ABSTRACT:
An adaptable system for precise cutting ends of 2.times.4 type lumber to form chords and webs for wooden roof trusses basically includes (a) a protractor unit formed of a plate member and a guide member, (b) horizontal table means including an upper surface supporting the protractor unit and upon which the lumber is supported in use of the system and (c) a radial arm saw. Stucture details of the protractor unit are disclosed. The system is relatively much less expensive than prior known precision roof truss member cutting devices and its method of use is quickly learned by sawyers.
