Gentlemen,
 As an occasional contributer to this list and a prospective builder in
the future, I will be attending the 2 1/2 day seminar on Lancair
Construction Techniques in Georgia  scheduled for mid Jan 99. I have
some glass/ wet lay up, and vacuum bagging experience.  I have also done
some carbon fibre/kevlar fibre, honeycomb and boron core construction on
race boats.  The question is "will I learn anything new at one of these
seminars"?
  
Are the techniques used in building an airplane vastly different?  
Also,  why are 'wet layup" techniques used instead of vacuum bagging?
It seems to me that the advantages of higher fibre to resin ratios and
lower overall weight combined with the more uniform finished part
dimensions would point to using the vac techniques.  My supposition is
that Lancair is concerned with the ability of builders to ensure correct
and complete wet-out prior to bagging to prevent "dry spots" in the
laminates.  Although more labor and skill intensive,  the ability to do
multiple layer layups may also be an advantage.  

Am I missing an obvious disadvantage?  Please let me know (I take
criticism very well).  I have never had the opportunity to actually see
the sequence of events for Lancair construction so I think this seminar
may turn on a few lights.  Comments and guidance are welcome.

  Thanks for the assist ...Jeffrey B. Chipetine.  N80121(spam for now)
