Fix a vintage radio tuner string

There's already some very nice tutorials on vintage radios, but I had a specific problem:  

• the radio turns on
• the radio makes noise, and gets louder with the volume knob
• but turning the tuning knob does not move the needle or change the station

Fortunately this can be solved: we have to re-string the tuning knob.

Step 1 Disassembly 1: remove knobs

We need to get the radio open.

On these old radios, the last thing to go on was the knobs.

Therefore, the first step for us is to remove the knobs.

These knobs pull straight off; they aren't glued or screwed on.

Pictured: the offending tuner knob.  The inner knob is the AM/FM selector.  The translucent ring is the tuner.  You can see how it's toothed on the inside.

cool quite through. I like how you did more of an explanation & overview than a instructable on that specific model.
