Question regarding mounting hardware. Has anyone found a better material for the mounting points to get better sound than with the standard rubber? I have seen a number of odd "hacks" of the mounting, from using play field post rubber, to metal washers, to plastic. Didn't really play with hearing how they sounded, just replaced.

Back to William's chimes. I am refurb'ing an OXO. Have had problems with previous William's chime boxes sounding bad. So tried something new. Put the chime bar grommets that normally fit tightly inside the holes of the bars, on the posts first. Then put the bar on top of the grommet. Cut the plastic post sleeve in half to shorten it, then put the small metal retainer bar and long pin on top of the cut sleeve. This isolates the chime bar from the retainer bar, and lets the chime bar kind of float on the grommet. Sound was much better on all three lengths of chime. Still not a Gottlieb, or anywhere near the 3 and 4 inch bells in my 1960's Mayfair, but better than normal for Williams.

Try leaving off the silicone washer between the chime and retaining bars. Use the tube around the post to create a gap between the two bars. Yes they click together when the chime bar is struck, but only for a split second. This helped the sound of mine on OXO.
