Pre Cut MDF circles?

[agarabaghi 10+ year member]

Does anyone sell pre cut MDF circles.

Im going to build a box, and I would like to mount my sub slightly flush or recessed. The easiest way I tough would be to cut a circle to the size of my subs outer diameter...

Outer diameter: 10.5inches

And then build a ring that is maybe 2 - 3 inches thick and cut out to the mounting diameter of the sub...

Inner diameter of the circle: 9.25"

Outer diameter of circle: 12.25"

Then i could glue / screw the circles to front baffle...

Suggestions?

Afraid of the router? It's OK, after a few box builds it'll just become another tool, and not an "oh god it makes a horrible noise and the bit is hot it's going to eat me."

WTF are you building an enclosure or just trying to mount a sub to the rear deck or something where is this sub going that you need to cut a ring for it?

Yea, and it seemed like the easier way would be to cut a 10.5 inch circle in the box, and then attach a ring to back, glue / screwed with the mounting diameter of the sub.

Most ppl just make the enclosure and cut a circle out of another sheet and stack that on top then ur def flush and its pretty easy even with a jig saw //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Really though if ur just using a jig you should sand the circle out to make it look nice.

We have a router, but ive never used it lol. Is there an attachment for dewalt routers to cut circles? I got the circle attachement for my dremel and will be trying that, but i hear it takes a while to cut through mdf =P

Outside diameter on the first baffle, cutout diameter on the second baffle. Or same baffle, you get it.

they make attachments for routers to do perfect circles. You'll have to find one.
