This jig is for squaring off the edges.  I just need to get close to 90 degrees.

 

A few passes on the underside (pith).

 

But strips straight and squared.......

 

....and ready for initial, or rough planing.

 

I sanded these three nodes on the belt sander instead of the displacement done to the others.  These three will be cut away later when I get to trimming the rod sections to final length after glue up.   No point wasting time on displacement when not required.
