Method for automatically fastening deck boards to stringers

A method for automatically fastening a plurality of deck boards to a plurality of stringers, comprising the steps of:

• a. providing a counterweighted pivotably mounted fastener gun above each stringer;
• b. providing a positioning means on each said fastener gun to automatically raise and lower the position of said fastener gun as the height of the deck board varies, each said counterweight serving to counterweight the combined weight of each fastener gun and each positioning means;
• c. providing an automatic firing means for said fastener guns;
• d. providing said firing means with a plurality of automatic switch means, responsive to the forward motion of the deck boards, for automatically firing said fastener guns as said deck boards pass in contact with said automatic switch means;
• e. positioning the plurality of stringers and deck boards beneath the counterweighted fastener guns;
• and
• f. firing the fastener guns by means of the automatic switch means being activated by the forward motion of the deck boards.
