Hi Howard,

Is this the same radio chassis that you list in your "New Member" post? If so, we need to combine to make one thread. In addition, this is likely not a 39-7 as the 39-7 is a 5 tube radio with a rather plain tuning cap.

The gear is likely not turned by the vernier shaft; it is turned by the coarse shaft and the vernier shaft turns the course shaft. Can the coarse shaft be turned?

Like Rich states, soak the part in lacquer thinner. Liquid Wrench, Sili-Kroil and PB Blaster are also good. Heat may also be needed ad all clips may need to be remove and the device completely disassembled. Do so in an old pot as the ball bearings will roll right into a parallel dimension that will open up for the part but not for you. If you have to hammer, don't hammer on the vernier shaft, hammer on the coarse shaft using sockets as arbors.

Hope this helps.
