Ok - I built many boxes back in the day but none of them were great and I am trying to do a better job now.
I need to mount my 2 - 10" sub in a double baffle.
Yesterday I cut both pieces of the double baffle out and glued them together.
Now I want to cut the holes for the subs.
I do not have a router or a circle jig.
Is there a easy way to mark the circle out. I thought of using string but it seems hard to get to the right size. I wish I had a wooden ruler but I do not as I thought I could drill a hole on one end and another small hole 1/2 the dimension of the cutout.
So what is an easy DIY of marking a perfect circle for the cutout.
Also did I mess up by gluing the 2 - 3/4" MDF panels together before I cutout the holes?
