Indeed, all lever contacts with the exception of the jack tail with 
the letoff button, contact on the line of centres at half blow. The 
jack tail approximates a rolling action across the face of the 
lett-off button. Therefore, there is no need for any slip coating to 
be placed on the jack tail with our action.

Typically with a down-weight of 50 grams the up-weight will be 35 grams.

Best,
Ron O.
