rudder core

[Stephen Dunn <steve100557@hotmail.com>]

Just started shaping the rudder core and I read somewhere that there is a 
problem with the leading edge tip hitting the fin when the rudder is 
deflected to the left. Is this a problem, and if so is it something I can 
address at this stage? The manual isn't very specific about the shape of the 
tip. Also, do the hinges need to be treated before being bonded to the 
rudder? Thanks,
                             Steve
