Heh...
I decided to save my money and just cut the holes with a coping saw. I brought the stuff over to my Dad's for thanksgiving. He likes working with his hads and I figured it would be a good way to spend some time together.
The work was frustrating and time consuming, but we both had a good time talking and joking and catching up. I'm glad we did it.
But after we were done he said to me, "That would have been a lot easier if we has used a router."
Me: "I know. I really wanted to use a router for this job, but there just wasn't any easy way to get my hands on one."
Dad: "Really? I have a router. We should have used it."
Me: "WHAT!!! Why didn't you say so?!"
Dad: "Because you said you wanted to use the coping saw. If you were looking for a router you should have called me."
All these years, and I still haven't learned. Oh well, the time we spent together was fun, even if my speakers do look like crap.
