Replacement pully for 1935 Atwater Kent radio model 856

thingiverse

My other hobby is restoring old radios to their former glory. The Atwater Kent model 856 from 1935 boasts an innovative mechanism for tuning stations. I was fortunate enough to source replacement O-rings and gaskets at the time, but in my case, a crucial component - the pulley itself - was missing. Taking matters into my own hands, I decided to design and print a replacement. Who knows? Perhaps this will prove useful to someone else who encounters this same issue. As it turns out, the O-ring and gasket for this pulley are no longer widely available commercially. What's interesting is that these parts could potentially be recreated by studying the dimensions of either the original pulley or the printed one, and then 3D printing them using a flexible material like TPU.
