I built a video transmitter, and it works great! However, I'd like to attach a knob to the variable capacitor which tunes the frequency of the transmitter.
The capacitor looks like this:

I'm not sure how to attach a knob to a screw. I thought about soldering a shaft of metal to the screw and attaching a knob to that. I know solder isn't meant to be used as glue, but I'm happy with any solution as long as it works. The screw doesn't take much torque to turn (you can turn it with your fingernails) so I don't think the solder joint would snap off easily. Any better ideas?
