This has probably been covered...however I did not see a 'search' within a particuliar circle, and am not too familiar with this site.
I'm trying to find the best way to cut holes for the drivers?

What have you guys found to be easy and efficient (clean)?

If you have a router the best bet is the Jasper Jig.

Great recommendation.  The Jasper circle jig works great.

BTW, Jasper works with only a plunge router.

You can drill a hole a little bigger than the size of the router bit at the edge of the radius of the circle and still use the Jasper if you don't have a plunge router.
