Bored and poking around I dug into the Wiki Home page and found WikiBooks, well you've got to look and there it was a Wikibook on woodturning.
Not 100% sure wgere it's being written from, but the British (AWGB and RPT) are listed under Woodturning Organisations. The main author appears to be someone called Derek Andrews but nothing appears to be added since 2010, so if you feel you'd like to participate and add an article, I'm sure it would be appreciated.
