Move the action parts to the start of escapement (jack tender
contacting the LO button) and then load grams weights onto the key
until, from a dead start these weights will overcome the escapement
friction. Remember that the escapement friction goes through its own
decreasing gradient as the jack moves out from under the knuckle.
Because of this, no "bumps" are allowed
