hey guys i recently got my tremor yesterday, and i realized the centering was off ( to were it was rubbing the side) so i tinkered with the pivot screw and got off the side but still a little off. i also realized if i tighten the pivot screw tight enough to make it dead center the blade wont come out on its unless i flick my wrist. and solutions to make it more centered and have the blade come out on its own?
