Gonna have to call bs on you there chief. Depending on the head of the screw the center may be recessed deeper on some than others but the drive is the same. Now a Frearson head screw looks similar to a phillips head screw, but the drive is much more narrow and actually requires a special driver to use. A phillips driver won't fit a Frearson screw. I don't have the hardware in front of me, but they may be combination heads. In which on line of the cross is extended to the edge of the screw. This allows you to use either a phillips or flathead screwdriver to make adjustments. There are wood screws that use a flat head with an X in the middle that extends to the edge of the screw completely. These are intended to be used with a flathead screwdriver and have no recess to them. A phillips head screwdriver will not fit these screws either. However the screws used for cubes are machine screws, not wood screws.

Is there a list of Guimond OLL algs that DO NOT affect the V? I'm thinking of switching to VOP.

Have bad v7, so ss7x7 or 8x8??

ss7x7

[theZcuber]

in both of those cases it would be a +2

Incorrect. 2 tiles off is a +2, but 3 is a DNF

I left my Dayan Zhanchi inside my bag and I think some stuff has gotten into it. It has made the cube turn very slowly and sluggish. I've tried to lube it and tension it, but that barely made a difference. How can I fix this problem?

Wash all the pieces in the sink, or dishwasher, but not the core! You might have to take the pieces themselves apart in order to dry it properly

I just put together my first dayan zhanchi. If it's not super tight, it feels, and is about to fall apart. It's very clunky and rough. Does anybody know why, or how to fix it? Should I order a new one?

[samchoochiu]

did u try evening the tensions and tightening it?

[Maru Ohashi]

Yup. If I made it any tighter it wouldn't turn at all. It feels like the pieces are going to fall out.

Need help with the case in my avatar pic.

Best known solution to date for immediate solve is M U M U M U2 M' U M' U M' U2. This alg is also the setup from a solved cube. Looking for a shorter or more finger friendly (RU) alg. Most alg's I've tried for "H shaped" OLL require further U perm's and such.

Avatar is depiction of case. Hoping to post more of why I'm looking for this and how I solve the cube. I am in the process of reviewing all related threads and wiki's to see if my method is already known. Top layer, bottom layer, middle layer last. I've only recently started with learning alg's since my method only uses 4 to solve, with an intuitive first layer and also R layer edges. But I'm plateau'd at sub 50. I am able to now tweak my method to include F2L and I have a deadbrain trigger to get LL to one of 3 different OLL cases. This allows for only needing to recall 3 OLL and probably all PLL's. But mostly I've only run into G, U, Y & T. I run into this mostly solved state with only two flipped solved middle edges quite often and would love a faster way through it or some advice on how to avoid it. (other than quitting)

example solve using old method: After intuitive first layer is done, leave one white middle piece out to use as a keyhole, turn white face towards the left. execute alg repetition(U' R2 U R U' R U){outside twist} to solve bottom corners. NOTE: After each outside twist, R will have to be positioned to the correct orientation. 0 corners orientated = x2 ; 1 corner orientated = BR (making sure the color for that bottom is facing right); 2 corners orientated = the two solved are positioned towards you or FR U & D ; 4 corners orientated but not solved = U' R' U F R2 F' U' R U{inside extended twist} ; 4 corners orientated but with two solved = the two solved are positioned away from you or BR U & D and then execute U' R' U F R F' U' R U{inside twist} You may need to execute the outside twist (or even another inside twist but only twice maximum) a couple more times to come to a four corner solve state in the R face. Once there you will see that all corners are solved and three edges on the L face are solved. The next step is to intuitively place R edges (and the last L edge) into their places keeping the keyhole in the U face to allow movement. There are some tricks to land multiple edges into place at the same time, especially for the last two. Once L and R face are complete only 4 edges are left in the M slice, which can be orientated using M U2 M' U2 {top twist} If you notice an edge fall into place, you should place the solved edge to the bottom and away from you or BDM and then execute your one or possible two remaining top twists. At last we come the the third twist which started this all. Chances are your cube will be solved at the end of your 1st, 2nd or 3rd top twist however at times you will encounter flipsolves which can only happen in pairs and they take (as far as I know) 12 moves to solve and the U face will resemble a H-shaped OLL. I've seen solves where top twisting will get you 2 pairs of flipsolved edges with an extremely long 24 moves to solves.

So if you've gotten this far and can understand some of what I'm talking about, I would love to forget this method and go with something new to me, however, I thought I would ask if there is a decent alg-utility or if anyone else knows how to get this "third twist" shorter.

My faster single on this TopBottomMiddle method is 47.07 with little or no traditional finger triggers. I'm hoping against hope that Kirsjava will come through with a better LL method.

Might be a feature, not a bug, I like my ZhanChi tighter than looser. Tighten all sides as much as possible so all sides are equal, and then work backwards by doing quarter or eighth turns with the screwdriver. Also make sure it's lubricated, that makes a difference with ZhanChi's
