Dopey Tuning

[Kristinn Leifsson]

Howdy,

I´ve just dripped it in, until it the cavity won´t take any more.  When it 
starts to accumulate I stop.
Of course if the pins aren´t all that loose to begin with, I  don´t think 
pin tightener is necessarily the first step I´d take.

Others have more experience,

Kristinn
