I spent about an hour over at BF and couldn't find the original post. The seach engine doesn't seem to go back past the change in forum software. The more I think about it the more I think that 10" might be on the conservative side of Sal's recommendation, one of the problem's of relying on an ageing memory <img src="smile.gif" width=15 height=15 align=middle>. It may have been more like 12" or 14" but we'll have to hope Sal sees this thread and helps me out. Anybody else remember seeing the thread in question?
Don't worry that the world might end tomorrow, in Australia it's tomorrow already.
