I own a yamaha hip gig ,with floating toms and snare. i have started to notice that the wing screws that hold the arms where they sit are starting to give in and the drums swivel into weird positions at the slightest touch,no matter how tight the screws are . I Keep overtightening them until my hand hurts but nothing doing . I live in Ethiopia and can't get ANY SPARES AT ALL until i go home in summer,but my band here cant wait.This is horrible,mates.Is there anything at all I can do?HELP
