[Konsta Mod] ShengShou 4x4 solution to internal lock-ups

Just to make it clear, I didn't even take my time doing it. I just shoved the pieces against a dremel to round them out and it has completely gotten rid of the lockups. I even was able to get a 27 today after doing the mod.

Out of curiousity, did you round up all the spots or just like in that first picture?
I was kinda surprised how fast you modded it.

WOW...that was ridiculously easy/fast and extremely effective. This definitely is the solution to the SS 4x4 lock-up problem. Thanks for posting up your pictures and idea!
Yes, I might have given wrong impression how long it takes to do this mod. I modded it very carefully as I didn't want to overmod anything after wrecking my megaminx, but the actual sanding/dremeling the parts shouldn't take that long if you have good tools and you know beforehand what to do. Altho I doubt I could do it as fast as Dan did, if he did all the spots I showed..
Especially the last pictures spot was hard for me to do, I found it to be pretty tricky spot to sand down without sanding something extra.

I only didnt mod the smaller section of the +centers. I rounded the outer contact point of both pieces as well as the inner point of the edges. I spent no time making sure it was accurate or pretty, so thats why it took me so little time. It seems that just rounding those corners does wonders for lockups, regardless of how much you actually round them off.
 
I sanded the hell out of all my SS4 V3 cubies and although it was a lot better, it still had the occasional outer layer lockup. I assumed that it was the small and big inner pieces that you have shown here, so I will try this mod and see how it turns out. Thanks

Those smaller sections of the +centers were the last thing I did to finish up this mod. But it might be just that I rounded less the inner point of the edges than you did.
But only after doing the last part I felt like the last tiny occasional internal lock-ups were truly gone.
It's good that people try to do mods a bit different ways so we get rid of unnecessary moddings :)
 
Its probably best to do both points of the contact, but I just was like... I'm not messing with these tiny pieces again :p I think though, if you round one of the pieces enough, that the other shouldn't ever catch on it because it is so rounded, which may be why I don't feel any lockups.

Hehe, I know how you feel. I was thinking of doing the smaller parts if the inner edge mod is not enough, but in the end just didn't want to take it apart again even tho I felt small occasional lock-ups.
Next day I had more energy to start modding again and did those annoying small parts on that last picture.
And yes, you're probably right about that rounding thing, I was just over-careful after destroying my favorite megaminx, so I rounded a bit on both parts instead of just rounding more on that edge part. Both ways might work equally well.
 
I took WAY too much plastic off of mine, now its all rough and bumpy, barely turns. Hopefully a bit of smoothing, breaking in, and Lubix will do the trick, but be careful, everyone.
 
Trying this tonight. With Harvard Spring coming up on Saturday, I really hope it works. I'd really like to cut a few seconds off my time by having very few lock ups

I'm sure you will like it. But be careful not to take too much like gokkar said, especially so close to competition where getting a new cube might be a problem :)

It seems I'm getting my SS 5x5 and 6x6 tomorrow, so a long modding day or few ahead of me 8)
