Corner Cutting Help

[Deleted member 12389]

How did you all lube yours? I feel that maybe there needs to be some lube on the "internal" parts of the cubies that have the little "legs". I find that is what is causing the lock-ups.

Using Lubix's video, I lubed mine using diff oil (mixed - you can read it here)


My Guhong comes pre-assembled. I have another Guhong DIY (self assembly) I received last night. Will check if this comes with the 'problems' you face. Its black from lightake.

I cannot imagine your Guhong locking up/pop that bad...

Would maru lube work as well? I'm thinking of getting my own lube (I used my friend's before), and I want to try out some different ones. Also, fiftyniner, can you check how the pieces are molded together, if there are any gaps or anything?

My GuHong doesn't cut 45 degrees. To be honest, you don't really need 45 degree corner cutting unless your the world's laziest turner. My Stickerless GuHong cuts way over 45, but I still get the same times as with my regular GuHong.

You might just have to get used to the feel and break it in. You may wan to tighten it because mine's fast but I never have popping problems.

Hm, this is strange. My Stickerless GuHong cuts and turns way better than my black one too. But my Black one is POM and not lubix-lube, silicone spray lubed instead.

You could have just received a defective one. 1 out of 10,000 guhongs must have some type of defect. Also, your cube could have gotten damaged during shipping, if it was packaged poorly or there was an incident (something fell on it). Not Lightake's or factory's faults, just an accident, maybe.

1. The edge and corner pieces are pieced together manually. Yes there are gaps in the pieces, no matter how much pressure you apply to piece them together.
   
2. In your case, IMHO, any of the recommended lube (in the forum) should be good enough just to get your Guhong going. I have cube-lube clone, Japanese Speed Kit lube, Silicone spray, differential oil. My preference for Guhong - differential oil. Of course you may want to consider the much vaunted Lubix (which I don't have). IMHO - tight and smooth cube - low viscosity lube (as in spray or cube lube clone). Loose cube - high viscosity (as in diff oil)

FYI:

I assembled my new black Guhong last night. The corners were composed of 3 pieces held together by 2 small 3-legged pegs. The edges were composed of 2 parts. And yes, there were gaps despite the best pressure.

Lubing is simple - I dab two edges with difference oil. Did not even bother to lube the core (as in Lubix vid). Turn just as great. Loud and very rough. Some faces turn less than 45 deg. Interestingly, the turning degs increases (minutely) with the breaking in process.

I think, assuming that yours is not a defective Guhong, it would be the tension and the need to give the core time to become more flexible with time.

 

[radu242]

So I just loosened it all to the same tension, by doing it from the core and loosening all the sides the same amount from a set point in which they were all equal, and it hasn't changed much. It turns well if you are not cutting or anything, but once anything starts being slightly out-of-place or not aligned properly, everything just expands outwards from the core as I'm turning and locks.

 

[gundamslicer]

Did you loosen it enough? I would recommend abouut 8 half turns

 

[radu242]

gundamslicer: I did exactly that lol. I tightened everything to full tightness (or whatever) then I did 8 half turns.

 

[Nestor]

I just ordered 8 black GuHongs for myself and some friends...

Unlike my white DIY GuHong, which was already godly even before adjusting tensions / lubing it, these are no different than a common AV out of the box, they pretty much suck before modding and adjusting/lubing.

I've been reading stuff about white/colored GuHongs beings faster than black ones, is this true?

Some of my corners use to have some gaps, I read a thread (http://www.speedsolving.com/forum/showthread.php?28526-Guhong-comparison-(Black-Vs-White)-Corner-gapping-fix&highlight=GuHong) and I fixed it. Also, a good tension for GuHongs is about a penny (you tighten it and you pull and it should be about the width of a penny) I also recommend Diff Oil (50k WT, 30K if you can't find 50K)

How do you cut corners when having a tight tension?

So i like tighter cubes, but when i tighten it , my dayan zhanchi loses its ability to corner cut. With and without the torpedoes. I currently have no torpedoes, because it is more smooth. So how can i keep a tighter cube with the ability to corner cut atleast 45 degrees

 

[ThomasJE]

I would say lube it, and put the torpedos back in so it doesn't pop. If the torpedos make the cube rough, try sanding off the bumps on the corner base. Also, tighter tensions can sometimes make the cube more likely to pop, so just bear that in mind.

 

[VileShot]

I am going to lube it. I had lubix in it before, but i was an ***** and washed it off when experimenting with my cube. At the moment my cube never pops, my friends zhanchi who has torpedoes pops alot, because he likes the looseness. Still before and now, with tighter tensions i could not cut 45. it would just lock up. I might try the corner thing though. But anything else?

 

[ThomasJE]

Possibly breaking in and mods (48PEM, CPM etc)? And some people say the Zhanchi is better with the torpedos. But I suppose it's all down to personal preference.

 

[Ickathu]

I agree with Sahid, but if you would like it to be able to cut that much (which I do anyway, for OH and rough-turning noncubers who scramble for me sometimes), check out Cyoubx's tutorial on tensioning Dayan cubes.

(which is INSANELY long for some reason).

If you need extreme corner cutting I'd personally take a step back and look at your technique and question why it is necessary. You shouldn't really need more than a few degrees if you can turn relatively accurately.

 

[Ranzha]

Switch to a non-corner-cutting cube, improve your accuracy, and switch back.

This is terrible advice.

Do not intentionally switch to a worse cube lest you pick up bad habits.

No, not a worse cube. Same speed, without corner-cuts. Maybe a Maru. My Maru's quite fast, but it doesn't corner cut even ten degrees. After I switch back, it seems my cube's not as bad and I get good times.

By worse cube I mean something like a Rubik's brand--stupid, slow, and bad. Or, perhaps, maybe one can deal with locky cubes by just focusing.

 

[insane569]

Well what I do is practice a bit of 4x4 since it can't cut as much as a dayan. After acouple of solves I switch back and my accuracy is golden. Same for look ahead.
