Cecil,

Its not how it looks, it's how it feels, that matters.

Conventional wisdom was to leave them springs loose.

Just get one tooth over slop on any split gear and be good.

Keep the gear train clean enough and lubed enough so that the small amount 
of spring tension is enough to keep the gears from lashing.

You spin the knob fast enough to get whip lash in the springs and you 
deserve to over shoot the signal. You are supposed to find it, roll off it, and 
then come back on to it slow. Do this faster in the hand than it takes to 
read the text here.

Over loading the springs just grinds brass off the gear teeth.
