Hello all, Mostly work on antique wall, mantel, and Grandfather clocks. Friend brought me a round Pam light up clock with outside glass missing. Ordered the bubble glass through timesavers. With hands set as low to dial as possible and barely missing each other. Tip of Second hand still rubs the inside of domed outer glass, and makes that wet finger going around the edge of a glass sound Question is: Was there some sort of spacer used between advertising flat glass, and outer domed glass that would have held it out slightly farther?
