I have a band saw mill to setup this spring so I can saw some lumber to fix my barns. Having never run a mill before and only having an ok understanding of different species of wood and lumber I have been doing some reading.
Understanding Wood a Craftsman's Guide to Wood Technology
by R Bruce Hoadley
This is my latest book to expand my understanding of wood it is really well written with an amazing depth of information not only about the wood structure and specie but also about how to look at the structure of the wood when you saw it and work with it to get the best quality out of each log. I am very impressed with this book but I will have to go back several times and re read it because there is alot of information in it.
