This it what I would do. 
with a plunge router ....
Core Box Bits

V-Groove Router Bits

You can also use a Brass Guide with a template, If you Have A BIG one and your router can take on a big one...( 1 1/2" OD ) but if not the jig works well for this type of job, you can also put a counter sink slot in the jig so you can adjust it in or out, so you can use it for other jobs as well .
