Good quality HAND SETTING KNOB 8mm BRASS Put a felt or paper washer between the knob and glass and rivet in place. Requires 3.25mm hole. Maximum glass thickness 3mm. There is no room for a washer The setting knob is designed to avoid Parallax errors on fine barometers. The setting hand needs to be as close as possible to the dial and this is normally done with a very thin hand, normally around 0.3mm thick. A paper or felt washer is put between the glass and the knob and a blind punch is used to spread the shaft to retain the hand without a washer. Some barometers are more of a decorative item than a barometer and the distance between the setting hand and the dial can be excessive. It seems to stem from the fact that whereas a clock should be accurate, it's quite acceptable for the barometer to be pointing at Dry while its raining! These decorative barometers can have thick hands and a washer to make the job of fitting the hand less likely to break the glass. Visit Our eBay Shop: The Clock Part Store
