Any unique ways to fix/mod/etc. the raised, rounded "nubs" on O-Matter arms after they get worn out, etc., & will not stay in their joints properly? As an example, Hijinx have holes that line them up through the bottom that you can actually "pin" them if you are gentle with a drill & tiny bit & small piece of metal, ... almost like that of a paperclip, but much more durable, ... straight piece of stainless ... believe me, it works ... I have done it for a lower side nub, & all the way up through for an upper, too. I had to fix my Artist Series'jinx all the way up through because the Seller did not disclose that the right arm would not stay in, & were only a display pair... sorry, but I wear my stuff. ... but now I have a pair I got - off eBay- some beautiful Unknown's - that the Seller did not disclose the right arm was Fd up somewhat ... just that these have a solid top & bottom. They are not horrible, they are wearable, but on occasion I find them popped out ... & it enrages me. Eh, ... ideas?
