Thanks everyone! More pics to come as the week continues. The entire audio build should be completed sometime next month.
Yeah the router/string worked very well. When it came time to make the circle we needed a compass but didn't have one that large. the only thing we could think of was using string, a nail, and a pencil. Then when it was time to cut we decided to try the string again. it took a little bit to get the string the correct length but in the end it worked awesome! The real trick was getting the string to NOT wrap around the nail as the circle was cut. Once that problem was solved it was as easy as 1, 2, 3.
