I checked Google Books and found 'Carpentry Made Easy' by William Bell, based on a quick scan I think this is worthwhile book to study. As in real estate the three most important factors are location, location and location, Bells opening chapter in building math suggests to me that the three most important factors in carpentry are proportion, proportion and proportion. Bell addresses the pitch problem as a dicotomy between building specification and true inclination.


I suppose pitch has long been a source of confusion.
