This works really well actually.
Interesting. I'm not too keen on trying this out myself actually because I seem to be the only person who hasn't gotten squeaky gears.
Actually, most of my waist gears are starting to naturally lose friction...
I guess the dust just slowly starts getting rubbed away the more you play around with them.
I actually haven't used them much. My Pohatu and Umarak haven't been moved for months, and my Tahu I rarely use the actual waist gear to turn his body.
I guess it could just be the batch of pieces that I got.
lucky you !
I've never really had this problem/ it's never bothered me, but if it does, I will definitely keep this technique in mind.
