I've added a stem calculator in the form of an Excel spreadsheet to the More info/Sundries page - self-explanatory notes to be found there. Please persist if it seems baffling at first, rather than asking me! Just remember the starting position is a standard 73/17 degree stem, horizontal. Everything is relative to that.
