    How to cut holes for subs

    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?

    Thanks!

    Re: How to cut holes for subs

    Also, yeah gluing the baffles together makes it a good bit more difficult to cut especially with a jig saw. Even if the blade is long enough then there is a good chance that it will bend giving you an angled cut

    Re: How to cut holes for subs

    Should of cut them before you glued. Do you have a router? you can make your own jig or use a scroll saw.

    Re: How to cut holes for subs

    I have always glued them first then cut them but I use the correct blade for the material thickness and go slow, as for marking it out use a thin piece of drop and drill two holes the correct distance apart just like it were a ruler.

    Re: How to cut holes for subs

    Yea, that is not a good position to be in with both pieces glued together. Obviously since you have limited tools a jig saw is the only method and not really a great one for this situation. 1.5" of material to cut through is a pita though.
