How we do it:
We use Dowels aligned along the center line of the part. We drill
two alignment holes along the vertical centerline of the part, one
on the top and one on the bottom of the line. Next we extend those
drilled holes into a sacrificial board clamped to the router
table.
Insert dowels into the work piece and down into the sacrificial
board. Clamp the work piece down and machine the first side. Flip
the part over and use the dowels to align it. Clamp back down and
machine the second side.
