Fallingwater,

Thanks for your comments.  I always find that my thinking is about three 
years behind yours!

I have to disagree with this.  Why do you need horizontal stiffness, other 
than to provide for the "bow" effect of the horizontal tube and the back pad?  
The joint need not be welded and rigid, but could be flexible (helping to make 
it more comfortable to walk with), yet provide sufficient horizontal rigidity 
to make the "bow".  I'm trying to make a pack that can carry only 30 lbs or so 
max, not the 75 or more that Kelty's were made to carry.   

I too have tried to lighter my old Kelty and quickly gave up as there is just 
too much there, and, well, I love it too much to take it apart!

I love tinkering and this is just what I need.  Thanks for the tip on bending 
the tubes.

Best regards,

Greg
