I bought a shorter router bit. It'll a down cutting spiral hing bit. Often used to make the recesses for door hinges. I need to build some doors soon so this purchase was a no brainer, despite the rather expensive $42. It's not shown in the photo, but it came with another bearing that's about an 1/8" over size. Ill route the WG recess with the over sized bearing first, then the flush 1:1 bearing. The reason for this is down currying spirals have difficulty clearing the cuttings from the end of the bit. They are great for minimizing tear out, which is why I went this method in the burl. But they're a bit of a fight to push through the wood. So I'll cut using the big bearing and then the flush bearing should just be a breeze taking off a small amount. This should give a cleaner cut. I already had this one, but it's also down spiral 1/2" and I'll use it for the woofer cutout. Here's a test cut. Not fully recessed. And I gotta say, it looks bad in the photos, but great in real life. A slight gap all around makes me think twice about remaking the template. I'm not sure its worth it, but I hate to regret it. I gotta decide it I want it super tight, or a little room. Like I said, the photo looks at it in the worse possible angle.
