Reseña del editor El Maestro de Construcción es y ha sido el estándar de la industria para carpinteros y artesanos durante más de 30 años. Su uso se enseña en programas de aprendizaje y capacitación a nivel de secundaria, universidad, sindicato e industria en todo nuestro país y más allá. Toda una generación de framers y constructores de palos creció usándolo y asesorándonos sobre las nuevas capacidades que querían incorporar. Los materiales y técnicas de construcción han cambiado a lo largo de los años, pero la geometría y la necesidad de trabajar con rapidez y precisión con las dimensiones es tan importante y difícil como siempre.
