Taking a detour from my
#cylinderplayer project to look at a friend's Columbia
#Grafonoloa #recordplayer. The symptoms are that if you turn the crank, you get a little resistance, then a little "klunk" sound, and then it freewheels. Sounds like a spring issue. Either detatched from the shaft or broken.
I should have taken a picture of the whole player, but here's the extracted mechanism, which I brought home to look at. And an add that shows more or less the model I'm working on,
Seems to be a deluxe triple-spring one, which gives you extra-long runs on a single wind, but means there's more places to check for a break.
That ad shows a girl listening to a Grafonola on a camping trip, like a steampunk iPod. I guess you could, but these things are a bit heavier than an mp3 player!
