When the wood shrinks, the Teflon doesn't, which caused them to click. If we had Teflon pins inside Teflon bushings, even though the pins would not be effected, the wood would snhrink, and you get the clock. The only way to stop all the expansion is to make all the wood parts out of ABS, including the shanks. But I wonder if an ABS shanks would be flexible enough to withstand the force of a hammer hitting a string?
