So this cab also plays pinball games, and it needed pinball flipper buttons. The furring strips allowed for the button to be in place, but not the whole button nut. I clipped the nut to allow it to fit on the button shaft and the cab. I removed the button, spring, and switch. Then I super glued the threads of the nut, and placed it on the button shaft. Then I used gorilla glue between the nut and the furring strip near the contact points. This button is now super stable, but completely locked in place.
