[Rhodes22-list] cockpit bench seat reinforcement

[Lou Rosenberg]

RHODIES;
  Seeking advice on reinforcing the cockpit seats in my R22 ( 1981) . 
The boat is now secure on is trailer in its winter home in Bklyn 
thanks to Rick Centalaonza, a boat hauler ( Coastal)
  and some good boat yard folks in Pt Jeff and Bklyn.
  My stb side cracks when I walk or sit  on it, but is not broken. 
The glass work underneath is brittle and the wood stiffeners are 
missing .
  I have Casey's book on HULL & DECK repair and plan to stiffen and 
support the entire length of both benches by epoxing a dowel in the 
groove and then adding a triangular support made of pine ( since its 
not going to be seen much , teak is overkill, I believe).  The 
triangular support would need to be epoxied to the floor underneath 
the seats. I plan to space the  2 supports on each side  equally.

  Has anyone had weakening of their bench seating due to damage or 
weathering and age of the glass?
  I am wondering how the epoxied supports would react to the flexing 
of the boat later on as she is under strain.  Would it make sense to 
not epoxy the supports and just wedge them down with rubber mat under 
the wood?

  Any advice appreciated !
  thanks
