1. A method of cutting and installing pieces of stock around a wall structure, the method comprising:

  • providing a system includinga saw device capable of pivoting about a pivot axis to cut pieces of stock at various selectable angles of a cutting plane of the saw device relative to a positioning path,a stop,a fence defining a fence plane that is vertical and parallel to the positioning path, wherein the cutting plane and the fence plane intersect one another to define a line when the saw device is oriented to make a square cut,a driver capable of moving the stop along the positioning path through a range of distances from the saw device, anda computer programmed to control positioning of the stop along the positioning path;

    cutting a first piece of stock with the saw device oriented left of a square cut, and a second piece of stock with the saw device oriented right of a square cut, wherein the first piece and the second piece of stock are cut for calibration of the system;

    measuring a first length of the cut first piece of stock and a second length of the cut second piece of stock;

    entering the first length and the second length into the computer;

    entering into the computer for a third piece of stock (a) a proximal corner angle of the wall structure where a proximal end of the third piece of stock will be fixed, (b) a desired length of the third piece of stock, and (c) a distal corner angle of the wall structure where a distal end of the third piece of stock will be fixed;

    allowing the computer to calculate an appropriate position for the stop and an appropriate orientation for the saw device to cut the third piece of stock, wherein the appropriate position for the stop includes a compensation for an offset of the pivot axis of the saw device from the line, and wherein the compensation is calculated by the computer based on the appropriate orientation for the saw device, the measured first length of the cut first piece of stock, and the measured second length of the cut second piece of stock;

    cutting and installing the third piece of stock;

    allowing the computer to determine an appropriate orientation for the saw device to cut a proximal end of a fourth piece of stock based on the distal corner angle entered for the third piece of stock;

    cutting the proximal end of the fourth piece of stock;

    entering into the computer for the fourth piece of stock (a) a desired length of the fourth piece of stock and (b) a distal corner angle of the wall structure where a distal end of the fourth piece of stock will be fixed;

    allowing the computer to calculate an appropriate position for the stop and an appropriate orientation for the saw device to cut a distal end of the fourth piece of stock;

    cutting the distal end of the fourth piece of stock; and

    installing the fourth piece of stock to form a miter joint with the third piece of stock.
