Sonora Governor Parts/Adjustment
Posted: Tue May 01, 2018 2:53 pm
Hello,
I am completely new to these machines but I am a mechanical engineer and love tinkering. I recently received a Sonora Phonograph from my wife's family. Somewhere along the line, somebody made some repairs to the governor and it was a little out of whack. Luckily the weights are original, most of the screws are the same, but the spring steel strip that holds the weight had snapped at one of the screw holes and is barely hanging on by the fastener and one of the strips was replace all together. All the strips are a little bend out of shape compared to photos I have seen online (Attached) of the same setup. The Sonora plays but the it runs away on me as far as RPMs.
Can anyone explain to me how to adjust the governor along with the speed control friction pad? Any descriptions on how to adjust this setup would be really helpful, so far trial and error is all I can do.
Does anyone know where to find more of the type of spring steel used?
Thanks!
