, the difference between black DIY vs Assembled and same on any other color is weird, but I dont complain

u used the same lube for both cubes?

yep, CRC Industrial silicone
