Bruce,

The radius is there to avoid stress cracks that form at sharp points.  

The radius doesn't need to be much: a 1/16" radius should be plenty.  
The aft end of the longeron has that notch in it just so it can fit  
around the bulkhead. Don't shorten your longeron, just extend your  
notch a little bit. Just enough to add a radius in the corner.

Mike

realized
after looking at your pictures I forgot to put the radius in the end of 
the
longeron when I trimmed out the piece.  Do you think that's much an 
issue?
Or should I shorten up the longeron just a bit to accommodate a radius?
Again, thanks for the help.
