I've heard hat NASC are now onto this kind of thing and are bringing out WG20:14 or as its more commonly known, Wood Guidance 20:14; it's apparently a 200 page document ranging from matchsticks to bamboo.
It has all the necessary WOODWIND calculations although you do need to REED it cover to cover or face being prosecuted under section 33 of The Health and Safety at Work Etc Act 1974.
I for one applaud this new money making guidance and will be heavily investing in some new gear and a rickshaw.
