[Boatanchors] Backlash in a National capacitor

[Ian Wilson]

Lee,

Very interesting, thank you. I disassembled the mechanism and discovered a
large
amount of crud on the worm. Cleaned this up. Reassembled and - beginner's
luck -
got it back together. However, I must have applied too much preload because
the
amount of torque required to operate was excessive. Upon second attempt -
goodbye
beginner's luck - all three of the tension springs decided to disconnect
themselves;
fortunately only on one end. I will see about reattaching them tomorrow.

Incidentally, the capacitor rotor shaft doesn't move as freely as I would
expect.
I imagine this worsens the backlash.
