Tried to do a search but not seeing one on this topic. I've got several cymbal stands that have loose collars. By this I mean the collar that the tubes or rods slide into. Two of these are on Gibraltar JZ series stands and one is on a Ludwig flat base stand. I know these aren't the highest quality stands on the market but I like them for their light weight and when functioning properly they do just what I need them to. I've tried to make sure those tightening collars are pressed down as solid as they can be into the stand but the still turn. Anybody else experience this problem and more importantly any help with a fix for it?
