Hi Friends, One of my greatest tool is the pocket reference book by Thomas Glover ISBN 1-885071=00=0. The amount and diversity of knowledge is mind boggling. I got my copy as a gift but have purchased other copies for friends at the local lumber yard. As I remember it was under $10. It is small and the cover is black so it is easy to overlook. I use mine mainly to find out what different shapes of steel weights. Almost everyone could use one.
Enjoy, Chris
