Trying to put a straight edge on several long, thick boards and hoping
there is a good way of using a router and a jig that someone could
recommend.

I use a 2x2x1/8x96 extruded aluminum angle from the Home Depot and a
couple of 3" C-Clamps along with a 3/4 straight bit in a fixed base
router.

Works for me.

YMMV

You could also make a jig by using a piece of 1/4 ply about 3 wide,
centered and glued onto a piece of 1/2 ply about 12 wide.

First pass will trim 12 wide piece dead nuts.

After that, place cut edge on desired cut line..
