I need to cut into the table where the dealers would stand. They will need to be able to reach across the table. The table is so huge, they (me) will need all the help they can get.

I marked a pencil line at the wall, and a rounded edge. Then cut with circular saw, and jig saw.

I used a 1/4″ roundover bit in the router and smoothed out the edges of the cutout on the walls.
